Secondary metabolites: fundamental and niche-specific roles in fungal development andcell-cell interactions

An exhaustive characterization of the set of non-ribosomal peptide synthetase (NPS) genes of the corn
pathogen, Cochliobolus heterostrophus, and the small molecule peptides produced by the enzymes they
encode, has been undertaken to ascertain what peptide secondary metabolite products are doing for thefungal cell. Non-ribosomal peptide synthetases (NRPSs) are multimodular enzymes that make small
non-ribosomal peptides (NRPs) through a mechanism, independent of organelles best known for protein
synthesis, the ribosomes. To date, the NRPS method of peptide biosynthesis has been described forfilamentous ascomycete fungi (and to a limited extent, for basidiomycete fungi) and for bacteria, only. The
diversity of possible NRP products is potentially limitless as NRPs can be composed of D- and L-aminoacids, protein and non-protein amino acids, hydroxy acids, ornithine, b-amino acids, and other unusual
constituents. Furthermore, NRPs can be linear, cyclic, or branched cyclic, and may be modified byglycosylation, N-methylation or acylation. In addition to structural diversity, NRPs have an astonishingly
broad spectrum of biological activities, many of which have been useful in medicine, agriculture, industry,and biological research. However, despite the fact that activities of the peptide products with respect tointeractions with other organisms are well-documented, and certainly remarkable, to suggest that this is theirprimary function is likely incorrect. For example, only one of the 12 C. heterostrophus NPS genes is requiredfor virulence on the host, maize. In fact, the physiological significance of these small peptides to the
producing fungi is largely unknown. We document that NRPS enzymes are purveyors of small molecules forboth basal metabolism and for specialized environmental niches. Certain NPSs are required for sexual
reproduction, asexual reproduction, virulence, as nutrient ‘gatherers’ (such as iron-gathering siderophores),for responses to oxidative, nitrosative, nutrient, pH stress etc, for growth, and for hydrophobicity. Our
results indicate that 8 of the 12 C. heterostrophus NPS genes are not conserved, while four are conserved inother ascomycetes, and we have examined functional conservation of conserved genes in the wheat pathogen,Fusarium graminearum, and the Arabidopsis pathogen, Alternaria brassicicola. Comprehension of
secondary metabolite function, from the perspective of the fungal cell itself, impacts our understanding ofevolution of fungal pathogenicity mechanisms by addressing how pathogens become pathogens.

Fungal Nitrate and Nitrite Transporters: Insights into Structure and Function
Shiela E Unkles and James R Kinghorn,
University of St Andrews, United Kingdom
Nitrate is a major source of nitrogen for microbes and plants and it is a nutrient that most frequently
limits their growth. In the natural environment, nitrate is the most ephemeral of inorganic nutrients,
concentrations varying by as much as five orders of magnitude. Nitrate is readily leached from soils,
contributing to eutrophication of natural water systems and simultaneously lowering nitrogen availability toland organisms. In addition, nitrate based fertilisers, widely used at around 1011 kg per annum to improve
crop yield, have the inherent disadvantage of cost, globally costing roughly US$50 billion. There are also
health concerns as nitrogen oxides derived from nitrate may be generated in the human gut.
Nitrate is converted to nitrite by the enzyme nitrate reductase and then to ammonium by nitrite
reductase activity. Ammonium is used for the production of organic nitrogen molecules including aminoacids. Whilst there is considerable information regarding nitrate and nitrite reductases, there is significantly
less on the transport of nitrate and nitrite into cells. This first step in the assimilation of nitrate to ammonium,
involves the influx of nitrate into cells, an active process that may require up to 25 kJ mol-1, depending upon
external nitrate concentration. Two nitrate transporter proteins are present in Aspergillus nidulans, NrtA
(formerly CrnA) and NrtB, and both are high-affinity systems. The A. nidulans nrtA gene was the firsteukaryotic gene encoding high-affinity nitrate transporter to be isolated and has acted as a paradigm for suchhigh-affinity systems, leading to the cloning and identity of orthologous genes from a number of species,
including A. oryzae (which has a single nitrate transporter). A secondary structure model was proposed forthe 57 kDa (507 amino acids) NrtA protein in which 12 hydrophobic transmembrane domains (Tm) inalpha-helical conformation, pass through the membrane connected by hydrophilic loops. The NrtA
homologues belong to a distinct cluster (nitrate-nitrite porter family, TC 2.A.1.8) of the largest secondarytransporter family known, the major facilitator superfamily (MFS: TC 2.A.1) that comprises a vast range offunctionally diverse transporters, each containing motifs characteristic of the superfamily (Fig. 1, positions
marked by MFS). Recently, the three dimensional structures of three bacterial MFS members have been
determined, the oxalate (OxlT: TC 2.A.1.11.1), glycerol-3-phosphate (GlpT: TC 2.A.1.4.3) transporters andlactose permease (LacY: TC 2.A.1.5.1). Although the primary sequence similarity between these and NrtA is
low, comparative modelling to these structures has allowed us to develop a three dimensional representationof NrtA (Fig. 1).
Fig. 1. Three dimensional representation of
NrtA as viewed from the side within theplane of the membrane.

13Several Tms of NrtA are predicted by helical wheel analysis to form amphipathic α-helices
suggesting that the hydrophilic faces of such Tms could form the lining of an aqueous pore through which
nitrate is channelled. Among the amino acids of these helices, are a number of residues that are highly
conserved in all nitrate transporters, with at least 95% conservation in 52 proteins from archaebacteria,
eubacteria, fungi, algae and plants. Some of these amino acids are found within a motif present in all nitratetransporters,
F/Y/K-x3-I/L/Q/R/K-x-G/A-x-V/A/S/K-x-G/A/S/N-L/I/V/F/Q-x1,2-G-x-G-N/I/M-x-G-G/V/T/A which is
not observed in any other classes of MFS proteins. This residue stretch has been referred to as the nitratesignature of which there are two copies within NrtA, located in Tm 5 and Tm 11. The first copy contains ahighly conserved (48/52) polar asparagine residue, N168, while in the second motif, N459 is conserved ineukaryotes. Also prominent are two charged polar arginine residues, R87 and R368, which are completely
conserved in both prokaryotes and eukaryotes, within helices Tm 2 and Tm 8, respectively. Towards gaining
an understanding of the importance of residues and their role in the structure and function of this importantanion transporter, we have altered these amino acids and characterised the resulting mutant strains using theshort-lived tracer 13NO3-. Possible roles of such residues in the function of NrtA will be discussed as well as
progress towards crystallographic structure determination.
The anion nitrite can also be used as a source of nitrogen by many bacteria, algae, fungi and plants.
Certain nitrate uptake systems such as A. nidulans NrtA and NrtB have been shown to transport nitrite aswell as nitrate. In addition, there are transporters that appear to transport nitrite, but not nitrate. These include
Escherichia coli NirC, Chlamydomonas reinhardtii NaR1 and A. nidulans NitA (and A. oryzae NitA and
NitB). Such proteins as belong to a family, quite separate from the MFS, namely the formate/nitritetransporter family (FNT: TC 2.A.44), and many are thought to transport nitrite and/or the structurally related
formate. In contrast to the nitrate transporter group, members of the FNT family probably possess 6 Tms andare therefore much smaller (at the primary protein sequence level) than NNP proteins, the A. nidulans NitA
protein possessing 310 residues. A secondary structure model of the A. nidulans 33.6 kDa NitA protein isgiven in Fig. 2. Multiple sequence alignments of 186 proteins have indicated several residues and motifs thatare conserved within this family and therefore are likely to be involved in the function of these proteins.
These are clear targets for analysis by mutagenesis followed by biochemical characterisation and this will be
discussed. Unlike the MFS family, there are no crystal structures as yet for the FNT family and our progress
towards this goal will be reported.

The nsdC gene encoding a novel positive regulator of sexual development of Aspergillus
nidulans is regulated by complicated transcriptional and post-transcriptional control.
Hye-Ryoun Kim and Dong-Min Han (Division of Life Science, Wonkwang University, Korea )The nsdC gene which is predicted to encode a putative transcription factor carrying a novel type of zinc finger DNA
binding domain consisting of two C2H2 and a C2HC motifs acts as a positive regulator of sexual development in A.
nidulans. Two distinct transcripts, 3.2 and 2.8 kb, are synthesized and the smaller one differentially accumulates invarious stages of growth and development as well as under the varying nutritional conditions. 5’ RACE and Northernblot analysis revealed that there were at least two alternative transcription initiation sites which might be responsible fortwo kinds of transcript in different size. Two alternative transcription termination sites were also found through 3’
RACE and Northern blot analysis of nsdC deletion mutant. The gene carries two relatively long introns in its 5’UTR,
one of which is spliced alternatively. The results suggest that the expression of nsdC is controlled by complicatedtranscriptional and post transcriptional regulations.

Molecular analysis of the rapamycin-sensitive and cycloheximide-resistant ActA1 gene in
Aspergillus nidulans
Sun-Hee Noh and Suhn-Kee Chae (Dept. Biochemistry and Biomed RRC, Paichai Univ. Daejeon, 302-735 Korea)
The TOR (Target Of Rapamycin) pathway has been implicated in regulation of cellular responses to nutrients.
During the course of screening of rapamycing-sensitive and -resistant mutants in A. nidulans, we observed that
rapamycin sensitivities of FGSC stock strains were correlated to the presence of the ActA1 mutation in the strains. In
order to isolate the cognate gene responsible to rapamycin-sensitivity, we took an approach of complementation of an
ActA1 mutant with a genomic DNA library. Transformant was selected based on their wild-type sensitivity to
rapamycin. The yeast GCN20-like gene was identified from the complementing region in the transformant. Sequencing
analysis of its gDNA and cDNA predicted that the 2,596 bp-long ORF encoded a putative ATP-binding cassette protein
and was interrupted by 8 introns. This ActA1 complementing DNA region was mapped to chromosome III near ActA
indicating that the complementing clone was not a suppressor of ActA1. The ActA1 mutant allele was amplified andsequenced. The mutant allele ActA1 contained point mutations at 393rd and 394th amino acid residues. ΔActA displayed
resistance to cycloheximide, but failed to show rapamycin sensitivity. Although ǼGCN20 of S. cerevisiae is sensitive
to 5'-MT, over-expression of ActA did not complement its 5'-MT sensitivity. [Supported by KRF]

Cluster analysis of microarray gene expression data during growth of Aspergillus oryzae incellulose substrate medium
Avid SHIAU, Praveen Rao JUVVADI, Jun-ichi MARUYAMA, Manabu ARIOKA, Katsuhiko KITAMOTO (Dept. of
Biotechnology, Univ. of Tokyo)
The filamentous fungus, Aspergillus oryzae, has been widely recognized as a safe organism and its importance for the
food industry, such as for the production of useful enzymes has been well established. The recent release of its complete
genome sequence has attracted fungal biologists and prompts investigations into its potential to be utilized for wider
biotechnological applications. We have designed custom array (Affymetrix Inc.) consisting of 12,050 genes from A.
oryzae. To understand the cellular machinery of biomass degradative processes/potential in A. oryzae, we studied the
genome wide expression data during its growth on cellulose as a substrate. A 24 h pre-grown culture of A. oryzae
RIB40 strain in Czapek’s Dox (CD) medium was shifted to CD medium supplemented with 2% Avicel and cultured fora further period of 8 h.

The labeled cRNA prepared from the total RNA was hybridized onto the A. oryzae microarray.

The genome wide expression data obtained was processed and compared to similar data originating from RIB40 grownon CD-Glucose medium. Of the 12,050 genes examined, a positive expression profile consisting of 3,454 upregulated
genes was produced. At the same time, data was retrieved using the comprehensive glucoside hydrolase database at
CAZY and 52 predicted cellulolytic genes (cellobiohydrolases, endoglucanases and beta-glucosidases) were identified
in A. oryzae. Fifteen of these hydrolases were found to be at least 2x upregulated in the positive expression profile.
Within this subset, the promoter of each gene will be analyzed for the cis-element binding sequences that are commonly
found in promoter regions of fungal hydrolytic enzymes.
