title: Heating induced temperature difference measurements from the modular buoy 2020M26: 04 s after the heating cycle

description: Temperature and heating-induced temperature differences were measured along a chain of thermistors. 2020M26 (a.k.a. Bruncin IMB042) is an autonomous modular instrument that was installed on drifting sea ice in the Arctic Ocean during the 4th leg of MOSAiC in June 2020. The thermistor chain was 5 m long and included 256 sensors. The resulting time series describes the evolution of temperature and temperature differences after three heating cycles of 4, 20 and 24 s as a function of place, depth and time between 26 June 2020 and 19 August 2020 in sample intervals of 1 hour for temperature and 6 hours for temperature differences. In addition, this modular buoy consisted of sensors measuring position (GPS) and barometric pressure at hourly intervals. The buoy was installed on a ridge, called Jaridge that was studied during leg 4, in the MOSAiC Central Observatory. This instrument was deployed as part of the project Ridges - Safe HAVens for ice-associated Flora and Fauna in a Seasonally ice-covered Arctic OCean (HAVOC), funded by the Research Council of Norway (project number 280292).
description: The data set has been processed and contains quality flags for different kinds for erroneous data. Flag values are the sum of individual error codes. The value of 0 refers to no error. Quality flag, position: The geographic position is flagged +1 if the drift velocity, as derived from the GPS longitude and latitude, exceeds a threshold of 10 deg latitude or 50 deg longitude per time step; +2 if the position exceeds extreme values, such as longitude &gt; 360 deg; +4 if the position is exactly 0.0.

title: Specific RubisCO activities of yet uncultured Proteobacteria depending on flanking genes

description: Here we used the first solely activity-based approach for identifying RubisCO active fosmid clones from a metagenomic library. Hydrothermal vent fluids derived from the interface zone between hot fluids emanating from Drachenschlund and ambient cold seawater at 8°18'S/13°30'W served as initial sample for library construction. Among 1056 screened fosmid clones 12 exhibited RubisCO activity. The metagenomic fragments of all twelve clones resembled genes from Hydrogenovibrio crunogenus. One of these clones was further analyzed. It contained a 35.2 kb metagenomic insert carrying the RubisCO gene cluster and flanking DNA regions. Knockouts of 12 genes and 2 intergenic regions on this metagenomic fragment demonstrated that the RubisCO activity was significantly impaired and was attributed to deletions in genes encoding putative transcriptional regulators and those believed to be vital for RubisCO activation. Our new technique revealed a novel link between a poorly-characterized gene and RubisCO activity.

All fosmid clones were constructed with pCC1FOS vector and Epi300 as a host. The activity measurements were performed at 25°C in buffer A [100 mM Tris HCl (pH 7.8), 10 mM MgCl2, 1 mM EDTA, 25 mM NaHCO3, and 1 mM DTT] with 0.2 mg unpurified, total protein, and 5 mM ribulose 1.5 bisphosphate (Rubp), whereby Rubp addition is the initiation step. Quantification of RuPB and 3-PGA was done using High Pressure Liquid Chromatography (HPLC) (LaChrom Elite® system, Hitachi) with a Lichrospher® 100 RP 18e column (VWR International GmbH, Darmstadt, Germany), detection at 200 nm, acetonitrile as an eluent, and a flow of 0.6 ml per minute.

title: Influence of flanking genes on Gammaproteobacterial form I and II RubisCO functioning

description: Since the majority of all microorganisms are currently not culturable, we used a metagenomic approach to identify genes and enzymes associated with RubisCO expression. The investigated metagenomic DNA fragment originates from the deep-sea hydrothermal vent field Nibelungen at 8°18'S along the Mid-Atlantic Ridge. It is 13,023 bp and resembles genes from Thiomicrospira crunogena. The fragment encodes nine open reading frames (ORFs) which include two types of RubisCO, form I (CbbL/S) and form II (CbbM), two LysR transcriptional regulators (LysR1 and LysR2), two von Willebrand factor type A (CbbO-m and CbbO-1), and two AAA+ ATPases (CbbQ-m and CbbQ-1), expected to function as RubisCO activating enzymes. To date, only one study has ever investigated regulatory mechanisms in metagenome-derived RubisCO gene clusters (Böhnke and Perner 2015). Here, total RubisCO activity was significantly influenced when cbbL and cbbM neighboring genes were knocked out (Böhnke and Perner 2015), but it remained unclear which of the two RubisCOs was primarily affected by these mutations. Our study suggests that CbbQ-m and CbbO-m activate CbbL and that LysR1 and LysR2 proteins promote CbbQ-m/CbbO-m expression. CbbO-1 seems to activate CbbM and CbbM itself appears to contribute to intensifying LysR's binding ability and thus its own transcriptional regulation. CbbM furthermore appears to impair cbbL expression.
