Protein: D-rhamnosyltransferase WbpZ (EC 2.4.1.-) (GDP-D-Man:GlcNAc-diphosphate-lipid alpha-1,3-D-mannosyltransferase) (EC 2.4.1.348) (GDP-D-Man:GlcNAc/GalNAc-diphosphate-lipid alpha-1,3-D-mannosyltransferase) (GDP-D-rhamnose:GlcNAc/GalNAc-diphosphate-lipid alpha-1,3-D-rhamnosyltransferase) (Q9HTC0)
Organism: Pseudomonas aeruginosa (strain ATCC 15692 / DSM 22644 / CIP 104116 / JCM 14847 / LMG 12228 / 1C / PRS 101 / PAO1)
Function: Non-processive alpha-1,3-D-rhamnosyltransferase. Catalyzes the transfer of one D-rhamnose (D-Rha) residue from donor substrate GDP-D-Rha in alpha-1-3 linkage to both GlcNAc- and GalNAc-diphosphate-lipid acceptor substrates. Is also able to transfer D-mannose (D-Man) to these acceptors at a lower level. Nucleotide sugars GDP-D-Rha, GDP-Fuc, UDP-Gal, UDP-GalNAc, UDP-GlcNAc and CMP-sialic acid cannot act as donor substrates. Only compounds with a diphosphate as the aglycone group can act as acceptor substrates. No activity is detected with compounds containing a diphosphate mimic. Fluorescent undecyl-anthracenyl group-containing compounds, such as GlcNAc-PO(3)-PO(3)-AnthrU and GalNAc-PO(3)-PO(3)-AnthrU, are also good acceptor substrates. Involved in the biosynthesis of the common polysaccharide antigen (CPA), also called A band, which is one of the two major cell surface O-antigens of the P.aeruginosa lipopolysaccharide. Involved in susceptibility to antibiotic colistin.
