UDP-N-acetyl-D-mannosaminuronic acid transferase, WecB/TagA/CpsF family [Cell wall/membrane/envelope biogenesis].

glycosyltransferases MtfB, WbpX, and similar proteins. This family is most closely related to the GT4 family of glycosyltransferases. MtfB (mannosyltransferase B) in E. coli has been shown to direct the growth of the O9-specific polysaccharide chain. It transfers two mannoses into the position 3 of the previously synthesized polysaccharide.

The glycosyltransferase WecG/TagA superfamily contains Escherichia coli WecG, Bacillus subtilis TagA and related proteins. E. coli WecG is believed to be a UDP-N-acetyl-D-mannosaminuronic acid transferase, and is involved in enterobacterial common antigen (eca) synthesis. B. subtilis TagA plays a key role in the Wall Teichoic Acid (WTA) biosynthetic pathway, catalyzing the transfer of N-acetylmannosamine to the C4 hydroxyl of a membrane-anchored N-acetylglucosaminyl diphospholipid to make ManNAc-beta-(1,4)-GlcNAc-pp-undecaprenyl. This is the first committed step in this pathway. Also included in this group is Xanthomonas campestris pv. campestris GumM, a glycosyltransferase participating in the biosynthesis of the exopolysaccharide xanthan.

Glycosyl transferase WecB/TagA/CpsF family.

phosphatidyl-myo-inositol mannosyltransferase. This family is most closely related to the GT4 family of glycosyltransferases and named after PimA in Propionibacterium freudenreichii, which is involved in the biosynthesis of phosphatidyl-myo-inositol mannosides (PIM) which are early precursors in the biosynthesis of lipomannans (LM) and lipoarabinomannans (LAM), and catalyzes the addition of a mannosyl residue from GDP-D-mannose (GDP-Man) to the position 2 of the carrier lipid phosphatidyl-myo-inositol (PI) to generate a phosphatidyl-myo-inositol bearing an alpha-1,2-linked mannose residue (PIM1). Glycosyltransferases catalyze the transfer of sugar moieties from activated donor molecules to specific acceptor molecules, forming glycosidic bonds. The acceptor molecule can be a lipid, a protein, a heterocyclic compound, or another carbohydrate residue. This group of glycosyltransferases is most closely related to the previously defined glycosyltransferase family 1 (GT1). The members of this family may transfer UDP, ADP, GDP, or CMP linked sugars. The diverse enzymatic activities among members of this family reflect a wide range of biological functions. The protein structure available for this family has the GTB topology, one of the two protein topologies observed for nucleotide-sugar-dependent glycosyltransferases. GTB proteins have distinct N- and C- terminal domains each containing a typical Rossmann fold. The two domains have high structural homology despite minimal sequence homology. The large cleft that separates the two domains includes the catalytic center and permits a high degree of flexibility. The members of this family are found mainly in certain bacteria and archaea.
