CC -!- FUNCTION: Catalyzes the transfer of the GlcNAc-1-phosphate moiety from
CC UDP-GlcNAc onto the carrier lipid undecaprenyl phosphate (C55-P),
CC yielding GlcNAc-pyrophosphoryl-undecaprenyl (GlcNAc-PP-C55), the lipid
CC intermediate involved in the synthesis of various bacterial cell
CC envelope components. The enzyme is highly active when tested with C35-
CC P, instead of its natural C55-P lipid substrate, suggesting that at
CC least a 35-carbon chain is required for the lipid to be a substrate of
CC WecA. {ECO:0000269|PubMed:18723618}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=di-trans,octa-cis-undecaprenyl phosphate + UDP-N-acetyl-alpha-
CC D-glucosamine = N-acetyl-alpha-D-glucosaminyl-di-trans,octa-cis-
CC undecaprenyl diphosphate + UMP; Xref=Rhea:RHEA:28090,

CC ChEBI:CHEBI:62959; EC=2.7.8.33;
CC Evidence={ECO:0000269|PubMed:19442646};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000269|PubMed:18723618};
CC -!- COFACTOR:
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000269|PubMed:18723618};
CC -!- ACTIVITY REGULATION: Partially inhibited by magnesium at concentration
CC higher than 10 mM and totally inhibited at concentration higher than
CC 250 mM. Also inhibited by tunicamycin, NaCl and KCl.
CC {ECO:0000269|PubMed:18723618}.
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=0.12 mM for C55-P (at pH 8 and at 65 degrees Celsius)
CC {ECO:0000269|PubMed:18723618};
CC KM=0.62 mM for UDP-GlcNAc (at pH 8 and at 65 degrees Celsius)
CC {ECO:0000269|PubMed:18723618};
CC pH dependence:
CC Optimum pH is 8. {ECO:0000269|PubMed:18723618};
CC Temperature dependence:
CC Optimum temperature is 65 degrees Celsius. At 30 degrees Celsius
CC activity is only 7% of the optimal value and at 80 degrees Celsius,
CC the enzyme is totally inactive. {ECO:0000269|PubMed:18723618};
CC -!- PATHWAY: Cell wall biogenesis; cell wall polysaccharide biosynthesis.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC protein {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the glycosyltransferase 4 family. WecA
CC subfamily. {ECO:0000305}.
