CC   -!- FUNCTION: Catalyzes the synthesis of Und-PP-GlcNAc-ManNAcA (Lipid II),
CC       the second lipid-linked intermediate involved in enterobacterial common
CC       antigen (ECA) synthesis. {ECO:0000255|HAMAP-Rule:MF_01001}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=N-acetyl-alpha-D-glucosaminyl-di-trans,octa-cis-undecaprenyl
CC         diphosphate + UDP-N-acetyl-alpha-D-mannosaminouronate = beta-D-
CC         ManNAcA-(1->4)-alpha-D-GlcNAc-di-trans,octa-cis-undecaprenyl
CC         diphosphate + H(+) + UDP; Xref=Rhea:RHEA:28366, ChEBI:CHEBI:15378,
CC         ChEBI:CHEBI:58223, ChEBI:CHEBI:61495, ChEBI:CHEBI:62959,
CC         ChEBI:CHEBI:70731; EC=2.4.1.180; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_01001};
CC   -!- PATHWAY: Bacterial outer membrane biogenesis; enterobacterial common
CC       antigen biosynthesis. {ECO:0000255|HAMAP-Rule:MF_01001}.
CC   -!- SIMILARITY: Belongs to the glycosyltransferase 26 family.
CC       {ECO:0000255|HAMAP-Rule:MF_01001}.
