CC   -!- FUNCTION: Catalyzes the conversion of GlcNAc-PP-undecaprenol into
CC       ManNAc-GlcNAc-PP-undecaprenol, the first committed lipid intermediate
CC       in the de novo synthesis of teichoic acid. {ECO:0000255|HAMAP-
CC       Rule:MF_02070}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=UDP-N-acetyl-alpha-D-mannosamine + N-acetyl-alpha-D-
CC         glucosaminyl-di-trans,octa-cis-undecaprenyl diphosphate = N-acetyl-
CC         beta-D-mannosaminyl-(1->4)-N-acetyl-alpha-D-glucosaminyl di-
CC         trans,octa-cis-undecaprenyl diphosphate + UDP + H(+);

CC         EC=2.4.1.187; Evidence={ECO:0000255|HAMAP-Rule:MF_02070};
CC   -!- PATHWAY: Cell wall biogenesis; poly(ribitol phosphate) teichoic acid
CC       biosynthesis. {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the glycosyltransferase 26 family. TagA/TarA
CC       subfamily. {ECO:0000255|HAMAP-Rule:MF_02070}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=BAA95012.1; Type=Erroneous initiation; Note=Truncated N-terminus.; Evidence={ECO:0000305};
