CC -!- CATALYTIC ACTIVITY:
CC Reaction=[(1->4)-beta-D-glucosyl](n) + UDP-alpha-D-glucose = [(1->4)-
CC beta-D-glucosyl](n+1) + H(+) + UDP; Xref=Rhea:RHEA:19929, Rhea:RHEA-
CC COMP:10033, Rhea:RHEA-COMP:10034, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:18246, ChEBI:CHEBI:58223, ChEBI:CHEBI:58885; EC=2.4.1.12;
CC -!- PATHWAY: Glycan metabolism; bacterial cellulose biosynthesis.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000305}; Multi-pass
CC membrane protein {ECO:0000305}.
CC -!- DOMAIN: There are two conserved domains in the globular part of the
CC catalytic subunit: the N-terminal domain (domain A) contains the
CC conserved DXD motif and is possibly involved in catalysis and substrate
CC binding. The C-terminal domain (domain B) contains the QXXRW motif and
CC is present only in processive glycosyl transferases. It could be
CC involved in the processivity function of the enzyme, possibly required
CC for holding the growing glycan chain in the active site.
CC -!- SIMILARITY: In the N-terminal section; belongs to the
CC glycosyltransferase 2 family. {ECO:0000305}.
CC -!- SIMILARITY: In the C-terminal section; belongs to the AcsB/BcsB family.
CC {ECO:0000305}.
