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         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}.
