Protein attributes

Sequence length	729 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	Catalytic subunit of cellulose synthase. It polymerizes uridine 5'-diphosphate glucose to cellulose, which is produced as an extracellular component for mechanical and chemical protection By similarity.
Catalytic activity	UDP-glucose + (1,4-beta-D-glucosyl)(n) = UDP + (1,4-beta-D-glucosyl)(n+1).
Cofactor	Magnesium By similarity.
Enzyme regulation	Activated by bis-(3'-5') cyclic diguanylic acid (c-di-GMP) By similarity.
Pathway	Glycan metabolism; bacterial cellulose biosynthesis.
Subcellular location	Cell inner membrane; Multi-pass membrane protein Potential.
Domain	There are two conserved domains in the globular part of the protein: the N-terminal domain (domain A) contains the conserved DXD motif and is possibly involved in catalysis and substrate binding. The C-terminal domain (domain B) contains the QXXRW motif and is present only in processive glycosyl transferases. It could be involved in the processivity function of the enzyme, possibly required for holding the growing glycan chain in the active site.
Sequence similarities	Belongs to the glycosyltransferase 2 family.
