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 at the onset of the stationary phase, when the cells exhibit multicellular behavior (rdar morphotype). Coexpression of cellulose and thin aggregative fimbriae leads to a hydrophobic network with tightly packed cells embedded in a highly inert matrix 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.
