cellulose synthase catalytic subunit; Provisional

cellulose synthase catalytic subunit (UDP-forming). Cellulose synthase catalyzes the beta-1,4 polymerization of glucose residues in the formation of cellulose. In bacteria, the substrate is UDP-glucose. The synthase consists of two subunits (or domains in the frequent cases where it is encoded as a single polypeptide), the catalytic domain modelled here and the regulatory domain (pfam03170). The regulatory domain binds the allosteric activator cyclic di-GMP. The protein is membrane-associated and probably assembles into multimers such that the individual cellulose strands can self-assemble into multi-strand fibrils.

CESA_CelA_like are involved in the elongation of the glucan chain of cellulose. Family of proteins related to Agrobacterium tumefaciens CelA and Gluconacetobacter xylinus BscA. These proteins are involved in the elongation of the glucan chain of cellulose, an aggregate of unbranched polymers of beta-1,4-linked glucose residues. They are putative catalytic subunit of cellulose synthase, which is a glycosyltransferase using UDP-glucose as the substrate. The catalytic subunit is an integral membrane protein with 6 transmembrane segments and it is postulated that the protein is anchored in the membrane at the N-terminal end.

Cellulose synthase catalytic subunit A2 (CESA2) is a catalytic subunit or a catalytic subunit substitute of the cellulose synthase complex. Cellulose synthase (CESA) catalyzes the polymerization reaction of cellulose using UDP-glucose as the substrate. Cellulose is an aggregate of unbranched polymers of beta-1,4-linked glucose residues, which is an abundant polysaccharide produced by plants and in varying degrees by several other organisms including algae, bacteria, fungi, and even some animals. Genomes from higher plants harbor multiple CESA genes. There are ten in Arabidopsis. At least three different CESA proteins are required to form a functional complex. In Arabidopsis, CESA1, 3 and 6 and CESA4, 7 and 8, are required for cellulose biosynthesis during primary and secondary cell wall formation. CESA2 is very closely related to CESA6 and is viewed as a prime substitute for CESA6. They functionally compensate each other. The cesa2 and cesa6 double mutant plants were significantly smaller, while the single mutant plants were almost normal.
