glucans biosynthesis glucosyltransferase MdoH.

Glucan_BSP_MdoH catalyzes the elongation of beta-1,2 polyglucose chains of glucan. Periplasmic Glucan Biosynthesis protein MdoH is a glucosyltransferase that catalyzes the elongation of beta-1,2 polyglucose chains of glucan, requiring a beta-glucoside as a primer and UDP-glucose as a substrate. Glucans are composed of 5 to 10 units of glucose forming a highly branched structure, where beta-1,2-linked glucose constitutes a linear backbone to which branches are attached by beta-1,6 linkages. In Escherichia coli, glucans are located in the periplasmic space, functioning as regulator of osmolarity. It is synthesized at a maximum when cells are grown in a medium with low osmolarity. It has been shown to span the cytoplasmic membrane.

CESA_like is the cellulose synthase superfamily. The cellulose synthase (CESA) superfamily includes a wide variety of glycosyltransferase family 2 enzymes that share the common characteristic of catalyzing the elongation of polysaccharide chains. The members include cellulose synthase catalytic subunit, chitin synthase, glucan biosynthesis protein and other families of CESA-like proteins. Cellulose synthase catalyzes the polymerization reaction of cellulose, an aggregate of unbranched polymers of beta-1,4-linked glucose residues in plants, most algae, some bacteria and fungi, and even some animals. In bacteria, algae and lower eukaryotes, there is a second unrelated type of cellulose synthase (Type II), which produces acylated cellulose, a derivative of cellulose. Chitin synthase catalyzes the incorporation of GlcNAc from substrate UDP-GlcNAc into chitin, which is a linear homopolymer of beta-(1,4)-linked GlcNAc residues and Glucan Biosynthesis protein catalyzes the elongation of beta-1,2 polyglucose chains of Glucan.

Glycosyl transferase family 2. Diverse family, transferring sugar from UDP-glucose, UDP-N-acetyl- galactosamine, GDP-mannose or CDP-abequose, to a range of substrates including cellulose, dolichol phosphate and teichoic acids.
