poly-beta-1,6 N-acetyl-D-glucosamine synthase. Members of this protein family are biofilm-forming enzymes that polymerize N-acetyl-D-glucosamine residues in beta(1,6) linkage. One named members is IcaA (intercellular adhesin protein A), an enzyme that acts (with aid of subunit IcaD) in Polysaccharide Intercellular Adhesin (PIA) biosynthesis in Staphylococcus epidermis). The homologous member in E. coli is designated PgaC. Members are often encoded next to a polysaccharide deacetylase and involved in biofilm formation. Note that chitin, although also made from N-acetylglucosamine, is formed with beta-1,4 linkages.

poly-beta-1,6 N-acetyl-D-glucosamine synthase.

Glycosyltransferase, catalytic subunit of cellulose synthase and poly-beta-1,6-N-acetylglucosamine synthase [Cell motility].

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.
