EpsO protein participates in the methanolan synthesis. The Methylobacillus sp EpsO protein is predicted to participate in the methanolan synthesis. Methanolan is an exopolysaccharide (EPS), composed of glucose, mannose and galactose. A 21 genes cluster was predicted to participate in the methanolan synthesis. Gene disruption analysis revealed that EpsO is one of the glycosyltransferase enzymes involved in the synthesis of repeating sugar units onto the lipid carrier.

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.
