CBP_BcsG is a component of bacterial cellulose synthase complex that plays a role in biofilm formation in bacteria [1]. It is a Zn(2+)-dependent phosphoethanolamine transferase that catalyses transfer of phosphoethanolamine residues from membrane phosphatidylethanolamine to the glucosyl residues in the nascent cellulose chain [2-5].
