4-alpha-L-fucosyltransferase glycosyl transferase group 56
This family contains the bacterial enzyme 4-alpha-L-fucosyltransferase (Fuc4NAc transferase) (EC 2.4.1.-) (approximately 360 residues long). This catalyzes the synthesis of Fuc4NAc-ManNAcA-GlcNAc-PP-Und (lipid III) as part of the biosynthetic pathway of enterobacterial common antigen (ECA), a polysaccharide comprised of the trisaccharide repeat unit Fuc4NAc-ManNAcA-GlcNAc.
