Abstract
Helicobacter pylori α1-3/4-fucosyltransferase (Hp3/4FT) was expressed in Escherichia coli at a level of 30 mg L-1 culture and used as a diverse catalyst in a one-pot multienzyme (OPME) system for high-yield production of l-fucose-containing carbohydrates including Lewis antigens such as Lewis a, b, and x, O-sulfated Lewis x, and sialyl Lewis x and human milk fucosides such as 3-fucosyllactose (3-FL), lacto-N-fucopentaose (LNFP) III, and lacto-N-difuco-hexaose (LNDFH) II and III. Noticeably, while difucosylation of tetrasaccharides was readily achieved using an excess amount of donor, the synthesis of LNFP III was achieved by Hp3/4FT-catalyzed selective fucosylation of the N-acetyllactosamine (LacNAc) component in lacto-N-neotetraose (LNnT).
