The one-pot multienzyme (OPME) synthesis of human blood group H antigens and a human milk oligosaccharide (HMOS) with highly active Thermosynechococcus elongates α1-2-fucosyltransferase.

ABSTRACT

A novel α1-2-fucosyltransferase from Thermosynechococcus elongatus BP-1 (Te2FT) with high fucosyltransferase activity and low donor hydrolysis activity was discovered and characterized. It was used in an efficient one-pot multienzyme (OPME) fucosylation system for the high-yield synthesis of human blood group H antigens containing ß1-3-linked galactosides and an important human milk oligosaccharide (HMOS) lacto-N-fucopentaose I (LNFP I) on preparative and gram scales. LNFP I was shown to be selectively consumed by Bifidobacterium longum subsp. infantis but not Bifidobacterium animalis subsp. lactis and is a potential prebiotic.
