Abstract
Lewis x (Lex) and sialyl Lewis x (SLex)-containing glycans play important roles in numerous physiological and pathological processes. The key enzyme for the final step formation of these Lewis antigens is α1-3-fucosyltransferase. Here we report molecular cloning and functional expression of a novel Helicobacter hepaticus α1-3- fucosyltransferase (HhFT1) which shows activity towards both non-sialylated and sialylated Type II oligosaccharide acceptor substrates. It is a promising catalyst for enzymatic and chemoenzymatic synthesis of Lex, sialyl Lex and their derivatives. Unlike all other α1-3/4- fucosyltransferases characterized so far which belong to Carbohydrate Active Enzyme (CAZy, http://www.cazy.org/) glycosyltransferase family GT10, the HhFT1 shares protein sequence homology with α1-2-fucosyltransferases and belongs to CAZy glycosyltransferase family GT11. The HhFT1 is thus the first α1-3-fucosyltransferase identified in the GT11 family.
