MODIFIED alpha -1,2-FUCOSYLTRANSFERASE GENE AND PROCESS FOR PRODUCING alpha -1,2-FUCOSYLTRANSFERASE AND FUCOSE-CONTAINING SUGAR CHAIN

摘要

A gene having been modified in the base sequence of alpha -1,2-fucosyltransferase gene originating in Helicobacter pylori; a process for producing alpha -1,2-fucosyltransferase by using this gene; and a process for producing a fucose-containing sugar by using a microorganism with the expression of the above enzyme. Thus, a fucose-containing sugar can be economically produced in a large amount by bringing a receptor sugar into contact with a microorganism capable of producing GTP from a GTP precursor and a microorganism capable of producing GDP-fucose from a sugar and GTP in an aqueous medium.
