| 2.4.1.65 | D336A |
fucosyltransferase III mutant enzyme shows reduced activity with a variety of acceptors, 40fold reduction in activity for Fucalpha(1,2)Galbeta(1,3)GlcNAc. 4fold reduction affinity for GDP-fucose. The single amino acid site Asp336 of FucT III and Ala349 of FucT V constitutes the only difference in the sequence of FucT III and V over the final 210 COOH-terminal amino acid residues, impacts the acceptor substrate profiles of FucT III and FuvT V |
