The enzymes from the Gram-negative bacteria Aggregatibacter actinomycetemcomitans and Escherichia coli O52 are involved in activation of fucose for incorporation into capsular polysaccharide O-antigens [1,3]. The enzyme from the Gram-positive bacterium Anoxybacillus tepidamans (Geobacillus tepidamans) is involved in activation of fucose for incorporation into the organism’s S-layer . The enzyme from Escherichia coli O52 has a higher catalytic efficiency with NADH than with NADPH .
The enzyme appears in viruses and cellular organisms

dTDP-alpha-D-fucopyranose:NAD(P)+ oxidoreductase
The enzymes from the Gram-negative bacteria Aggregatibacter actinomycetemcomitans and Escherichia coli O52 are involved in activation of fucose for incorporation into capsular polysaccharide O-antigens [1,3]. The enzyme from the Gram-positive bacterium Anoxybacillus tepidamans (Geobacillus tepidamans) is involved in activation of fucose for incorporation into the organism's S-layer [2]. The enzyme from Escherichia coli O52 has a higher catalytic efficiency with NADH than with NADPH [3].
The dTDP-4-dehydro-6-deoxyglucose reductase encoding fcd gene is part of the surface layer glycoprotein glycosylation gene cluster of Geobacillus tepidamans GS5-97T
