NAD+ [CPD:C00003];
NADP+ [CPD:C00006]
Product
dTDP-4-dehydro-6-deoxy-alpha-D-glucose [CPD:C11907];

H+ [CPD:C00080]
Comment
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].
