Accepted name: L-fucose dehydrogenase
Reaction: β-L-fucopyranose + NADP+ = L-fucono-1,5-lactone + NADPH + H+

Systematic name: β-L-fucopyranose:NADP+ 1-oxidoreductase
Comments: The enzyme, characterized from the bacterium Burkholderia multivorans, participates in an L-fucose degradation pathway. The enzyme catalyses the oxidation of β-L-fucopyranose to L-fucono-1,5-lactone, which is unstable and is rapidly converted to L-fucono-1,4-lactone. The α anomer is not recognized. The enzyme can also act on β-L-galactopyranose and D-arabinose with lower activity. NADP+ is a better cosubstrate than NAD+.
