IUBMB Enzyme Nomenclature


Accepted name: 3,6-anhydro-α-L-galactose dehydrogenase

Reaction: 3,6-anhydro-α-L-galactopyranose + NAD(P)+ + H2O = 3,6-anhydro-L-galactonate + NAD(P)H + H+

Systematic name: 3,6-anhydro-α-L-galactopyranose:NAD(P)+ 1-oxidoredutase

Comments: The enzyme, characterized from the marine bacterium Vibrio sp. EJY3, is involved in a degradation pathway for 3,6-anhydro-α-L-galactose, a major component of the polysaccharides produced by red macroalgae, such as agarose and porphyran.
