IUBMB Enzyme Nomenclature


Accepted name: 2-dehydro-3-deoxy-L-galactonate 5-dehydrogenase

Reaction: 2-dehydro-3-deoxy-L-galactonate + NAD+ = 3-deoxy-D-glycero-2,5-hexodiulosonate + NADH + H+

Systematic name: 2-dehydro-3-deoxy-L-galactonate:NAD+ 5-oxidoreductase

Comments: The enzyme, characterized from agarose-degrading bacteria, is involved in a degradation pathway for 3,6-anhydro-α-L-galactopyranose, a major component of the polysaccharides of red macroalgae.
