IUBMB Enzyme Nomenclature


Accepted name: glutarate-semialdehyde dehydrogenase

Reaction: 5-oxopentanoate + NADP+ + H2O = glutarate + NADPH + H+

Glossary: 5-oxopentanoate = glutarate semialdehyde

Other name(s): glutarate semialdehyde dehydrogenase; davD (gene name)

Systematic name: glutarate-semialdehyde:NADP+ oxidoreductase

Comments: The enzyme, characterized from multiple Pseudomonas strains, participates in L-lysine degradation. Unlike earlier claims, it prefers NADP+ to NAD+.
