Accepted name: 3-succinoylsemialdehyde-pyridine dehydrogenase
Reaction: 4-oxo-4-(pyridin-3-yl)butanal + NADP+ + H2O = 4-oxo-4-(pyridin-3-yl)butanoate + NADPH + H+
Glossary: 4-oxo-4-(pyridin-3-yl)butanal = 3-succinoylsemialdehyde-pyridine
4-oxo-4-(3-pyridyl)-butanoate = 3-succinoyl-pyridine
Systematic name: 4-oxo-4-(pyridin-3-yl)butanal:NADP+ oxidoreductase
Comments: The enzyme has been characterized from the soil bacterium Pseudomonas sp. HZN6. It participates in the nicotine degradation pathway.
