3-Succinoylsemialdehyde-pyridine dehydrogenase

3-Succinoylsemialdehyde-pyridine dehydrogenase is an enzyme with systematic name 4-oxo-4-(pyridin-3-yl)butanal:NADP+ oxidoreductase. This enzyme catalyses the following chemical reaction


 * 4-oxo-4-(pyridin-3-yl)butanal + NADP+ + H2O $$\rightleftharpoons$$ 4-oxo-4-(pyridin-3-yl)butanoate + NADPH + H+

The enzyme has been characterized from the soil bacterium Pseudomonas sp. HZN6.
