1.5.99.6 |
Accepted name: |
spermidine dehydrogenase |
Reaction: |
spermidine + acceptor + H2O = propane-1,3-diamine + 4-aminobutanal + reduced acceptor |
Glossary: |
spermidine = N-(3-aminopropyl)butane-1,4-diamine |
Other name(s): |
spermidine:(acceptor) oxidoreductase |
Systematic name: |
spermidine:acceptor oxidoreductase |
Comments: |
A flavohemoprotein (FAD). Ferricyanide, 2,6-dichloroindophenol and cytochrome c can act as acceptor. 4-Aminobutanal condenses non-enzymically to 1-pyrroline. |
