Description
The reaction takes place in the opposite direction. Part of a bacterial polyamine biosynthesis pathway. L-aspartate 4-semialdehyde and propane-1,3-diamine/putrescine form a Schiff base that is reduced to form carboxynorspermidine/carboxyspermidine, respectively. The enzyme from the bacterium Vibrio cholerae is essential for biofilm formation. The enzyme from Campylobacter jejuni only produces carboxyspermidine in vivo even though it also can produce carboxynorspermidine in vitro.
Form
Liquid or lyophilized powder
Storage
Store it at +4 ºC for short term. For long term storage, store it at -20 ºC～-80 ºC.
Synonyms
carboxynorspermidine dehydrogenase; carboxyspermidine dehydrogenase; CASDH; CANSDH; VC1624 (gene name)
Reaction
(1) carboxynorspermidine + H2O + NADP+ = L-aspartate 4-semialdehyde + propane-1,3-diamine + NADPH + H+; (2) carboxyspermidine + H2O + NADP+ = L-aspartate 4-semialdehyde + putrescine + NADPH + H+
