Carboxynorspermidine synthase (EC 1.5.1.43, carboxynorspermidine dehydrogenase, carboxyspermidine dehydrogenase, CASDH, CANSDH) is an enzyme with systematic name carboxynorspermidine:NADP+ oxidoreductase.[1][2][3] This enzyme catalyses the following chemical reactions

(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+

The reaction takes place in the opposite direction.
