1.4.1.B4 | L-aspartic 4-semialdehyde + 1,3-diaminopropane + NADPH + H+ = carboxynorspermidine + NADP+ + H2O |
i.e. (3-((3-aminopropyl)amino)propyl)carbamate (carboxynorspermidine) and (2S)-2-amino-4-oxobutanoate (L-aspartic 4-semialdehyde) via a nicotinamide-nucleotide reduction of the Schiff base H2N(CH2)3=CHCH2CH(NH2)COOH, formed from L-aspartic beta-semialdehyde, an intermediate in the novel pathway for norspermidine biosynthesis |
