bis(3-aminopropyl)amine [CPD:C03375];
CO2 [CPD:C00011];
spermidine [CPD:C00315]
Comment
A pyridoxal 5'-phosphate enzyme. Part of a bacterial polyamine biosynthesis pathway. The enzyme is essential for biofilm formation in the bacterium Vibrio cholerae [1]. The enzyme from Campylobacter jejuni only produces spermidine in vivo even though it shows activity with carboxynorspermidine in vitro [3].
