Enzyme Information
| 4.1.1.96 | 
							 Carboxynorspermidine decarboxylase. 
							based on mapping to UniProt A8FNH9 		
							(1) Carboxynorspermidine = bis(3-aminopropyl)amine + CO(2). (2) Carboxyspermidine = spermidine + CO(2). 
							-!- Part of a bacterial polyamine biosynthesis pathway. -!- The enzyme is essential for biofilm formation in the bacterium Vibrio cholerae. -!- The enzyme from Campylobacter jejuni only produces spermidine in vivo even though it shows activity with carboxynorspermidine in vitro.
