Enzyme Information
2.5.1.16 |
Spermidine synthase.
based on mapping to UniProt Q31QK9
S-adenosyl 3-(methylthio)propylamine + putrescine = 5'-S-methyl- 5'-thioadenosine + spermidine.
-!- The enzymes from the plant Glycine max and from mammalia are highly specific for putrescine as the amine acceptor. -!- The enzymes from the bacteria Escherichia coli and Thermotoga maritima prefer putrescine but are more tolerant toward other amine acceptors, such as spermidine and cadaverine. -!- Cf. EC 2.5.1.22 and EC 2.5.1.23.
