| Product Name | spermidine synthase |
| Example Structure |  |
| Synonyms | aminopropyltransferase, aminopropyltransferase spermidine synthase, MdSPDS1, PAPT, PgSPD, putrescine aminopropyltransferase, Spd synthase, SPDS, SPDS2, SPDSYN, spe-sdh, spe3, SpeE, spermidine synthase, spermidine synthase 1, spermidine synthetase, Spm synthase, SpSyn, synthase, spermidine |
| EC Number | 2.5.1.16 |
| CAS Registry Number | 37277-82-0 |
| Comments | The enzymes from the plant Glycine max and from mammalia are highly specific for putrescine as the amine acceptor [2,7]. The enzymes from the bacteria Escherichia coli and Thermotoga maritima prefer putrescine but are more tolerant towards other amine acceptors, such as spermidine and cadaverine [5,6]. cf. EC 2.5.1.22 (spermine synthase) and EC 2.5.1.23 (sym-norspermidine synthase). |
