Description
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 towards other amine acceptors, such as spermidine and cadaverine. cf. EC 2.5.1.22 (spermine synthase) and EC 2.5.1.23 (sym-norspermidine synthase).
Form
Liquid or lyophilized powder
Storage

aminopropyltransferase; putrescine aminopropyltransferase; spermidine synthetase; SpeE; S-adenosylmethioninamine:putrescine 3-aminopropyltransferase
Reaction
S-adenosyl 3-(methylthio)propylamine + putrescine = S-methyl-5'-thioadenosine + spermidine
