Glossary: spermidine
Other name(s): glutathionylspermidine amidohydrolase (spermidine-forming)
Systematic name: γ-L-glutamyl-L-cysteinyl-glycine:spermidine amidase
Comments: spermidine is numbered so that atom N-1 is in the amino group of the aminopropyl part of the molecule. The enzyme from Escherichia coli is bifunctional and also catalyses the glutathionylspermidine synthase (EC 6.3.1.8) reaction, resulting in a net hydrolysis of ATP.
