Domain Context

CATH Clusters

Superfamily	endopeptidase domain like (from Nostoc punctiforme)
Functional Family	Bifunctional glutathionylspermidine synthetase/amidase

Enzyme Information

3.5.1.78	Glutathionylspermidine amidase. based on mapping to UniProt P0AES0 Glutathionylspermidine + H(2)O = glutathione + spermidine. -!- Transforms glutathionylspermidine into glutathione and spermidine. -!- The enzyme from Escherichia coli is bifunctional and also catalyzes the reaction of EC 6.3.1.8, resulting in a net hydrolysis of ATP.
6.3.1.8	Glutathionylspermidine synthase. based on mapping to UniProt P0AES0 Glutathione + spermidine + ATP = glutathionylspermidine + ADP + phosphate. -!- Involved in the synthesis of trypanothione in trypanosomatids. -!- The enzyme from Escherichia coli is bifunctional and also catalyzes the EC 3.5.1.78 reaction, resulting in a net hydrolysis of ATP.
