IUBMB Enzyme Nomenclature


Accepted name: deaminated glutathione amidase

Reaction: N-(4-oxoglutaryl)-L-cysteinylglycine + H2O = 2-oxoglutarate + L-cysteinylglycine

Glossary: N-(4-oxoglutaryl)-L-cysteinylglycine = deaminated glutathione

Other name(s): dGSH deaminase; NIT1 (gene name)

Systematic name: N-(4-oxoglutaryl)-L-cysteinylglycine amidohydrolase

Comments: The enzyme, present in animals, fungi and bacteria, is involved in clearing cells of the toxic compound deaminated glutathione, which can be produced as an unwanted side product by several transaminases.
