IUBMB Enzyme Nomenclature


Accepted name: 2-oxoglutaramate amidase

Reaction: 2-oxoglutaramate + H2O = 2-oxoglutarate + NH3

Glossary: 2-oxoglutaramate = 2-ketoglutaramate = 5-amino-2,5-dioxopentanoate

Other name(s): ω-amidase (ambiguous)

Systematic name: 5-amino-2,5-dioxopentanoate amidohydrolase

Comments: The enzyme, which is highly specific for its substrate, participates in the nicotine degradation pathway of several Gram-positive bacteria.
