N-succinylarginine dihydrolase
From Wikipedia, the free encyclopedia
In enzymology, a N-succinylarginine dihydrolase (EC 3.5.3.23) is an enzyme that catalyzes the chemical reaction
- N2-succinyl-L-arginine + 2 H2O N2-succinyl-L-ornithine + 2 NH3 + CO2
Thus, the two substrates of this enzyme are N2-succinyl-L-arginine and H2O, whereas its 3 products are N2-succinyl-L-ornithine, NH3, and CO2.
This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in linear amidines. The systematic name of this enzyme class is N2-succinyl-L-arginine iminohydrolase (decarboxylating). Other names in common use include N2-succinylarginine dihydrolase, arginine succinylhydrolase, SADH, AruB, AstB, and 2-N-succinyl-L-arginine iminohydrolase (decarboxylating). This enzyme participates in arginine and proline metabolism.
