Agmatinase

In enzymology, an agmatinase (EC 3.5.3.11) is an enzyme that catalyzes the chemical reaction7981475986ENSG00000116771ENSMUSG00000040706Q9BSE5A2AS89NM_024758NM_001081408NP_079034NP_001074877(See Template:Leucine metabolism in humans – this diagram does not include the pathway for β-leucine synthesis via leucine 2,3-aminomutase) In enzymology, an agmatinase (EC 3.5.3.11) is an enzyme that catalyzes the chemical reaction Thus, the two substrates of this enzyme are agmatine and H2O, whereas its two products are putrescine and urea. 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 agmatine amidinohydrolase. Other names in common use include agmatine ureohydrolase, and SpeB. This enzyme participates in urea cycle and metabolism of amino groups. In humans, the enzyme is encoded by the AGMAT gene. As of late 2007, 5 structures have been solved for this class of enzymes, with PDB accession codes 1GQ6, 1GQ7, 1WOG, 1WOH, and 1WOI.
