- * Arginase and agmatinase signatures *
- **************************************
-
- Arginase (EC 3.5.3.1) catalyzes the degradation of arginine to ornithine and
- urea. The sequence of arginase from several eukaryotes and one prokaryote [1]
- indicates that this enzyme has been well conserved through evolution.
-
- Agmatinase (EC 3.5.3.11) (agmatine ureohydrolase) is a prokaryotic enzyme that
- catalyzes the hydrolysis of agmatine into putrescine and urea [2]. It is
- structurally related to arginase.
-
- Arginase and agmatinase are enzymes of about 300 amino-acid residues. We
- selected two conserved regions as signatures for these types of enzyme.
