Arginase

spinqualitylabelsall models Structure of rat arginase containing Mn+2 (purple) complex with ornithine (cyan) and urea (yellow) (PDB code 1hqg). Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image   Print3D Function Arginase (Arg) catalyzes the conversion of arginine to ornithine and urea. Arg is the final enzyme in the urea cycle. Arg requires 2 manganese ions for functioning. Disease Arg deficiency is an inherited disorder causing the accumulation of toxic urea in the blood. Structural highlights The manganese ions are located at the bottom of a 15A cleft. The proposed reaction mechanism involves H141, D128, E277 in rat.
