| This may occur in part as a result of pathologically elevated activity of arginase, an enzyme that hydrolyzes arginine to ornithine and urea. |
| The gastric ulcer-healing action of allylpyrocatechol is mediated by modulation of arginase metabolism and shift of cytokine balance. |
| A deficiency in one of the enzymes in this pathway causes a urea cycle disorder, and all deficiencies except arginase cause severe hyperammonemia. |
| About 50-percent of ingested arginine is rapidly converted in the body to ornithine, primarily by the enzyme arginase. |
| Another study reported high serum arginase in MDD patients compared with healthy controls. |
