“Since the esterase activity of albumin is also inhibited by diisopropylfluorophosphate , and since it is known that diisopropylfluorophosphate covalently binds to Tyr 411 of human albumin, we conclude that the active site for aryl acylamidase activity of albumin is Tyr 411.”
“We found that albumin had aryl acylacylamidase activity and that this activity was inhibited by diisopropylfluorophosphate.”
