3536916-0	1986	In vitro inactivation of methionine synthase by nitrous oxide.	Nitrous Oxide	48-61	5-methyltetrahydrofolate-homocysteine methyltransferase	Homo sapiens	25-44	
3536916-2	1986	Prolonged exposure to N2O leads to megaloblastic anemia in humans and to loss of methionine synthase activity in vertebrates.	Nitrous Oxide	22-25	5-methyltetrahydrofolate-homocysteine methyltransferase	Homo sapiens	81-100	
3536916-3	1986	We now report that purified preparations of cobalamin-dependent methionine synthase (5-methyltetrahydrofolate-homocysteine methyltransferase, EC 2.1.1.13) from both Escherichia coli and pig liver are irreversibly inactivated during turnover in buffers saturated with N2O.	Nitrous Oxide	267-270	5-methyltetrahydrofolate-homocysteine methyltransferase	Homo sapiens	64-83
