... were found in the ileum than in the duodenum or jejunum. 3. As had been previously reported for the rat liver, nitrous oxide in vivo reduced the enzyme activity in both the villous and crypt cell populations, suggesting a role in vivo for the enzyme. We conclude that methionine synthetase is both...
