摘要：

Cystathionine beta synthase (CBS) deficiency is a metabolic disorder that is biochemically characterized by severe hyperhomocysteinemia. in order to show the effects of CBS deficiency onto the activity of the enzymes involved in the remethylation pathway, we used the well characterized genetic model of severe hyperhomocysteinemia in mice. We showed that CBS deficiency in mice reduced hepatic methionine synthase and betaine-homocysteine methyltransferase activities, whereas 5,10-methylene tetrahydrofolate reductase activity was increased.
