The research described here provides one mechanism of uniting current effects of nitric oxide (NO) with the elevated levels of homocysteine detected in patients with cardiovascular and other disease. Time- and dose-dependent studies of the inhibition

Vitamin B12-dependent methionine synthase is an important enzyme for sulphur amino acid, folate polyamine metabolism, S-adenosylmethionine metabolism and also in the methylation pathway of DNA, RNA, proteins and lipids. Consequently, studies aiming a

Methioninesynthase( L-homocysteine-S-methyltransferase) is a cytosolic enzyme catalysing the formation of methionine and tetrahydrofolate from homocysteine and methyltetrahydrofolate. It is one of two vitamin B,, (cobalamin) dependent enzymes, in mam

0 Vitamin B12dependent methionine synthase has been shown to be inhibited by nitric oxide in a time dependent and dose-dependent manner in vitro [ 11. This enzyme is the first step in decarboxy Sadenosyl methionine (dcSAM) formation and hence should

The in vitro inactivation of methionine synthase (isolated from E. Coli and pig liver) by N,O has already been demonstrated (1). Here we report: (a) The purification to electrophoretic homogeneity of B12-methionine synthase from rat liver to cytosol
