متن کاملN5-methyltetrahydrofolate-homocysteine transmethylase. Propylation characteristics with the use of a chemical reducing system and purified enzyme.
A simple method is described whereby millimicromole amounts of extensively purified N5-methyltetrahydrofolatehomocysteine transmethylase (vitamin Blz transmethylase) can be chemically propylated to yield an inhibited vitamin Blz enzyme which is reactivated with light. The procedure consists of a short incubation of the enzyme with propyl iodide in the presence of reduced flavin mononucleotide a...
متن کاملMechanism of decrease in serum folate levels of rats receiving diphenylhydantoin.
Decreased serum folate levels of patients receiving anticonvulsants have been well documented (Klipstein 1964; Reynolds 1968; Dahlke and Mertens-Roeslei 1967; Horwitz et al. 1968; Jensen and Olesen 1969; Houben et al. 1971). At present time, however, the mechanism for this abnormality seems to be remaining unsolved, even though several attractive theories have been advanced, that is, an increas...
متن کاملEffect of 3,4-Methylenedioxymethamphetamine on Liver CYP2C19 Enzyme Activity in Isolated Perfused Rat Liver Using Omeprazole Probe
Background and purpose: This study aimed at investigating the effects of 3,4-Methylenedioxymethamphetamine (MDMA) on liver cytochrome 2C19 enzyme activity, which is a major liver enzyme in the metabolism of a wide range of drugs, using omeprazole as a probe of the CYP2C19 activity in isolated perfused rat liver. Materials and methods: This experimental study was done in 20 male Sprague–Da...
متن کاملEFFECTS OF A VITAMIN Blz DEFICIENCY ON LIVER ENZYMES IN THE RAT*
Certain general functions of vitamin Blz and folic acid in intermediary metabolism are now well recognized. For example, folic acid appears to be involved in purine and formate metabolism and vitamin Blz in the utilization of methyl groups. However, while there have been several reports concerning the influence in viva and in vitro of folic acid and its antagonist, aminopterin, on specific enzy...
