Identification of the gene responsible for the cblB complementation group of vitamin B12-dependent methylmalonic aciduria.
The methylmalonic acidurias are metabolic disorders resulting from deficient methylmalonyl-CoA mutase activity, a vitamin B(12)-dependent enzyme. We have cloned the gene for the cblB complementation group caused by deficient activity of a cob(I)alamin adenosyltransferase. This was accomplished by searching bacterial genomes for genes in close proximity to the methylmalonyl-CoA mutase gene that ...
متن کاملXanthurenic Acid in Depression
An altered or increased excretion of xanthurenic acid (XA) in urine for 24h after intake of 5 grams L-tryptophan (Trp) at 10:00 p.m. is considered a measure of strain in the organism. XA was studied in 104 hospitalized depressive patients (DSM-HI : 296.23; 296.33) and 15 controls. Zung anxiety and depression scales were rated. The XA-excretion after Trp load has a wider range than the blank XA-...
متن کاملKynurenine metabolism and xanthurenic acid formation in vitamin B6-deficient rat after tryptophan injection.
Normal and vitamin B6-deficient rats received an intraperitoneal injection of 30 mg/100g of body wt, and the contents of metabolites in kidney or plasma and the related enzyme activities in kidney were determined. The contents of kynurenine and 3-hydroxykynurenine in B6-deficient rat plasma and kidney were much higher than those in normal rat. The changes of those contents in plasma were parall...
متن کاملPhotoinduced tautomeric transformations of xanthurenic acidw
The properties of xanthurenic acid (XAN) in ground and photoexcited states have been studied using steady-state and time-resolved optical methods as well as quantum chemistry calculations. In neutral aqueous solution and in alcohols, XAN is present in a single tautomeric form (keto form), whereas in aprotic solvents and probably in basic aqueous solutions, more than one tautomeric form is prese...
