Effects of Vitamin B6 on the Brain Glutamate Pyrovate Transaminase and Glutamate Oxaloacetate Transaminase in Young and Old Rats
Excessive amounts of extracellular glutamate in brain are excitotoxic and lead to neuronal death. Glutamate pyrovate transamiase (GPT) and glutamate oxaloacetate transaminase (GOT) catalyze transamination of glutamate to alpha ketoglutarate. Because vitamin B6 is essential for the enzymes activities, this study was undertaken to examine the effect of vitamin B6 on age related changes of this en...
متن کاملDffluoro-oxaloacetate with Aspartate Transaminase
Difluoro-oxaloacetate interacts with the aldimine form of aspartate transaminase to give a complex, the dissociation constant ofwhich has been determined spectrophotometrically and by 19F n.m.r. (nuclear magnetic resonance). The 19F n.m.r. line-width-pH and chemical-shift-pH profiles of difluoro-oxaloacetate in the presence of the aldimine form of the enzyme both show inflexion points in the pH...
متن کاملAsparaginase and asparagine transaminase in soybean leaves and root nodules.
Asparaginase activity (</=1 mumol/mg protein . hr) was detected in extracts of soybean (Glycine max [L.] Merr.) leaf blades, but, even after efforts to optimize extraction and assay of the enzyme, specific activity was not sufficient to metabolize the estimated amount of asparagine translocated to leaves. Asparagine transaminase activity with glyoxylate or pyruvate was at least 52 and 62 nmol/m...
متن کاملGlutamate oxaloacetate transaminase (got) genetics in the mouse: polymorphism of got-1.
We have examined a polymorphism for the soluble glutamate oxaloacetate (GOT-1) isozyme system which was found in the Asian mouse Mus castaneus. Variants of GOT-1 segregate as though they are controlled by codominant alleles for a single autosomal locus which we have designated Got-1. No close linkage of genes for soluble and mitochondrial forms of the enzyme, GOT-1 and GOT-2 respectively, was o...
