Reaction of the aminic form of aspartate transaminase with difluoro-oxaloacetate

Dffluoro-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...

Interaction between beta-fluoro-oxaloacetate and glutamate-aspartate transaminase of heart mitochondria.

Interaction between p-Fluoro-oxaloacetate and Glutamate- Aspartate Transaminase of Heart Mitochondria”

In a previous publication (1) we have described the synthesis and chemical properties of /3-fluoro-oxaloacetic acid. This acid was found to be a potent inhibitor of mitochondriil malic dehydrogenase (1,2). It is probable that fluoro-oxaloacetate inhibits other enzymes which react with oxaloacetate. We have performed further experiments in order to test this hypothesis. As a part of this study t...

the evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology

abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
