Purification studies of tyrosine-alpha-ketoglutaric acid transaminase.

چکیده
Recent studies in vitro of tyrosine metabolism have revealed the distribution and the r&e of the tyrosine-a-ketoglutaric acid transaminase system (l-8). In certain of these studies the obligatory rBle of this transaminase as a first step in the conversion of tyrosine to homogentisic acid has been indicated (6-S). The present study is concerned with the partial purification of dog liver tyrosine-cr-ketoglutaric acid transaminase and defines some properties of the following reaction system.

Effect of protein intake and cold exposure on selected liver enzymes associated with amino acid metabolism.
The activity of five liver enzymes involved in amino acid metabolism was found to be markedly increased in coldexposed rats. However, the activity of three of the enzymes, arginase, glutamic-oxalacetic and glutamic-pyruvic transaminase, was increased only as a result of a cold-induced higher protein intake. In contrast, the activity of tryptophan pyrrolase and tyrosine alpha ketoglutaric transm...

The purification procedure, some properties and the mode of action of glutamic pyruvic transaminase (GPT) from pig heart muscle have been reported in the pre vious papers (1,2). The presence of GPT and glutamic-oxaloacetic transaminase (GOT) activities in the mitochondrial fraction has been reported by Rosewell (3,4), who qualitatively demonstrated the formation of glutamic acid from ƒ¿-ketoglu...
متن کاملSimultaneous quantitation of alpha-ketoglutaric acid and 5-hydroxymethylfurfural in plasma by HPLC with UV and fluorescence detection.
Alpha-ketoglutaric acid (KG) and hydroxymethylfurfural (HMF) are currently being investigated in clinical trials as an approach in targeted cancer therapy. Hence, a method for the simultaneous determination of KG and HMF in plasma has been developed. Due to the strongly discriminative chemical properties of KG and HMF, SPE purification is performed using an ion-exchange cartridge to separate KG...
متن کاملPurification and properties of halogenated tyrosine and thyroid hormone transaminase from rat kidney mitochondria.
Halogenated tyrosine transaminase has been purified 30-fold from a sonic extract of rat kidney mitochondria. Purification involves ammonium sulfate fractionation and chromatography on diethylaminoethyl cellulose and hydroxylapatite. The purified enzyme is highly specific for tyrosine analogues with halogen substituents in positions 3 or 3 and 5, for thyroid hormones, and, to a lesser extent, fo...
متن کاملTransamination with Purified Enzyme Preparations (transaminase)
Braunstein and Kritzmann (1) have reported that with pigeon breast muscle any a-amino acid, with the possible exception of glycine, is active in transamination with either a-ketoglutaric or oxaloacetic acid. On the other hand, the author (2) found that transamination in pigeon breast muscle is limited to the following reactions. a (1) Z(+)-Glutamic acid + oxaloacetic acid e a-ketoglutaric acid ...
