Transaminases in the acquired pellicle
Archives of Oral Biology, 2009Transaminases (AST, aspartate amino transferase; ALT, alanine amino transferase) are relevant enzymes in physiology and pathology of the human organism. The aim of the present in situ study was to demonstrate the presence of these enzymes in the enamel pellicle.Bovine enamel slabs were fixed on buccal sites of individual upper jaw splints and worn for ...

Affinity chromatography of transaminases
Analytical Biochemistry, 1971Abstract It is shown that glutamic-oxaloacetic transaminase from pig heart can be selectively and reversibly bound to a Sepharose column substituted with N′-alkyl derivatives of pyridoxamine 5′-phosphate. A simple procedure is described which includes formation of apotransaminase, its binding to the substituted Sepharose, and its elution under the ...

Combination of the Suzuki-Miyaura Cross-Coupling Reaction with Engineered Transaminases.
Chemistry, 2018The combination of enzymatic and chemical reaction steps is one important area of research in organic synthesis, preferentially as cascade reactions in one-pot to improve total conversion and achieve high operational stability.

Transaminases for Pyridoxamine and Purines
Nature, 1952BRAUNSTEIN'S1 demonstration of the transaminase reaction as a mode of formation of ammo-acids has been broadened recently to include a wide variety of transaminases in bacteria2, animal tissues3 and plants4. In the present communication, we wish to report the formation of compounds other than amino-acids by the transaminase reaction.

Cysteic Acid Transaminase [PDF]
Nature, 1952 IT has previously been reported by Cohen1 that enzyme preparations catalysing the reactions : (1) Alanine + α-ketoglutarate ⇌ glutamate + pyruvate; (2) Aspartate + α-ketoglutarate ⇌ glutamate + oxalo acetate; are also capable of catalysing : (3) Cysteic acid + α-ketoglutarate ⇌ glutamate + sulphopyruvate.

Transaminase in rotavirus gastroenteritis
Pediatrics International, 2012AbstractBackground: Children infected with rotavirus often show increased levels of transaminase, and symptoms are characterized by white stool, similar to biliary atresia. Rotavirus infections are also sporadically accompanied with convulsions, encephalopathy and Reye syndrome.

Since the review on transaminases by Cohen (1951), a large body of information has accumulated on transamination reactions in various organisms. Detailed account of the various transaminases has been given in two reviews by Meister (1955, 1957). The methods used in the study of general transaminases have been reviewed by Aspen and Meister (1958), those

Experimental Cell Research, 1973
Abstract Aspartic transaminase, tyrosine transaminase, lactic dehydrogenase, and glutamic dehydrogenase were studied in Tetrahymena pyriformis in order to gain a better understanding of the control of the entrance and exit of metabolic intermediates to and from the major carbohydrate pathways.

Transaminases in Neurospora crassa
Nature, 1951THE presence of a wide range of transaminases in both animal tissues1 and bacteria2 has recently been reported. A rather similar array of enzymes appears to be present in the mould Neurospora crassa.

In summary, several branched-chain fatty acids appeared to be competitive inhibitors of GABA-T and non-competitive inhibitors of SSADH. These compounds produce an increase in brain GABA level, and for two of these it was shown that the increase differs among various brain areas. An increase of GABA cannot be obtained by inhibition of SSADH.
