Macromolecular aspartate aminotransferase

European Journal of Gastroenterology & Hepatology, 1998
Macroenzymes are serum enzymes that have a greater molecular mass than the corresponding enzyme normally found in serum (Klonoff. West J Med 1980; 133: 392-407). Serum AST (aspartate aminotransferase) has rarely been reported to complex with immunoglobulins, resulting in an elevation in serum AST activity.

Aspartate aminotransferase ofLactobacillus murinus

Folia Microbiologica, 1988
Aspartate aminotransferase from Lactobacillus murinus is thermostable, its activity being not changed for two months at temperatures between 4 and -70 degrees C. Maximum activity was observed at 40 degrees C and pH 7.3 in phosphate buffer (30 mmol/L). delta G* Value of 26.3 kJ/mol was calculated from the Arrhenius plot.

Aspartate aminotransferase isoenzymes

Clinical Biochemistry, 1990
Aspartate aminotransferase (AST, EC 2.6.1.1) exists in human tissues as two distinct isoenzymes, one located in the cytoplasm (c-AST), and the other in mitochondria (m-AST). Striated muscle, myocardium, and liver tissues are the main sources of AST. A growing body of information suggests that determination of AST isoenzymes in human serum is useful in ...

Reconstituted aspartate aminotransferase physical studies

Biochimica et Biophysica Acta (BBA) - Enzymology, 1968
Abstract Apo-aspartate aminotransferase ( l -aspartate:2-oxoglutarate aminotransferase, EC 2.6.1.1) from pig heart can be recombined with pyridoxal 5-phosphate to form reconstituted species with properties indistinguishable from those of the original enzyme. Two distinct types of enzyme properties were investigated in these studies.

Inactivation of brain and kidney aspartate aminotransferases by S-(1,2,-dichlorovinyl)-L-cysteine and by S-(1,1,2,2,-tetrafluoroethyl)-L-cysteine.

Developmental Neuroscience, 1996
Long-term exposure to trichloroethylene can cause kidney cancer in experimental animals and humans. In addition, dichloroacetylene (a breakdown product of trichloroethylene) is nephrotoxic and neurotoxic.

Macro-aspartate aminotransferase and pregnancy

European Journal of Gastroenterology & Hepatology, 2004
Macro-aspartate aminotransferase (AST) is a benign condition characterised by unexplained persistent fluctuations f this macroenzyme complex in serum. However, it is not clear what causes this phenomenon or which factors favour its appearance in the blood. Moreaover, it is not known whether normal pregnancy mayinfluence macro-AST levels or whether this

The past and present of serum aminotransferases and the future of liver injury biomarkers

EXCLI Journal : Experimental and Clinical Sciences, 2016
Laboratory testing is important in the diagnosis and monitoring of liver injury and disease. Current liver tests include plasma markers of injury (e.g.
