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.

Loss of Life Expectancy by 10 Years or More From Elevated Aspartate Aminotransferase: Finding Aspartate Aminotransferase a Better Mortality Predictor for All-Cause and Liver-Related than Alanine Aminotransferase.

American Journal of Gastroenterology, 2019
OBJECTIVES Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) are 2 commonly ordered liver function tests, and ALT has long been considered more liver-specific than AST. Between the 2, the one which is better in predicting liver or

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.

Measurement of Aminotransferases: Part 1. Aspartate Aminotransferase

CRC Critical Reviews in Clinical Laboratory Sciences, 1984
Aminotransferases are ubiquitous enzymes of mammalian cells and several are of important diagnostic use. The application of aspartate aminotransferase activity measurements in serum from individuals suffering from myocardial infarction brought about a new dimension in clinical laboratory testing in the 1950s.

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 ...

Evolutionary analysis of aspartate aminotransferases

Journal of Molecular Evolution, 1995
Aspartate aminotransferase isoenzymes are located in both the cytosol and organelles of eukaryotes, but all are encoded in the nuclear genome. In the work described here, a phylogenetic analysis was made of aspartate aminotransferases from plants, animals, yeast, and a number of bacteria.
