Aminotransferases (Transaminases)

Aminotransferases (Transaminases)

Aminotransferases (transaminases) are enzymes that catalyze a transamination reaction between amino acids and α-keto acids. They mainly include glutamate-pyruvate transaminase (GPT), also known as alanine aminotransferase (ALT), and glutamate-oxaloacetate transaminase (GOT), also known as aspartate aminotransferase (AST). Aminotransferases (transaminases) play a crucial role in the biosynthesis of non-essential amino acids, helping cells generate the required amino acids by transferring amino groups. Aminotransferases (transaminases) are also involved in the nitrogen-containing compounds metabolism, converting amino acids into forms that are easily excreted or can be used in other metabolic pathways. ALT and AST are often used as clinical diagnostic indicators. An increase in their levels in the blood is often associated with liver diseases such as hepatitis and cirrhosis, heart diseases such as myocardial infarction, and muscle diseases such as polymyositis[1][2].

    Dioctyl phthalate
    		Activator 99.40%
    Dioctyl phthalate (DNOP) is a plasticizer. Dioctyl phthalate increases the activities of alanine aminotransferase (ALT) and alkaline phosphatase (ALP) in the liver, as well as the levels of creatinine and urea in the kidney. Exposure to Dioctyl phthalate disrupts the homeostasis of the intestinal microbial community, increases the abundance of pathogenic bacteria, and reduces the abundance of beneficial bacteria such as Lactobacillus. Dioctyl phthalate induces significant and dose-dependent inflammatory responses in the liver, spleen and kidney of mice.

    Aspartate aminotransferase (EC 2.6.1.1), Human liver is a metabolic regulator with the highest activity in the heart, liver and skeletal muscle. Aspartate aminotransferase, Human liver comprises two isozymes: the cytoplasmic form (AST1) and the mitochondrial form (AST2). By catalyzing reversible transamination reactions between oxaloacetate, L-glutamate and other substances, it is deeply involved in key physiological processes such as amino acid metabolism, the tricarboxylic acid cycle and neurotransmitter synthesis. Aspartate aminotransferase, Human liver also provides substrate support for the synthesis of urea and purines/pyrimidines. Aspartate aminotransferase, Human liver is a serum marker reflecting cardiac and hepatic injury, and its abnormal levels are also closely associated with myocardial infarction, cardiovascular diseases and various cancers.
