Target Bioclass
Enzyme
Family
Class-I pyridoxal-phosphate-dependent aminotransferase family, Alanine aminotransferase subfamily
Subcellular location
Cytoplasm
Function
Catalyzes the reversible transamination between alanine and 2-oxoglutarate to form pyruvate and glutamate. Participates in cellular nitrogen metabolism and also in liver gluconeogenesis starting with precursors transported from skeletal muscles.
