Protein

Alanine aminotransferase 1

Gene

Gpt

Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

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 (By similarity).By similarity

Catalytic activityi

L-alanine + 2-oxoglutarate = pyruvate + L-glutamate.
