Protein

Serine--pyruvate aminotransferase, mitochondrial

Gene

Agxt

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Dual metabolic roles of gluconeogenesis (in the mitochondria) and glyoxylate detoxification (in the peroxisomes).By similarity

Catalytic activityi

L-serine + pyruvate = 3-hydroxypyruvate + L-alanine.
L-alanine + glyoxylate = pyruvate + glycine.
