NCIt definition : A dual function enzyme derived from bacterial Acinetobacter glutaminasificans used
as an adjuvant in chemotherapy. Acinetobacter glutaminase-asparaginase (AGA) possesses
both L-glutaminase and L-asparaginase activities, capable of hydrolyzing glutamine
and asparagine, thereby disturbing nitrogen supplies for dividing cells. When co-administered
with alkylating agent melphalan, which utilizes amino acid transport systems for cellular
uptake, depletion of glutamine by AGA appeared to facilitate melphalan uptake and
enhance its cytotoxicity.;
