Asparaginase Escherichia coli

Asparaginase derived from Escherichia coli (L-asparagine amidohydrolase, EC 3.5.1.1) is an enzyme responsible for the metabolism of L-asparagine, by catalyzing L-asparagine into L-aspartic acid and ammonia. It also facilitates the production of oxaloacetate which is needed for general cellular metabolism. Asparaginase from E. coli has clinically shown to exhibit antitumor actions in models of leukaemias . L-asparaginase of E. coli is marketed under several different trade names, including Elspar, for the treatment of acute lymphoblastic leukemia (ALL) as part of a multi-agent chemotherapeutic regimen. It is available as intramuscular or intravenous injections. Therapeutic L-asparaginase from E. coli works by depleting the levels of non-essential amino acid, asparagine, in lymphoblastic leukemic cells thus promoting apoptotic cell death . For patients who develop hypersensitivity to E. coli-derived formulations of L-asparaginase, the use of PEGylated or non-PEGylated Asparaginase Erwinia chrysanthemi is recommended .
