Rhizobium etli asparaginase II
Bacterial L-asparaginase has been a universal component of therapies for childhood acute lymphoblastic leukemia since the 1970s. Two principal enzymes derived from Escherichia coli and Erwinia chrysanthemi are the only options clinically approved to date. We recently reported a study of recombinant L-asparaginase (AnsA) from Rhizobium etli and described an increasing type of AnsA family members...
متن کاملL-Asparaginase from Erwinia carotovora
The physicochemical properties of the antileukemic Lasparaginase from Erwinia carotovora have been studied and compared with those of the corresponding clinically effective enzyme from Escherichia coli B. Although both enzymes are tetramers with similar molecular weight, the amino acid compositions are distinctly different and the Erwinia enzyme is more basic as judged by polyacrylamide electro...
متن کاملImmunological responses to L-asparaginase.
In a series of 40 patients treated with L-asparaginase for various neoplastic diseases, 6 patients had generalized anaphylactic reactions to L-asparaginase. Each of these reactors had antibodies detectable by passive hemagglutination, but precipitins were detectable in only one of this group of six patients. That patient had received two courses of the enzyme. 1 wk after the anaphylactic reacti...
متن کاملPEG-asparaginase induced severe hypertriglyceridemia.
Asparaginase (ASP) is an effective chemotherapy agent extensively used in children with acute lymphocytic leukemia (ALL). There has been a recent interest in using ASP in adults with ALL, particularly the less toxic pegylated (PEG) formulation. Hypertriglyceridemia (HTG) is a rare complication of PEG-ASP therapy. We report two cases of obese patients who developed severe HTG after receiving PEG...
