Abstract
|
Asparaginase, which is found in various plant, animal and bacterial cells, catalyses the deamination of asparagine to yield aspartic acid and an ammonium ion, resulting in a depletion of free circulatory asparagine in plasma [1]. The enzyme is effective in the treatment of human malignant lymphomas, which have a diminished capacity to produce asparagine synthetase: in order to survive, such cells absorb asparagine from blood plasma [2, 3] - if Asn levels have been depleted by injection of asparaginase, the lymphoma cells die. Glutaminase, a similar enzyme, catalyses the deaminination of glutamine to glutamic acid and an ammonium ion [2]. Both enzymes are homotetramers [1]: two threonine residues in the N-terminal half of the proteins are involved in the catalytic activity.
