Function
L-asparaginase is an enzyme that converts L-asparagine into asparctic acid and ammonia. In adition this enzyme have a side activity analogous to previous one, which is the catalysis of D-glutamine into glutamate and ammonia.
Disease
Lymphoblastic Acute Leukemia, is a blood cancer that affects mainly childs (2-5 age); consists of non-controled proliferation of lymphocytic lineages since lymphoblasts to younges lymphocitic cells.
Relevance
Cancer cells are unable to perform synthesis of L-asparagine due to the lack of Asparagine Synthetase enzyme, which means that all source of L-asparagine is exogenous, unlike normal cells that can synthesize their own L-asparagine. When bacterial L-asparaginase is injected into the bloodstream, circulating L-asparagine is depleted, so cancer cells become unable to perform protein synthesis, that leads affected cells to apoptosis without harm to normal cells.
