Abstract
L-asparaginases (L-ASPases) are important bacterial biopharmaceuticals used to treat Acute Lymphoblastic Leukemia (ALL), since this tumor type is dependent of asparagine availability of extracellular asparagine (Asn). Bacterial L-ASPases are able to hydrolyse efficiently Asn in Aspartic acid (Asp) and ammonia (NH3), thus reducing the Asn availability for tumor cells and inducing apoptosis…
