Background: L-asparaginase (L-ASNase, L-asparagine amidohydrolase, E.C.3.5.1.1) is an enzyme with wide therapeutic applicability. Currently, the commercialized L-ASNase comes from mesophilic organisms, presenting low specificity to the substrate and limitations regarding thermostability and active pH range. Such factors prevent the maximum performance of the enzyme in different applications. Therefore, extremophilic Read More

Background: Hutchinson-Gilford progeria syndrome (HGPS), also known as progeria of childhood or progeria is a rare, rapid, autosomal dominant genetic disorder characterized by premature aging which occurs shortly after birth. HGPS occurs as a result of de novo point mutation in the gene recognized as LMNA gene that encodes two proteins, Lamin A protein and Lamin C protein which are the structural components of the n Read More

Background: L-Methioninase (EC 4.4.1.11; MGL) is a pyridoxal phosphate (PLP)-dependent enzyme that is produced by a variety of bacteria, fungi, and plants. L-methioninase, especially from Pseudomonas and Citrobacter sp., is considered as the efficient therapeutic enzyme, particularly in cancers such as glioblastomas, medulloblastoma, and neuroblastoma that are more sensitive to methionine starvation. Objective: The lo Read More

Background: Methotrexate (MTX) is a general chemotherapeutic agent utilized to treat a variety of malignancies, woefully, its high doses can cause nephrotoxicity and subsequent defect in the process of MTX excretion. The recombinant form of glucarpidase is produced by engineered E. coli and is a confirmed choice to overcoming this problem. Objective: In the present study, in silico analyses were performed to select suitable S Read More

Background: All parts of Momordica charantia L. have potential hypoglycemic properties in reversing the metabolic disorder of diabetes mellitus. However, there exists a need for preparing an effective and safer formulation of active phytochemicals. We have also reviewed and analyzed certain patents on such preparatory methods for Momordica charantia L. formulations. Objective: This study aimed to isolate essential o Read More
