Malate dehydrogenase (MDH) is an important enzyme in an organism’s metabolic pathways. MDH is found in almost all living cells and catalyzes the conversion of malate to oxaloacetate which also involves nicotinamide dehydrogenase (NAD) as a coenzyme. A method to study how an enzyme operates is to alter one of its amino acids and compare the activity of the enzyme before and after the mutation. As a class project in Advanced Biochemistry during the spring semester of 2018, we are working as a team to propose and carry out a point-based mutation on MDH.

Ninety percent of pancreatic cancers are attributed to mutations in the Ras protein, making it paramount to concentrate on Ras activity. This study focuses on Ras activity by targeting a post-translational modifying enzyme of Ras called Isoprenylcysteine carboxyl methyltransferase (Icmt). Elucidation of the binding site of Icmt will allow the development of therapeutics that effectively inhibit Icmt causing the mislocalization of Ras, and in turn, aid in the treatment of Ras driven cancers. Currently, the hydrophobic substrate binding site of Icmt is unknown. In order to characterize the substrate binding site of Icmt, site-directed mutagenesis was used to design mutations …
