Introduction

Orotidine monophosphate decarboxylase (ODCase), also known as orotidine 5’-monophosphate decarboxylase (OMP decarboxylase) or orotidine 5’-phosphate decarboxylase is an enzyme involved in pyrimidine biosynthesis. It catalyzes the conversion of orotidine 5’-monophosphate (OMP) to uridine 5’-monophosphate (UMP). This reaction is the final step in de novo pyrimidine nucleotide synthesis and is an essential precursor for both DNA and RNA. The main structure of orotidine monophosphate decarboxylase is a TIM barrel, with one side acting as the binding site, while the other side is closed-off. This enzyme has been studied for it’s extreme catalytic proficiency[1].
