What is the Origin of Peptidase Activity?

The study of protein and peptide breakdown began with early biochemistry in the late 19th century, with the specific term "peptidase" denoting the enzyme class that acts on peptides. The understanding of their precise roles in hormonal processing, such as the activation and inactivation of insulin and incretins, solidified in the mid-20th century.

What is the Mechanism of Peptidase Activity?

The mechanism involves the peptidase enzyme binding to a specific recognition sequence on the peptide substrate, followed by the hydrolysis of the peptide bond, effectively terminating or initiating the peptide's biological signal. For example, the enzyme dipeptidyl peptidase-4 (DPP-4) rapidly degrades the incretin hormone GLP-1, thereby limiting its action on glucose homeostasis. Modulating peptidase activity is a proven therapeutic strategy to prolong the half-life and efficacy of therapeutic peptides.

Peptidase Activity

Meaning

Peptidase Activity refers to the biological function of a class of enzymes, also known as proteases, that catalyze the cleavage of peptide bonds within proteins and smaller peptide chains. This enzymatic activity is absolutely critical in endocrinology for several key processes, including the final activation of prohormones into their biologically active hormone forms and the subsequent breakdown and metabolic clearance of circulating peptide hormones. Alterations in this enzymatic function can dramatically impact the bioavailability and signal duration of vital regulatory peptides.
