PROCARBOXYPEPTIDASE U Meaning and
Definition
-
Procarboxypeptidase U is an enzyme that belongs to the class of carboxypeptidases, specifically those acting on peptides with a free C-terminus. It is an inactive precursor enzyme that needs to be activated in order to exhibit its catalytic activity on protein substrates.
Procarboxypeptidase U is synthesized in the pancreas as an inactive zymogen or proenzyme, also known as pancreatic procarboxypeptidase B. It is secreted into the pancreatic juice and is subsequently activated by the enzyme trypsin in the small intestine. The activated form, known as carboxypeptidase B, then participates in the digestion of food proteins in the intestine.
The main function of procarboxypeptidase U is the removal of amino acids from the carboxy terminus of polypeptide chains. It cleaves the C-terminal amino acid residue with high specificity, contributing to the regulation of protein function and stability. It is involved in the breakdown of proteins into smaller peptides and amino acids, allowing for their absorption and utilization by the body.
In addition to its role in digestion, procarboxypeptidase U has also been implicated in other physiological processes, such as blood clotting and tissue regeneration. It exhibits regulatory functions in the development and maintenance of various tissues, as well as in modulating immune responses and inflammation.
Overall, procarboxypeptidase U represents a crucial enzyme involved in protein digestion and numerous biological processes, serving to maintain protein homeostasis and contribute to overall health.

Etymology of PROCARBOXYPEPTIDASE U
The word "Procarboxypeptidase U" is primarily derived from three parts: "Pro-", "carboxy-", and "peptidase".
1. "Pro-" is a prefix derived from Greek, meaning "before" or "in front of". It is used to indicate that the substance in question is an inactive or precursor form that needs to be activated.
2. "Carboxy-" is also derived from Greek, representing the carboxyl group (-COOH) in chemistry. In this context, it refers to the enzyme's ability to cleave carboxyl groups from peptides or proteins.
3. "Peptidase" is a term derived from the combination of "peptide" and the suffix "-ase", which indicates an enzyme. A peptidase is an enzyme responsible for breaking down peptides into smaller units called amino acids.
