Exopeptidase Inhibitor

Exopeptidase inhibitors (pronunciation: ex-o-pep-ti-dase in-hi-bi-tors) are a class of enzyme inhibitors that specifically target and inhibit the activity of exopeptidases, a type of protease that cleaves amino acids from the ends of proteins and peptides.

Etymology

The term "exopeptidase inhibitor" is derived from the words "exopeptidase", which refers to the type of enzyme it inhibits, and "inhibitor", which refers to its function of preventing or reducing the activity of the enzyme.

Function

Exopeptidase inhibitors work by binding to the active site of exopeptidases, preventing them from cleaving amino acids from proteins and peptides. This can be useful in a variety of medical and research contexts, such as slowing the progression of certain diseases or studying the function of specific proteins.

Types

There are several types of exopeptidase inhibitors, including:

  • Aminopeptidase inhibitors: These inhibit aminopeptidases, which cleave amino acids from the N-terminus (beginning) of proteins and peptides.
  • Carboxypeptidase inhibitors: These inhibit carboxypeptidases, which cleave amino acids from the C-terminus (end) of proteins and peptides.

Clinical Use

Exopeptidase inhibitors have potential therapeutic applications in a variety of diseases, including cancer, inflammatory diseases, and neurodegenerative diseases. For example, they can be used to inhibit the breakdown of therapeutic peptides, thereby increasing their effectiveness.
