PEPTIDE PEPTIDOHYDROLASES Meaning and
Definition
-
Peptide peptidohydrolases, also known as peptidases, are a specific class of enzymes involved in the degradation of peptides. These enzymes catalyze the hydrolysis of peptide bonds – the chemical bonds that link amino acids together in a peptide or protein chain. Peptidases play a crucial role in various biological processes, including digestion, protein turnover, and cellular signaling.
In terms of their structure, peptidases are typically globular proteins, composed of one or more polypeptide chains. These chains fold into a three-dimensional structure that contains an active site. The active site is a specific region on the enzyme surface where the peptide substrate binds and undergoes hydrolysis. Different peptidases may have varying substrate specificities, recognizing and cleaving specific peptide bonds based on the amino acid sequence or other chemical properties of the peptide substrate.
Peptide peptidohydrolases are classified into various families based on their similarities in sequence, structure, and catalytic mechanism. Some well-known peptidase families include serine peptidases, cysteine peptidases, metallo peptidases, and aspartic acid peptidases. Each family has its own characteristic features, such as the presence of specific catalytic residues, metal ions, or structural motifs.
Overall, peptide peptidohydrolases are essential enzymes involved in the breakdown of peptides, allowing for the recycling of amino acids and the regulation of protein function within cells. They are found across all domains of life, including animals, plants, and microorganisms, and their diverse functions make them an important focus of research and drug development.

Etymology of PEPTIDE PEPTIDOHYDROLASES
The word "peptide" originates from the Greek word "peptos", which means "digestible" or "dissolvable". It was coined by the German chemist Emil Fischer in 1906. Peptides are short chains of amino acids that are the building blocks of proteins.
"Peptidohydrolases" is a compound word composed of "peptide" and "hydrolases". The term "hydrolase" is derived from the Greek word "hydor", meaning "water", and the suffix "-lase", indicating an enzyme. Hydrolases are enzymes that catalyze the hydrolysis reaction, which involves the breaking of a chemical bond using water.
Therefore, "peptide peptidohydrolases" refers to enzymes that hydrolyze or break down peptides by cleaving the peptide bonds between amino acids using water as a reactant.
