EC 3.4.19.3
Pyroglutamyl-peptidase I (, also known as Pyrrolidonyl peptidase, is an enzyme (a cysteine peptidase) found in bacteria, plants and animals. It can be used to distinguish certain Streptococcal organisms. Other names are ''5-oxoprolyl-peptidase'', ''pyrase'', ''pyrrolidonyl arylamidase'', ''pyroglutamate aminopeptidase'', ''pyroglutamyl aminopeptidase'', ''L-pyroglutamyl peptide hydrolase'', ''pyrrolidone-carboxyl peptidase'', ''pyrrolidone-carboxylate peptidase'', ''pyrrolidonyl peptidase'', ''L-pyrrolidonecarboxylate peptidase'', ''pyroglutamidase'', ''pyrrolidonecarboxylyl peptidase'') is an enzyme. This enzyme catalysis, catalyses the following chemical reaction : Release of an N-terminal pyroglutamyl group from a polypeptide, the second amino acid generally not being Proline, Pro Human gene PGPEP1 See also * Pyrrolidonyl-beta-naphthylamide * P-Dimethylaminocinnamaldehyde * Pyroglutamic acid * 2-Naphthylamine References External links * {{Portal bar, Biology, b ...

Enzyme
An enzyme () is a protein that acts as a biological catalyst by accelerating chemical reactions. The molecules upon which enzymes may act are called substrate (chemistry), substrates, and the enzyme converts the substrates into different molecules known as product (chemistry), products. Almost all metabolism, metabolic processes in the cell (biology), cell need enzyme catalysis in order to occur at rates fast enough to sustain life. Metabolic pathways depend upon enzymes to catalyze individual steps. The study of enzymes is called ''enzymology'' and the field of pseudoenzyme, pseudoenzyme analysis recognizes that during evolution, some enzymes have lost the ability to carry out biological catalysis, which is often reflected in their amino acid sequences and unusual 'pseudocatalytic' properties. Enzymes are known to catalyze more than 5,000 biochemical reaction types. Other biocatalysts include Ribozyme, catalytic RNA molecules, also called ribozymes. They are sometimes descr ...
