| peptichemio | <chemical> A mixture of six synthetic oligopeptides, each containing melphalan. It is used as a broad-spectrum antineoplastic due to its alkylating and antimetabolic actions but, is toxic to bone marrow, gastrointestinal system and vasculature. Pharmacological action: antimetabolites, antineoplastic, antineoplastic agent, alkylating. Chemical name: Peptichemio (12 Dec 1998) |
|---|---|
| peptidase | <enzyme> Alternative name for a protease. (18 Nov 1997) |
| peptidase D | <enzyme> An enzyme cleaving aminoacyl-l-proline bonds in dipeptides containing a C-terminal prolyl residue; a deficiency of this enzyme results in hyperimidodipeptiduria. Synonym: imidodipeptidase, peptidase D, prolidase. (05 Mar 2000) |
| peptidase P | <enzyme> A hydrolase cleaving C-terminal dipeptides from a variety of substrates, including angiotensin I, which is converted to angiotensin II and histidylleucine. An important step in the metabolism of certain vasopressor agents. It is a chloride-dependent, zinc glycoprotein that is generally membrane-bound and active at neutral pH. Only single dipeptides are released from angiotensin I and bradykinin because of the lack of activity on bonds involving proline. It may also have endopeptidase activity on some substrates. Registry number: EC 3.4.15.1 Synonym: carboxycathepsin, dipeptidyl carboxypeptidase, kinase II, peptidase P. (22 Sep 2002) |
| peptide | <biochemistry> A compound of two or more amino acids where the alpha carboxyl group of one is bound to the alpha amino group of another. (27 Sep 1997) |
| peptide antibiotic lactonase | <enzyme> Peptide lactone and water gives linear peptide Registry number: EC 3.1.1.- (26 Jun 1999) |
| peptide bond | The amide linkage between the carboxyl group of one amino acid and the amino group of another. The linkage does not allow free rotation and can occur in cis or trans configuration, the latter the most common in natural peptides, except for links to the amino group of proline, which are always cis. (18 Nov 1997) |
| peptide chain elongation | The process whereby an amino acid is joined through a substituted amide linkage to a chain of peptides. (12 Dec 1998) |
| peptide chain initiation | The process whereby the formation of a peptide chain is started. This process requires (1) the 30s subunit, (2) the mRNA coding for the polypeptide to be made, (3) met-trnai, (4) initiation factors, and (5) GTP. (12 Dec 1998) |
| peptide chain termination | The process whereby the last amino acid is added to a polypeptide. This termination is signaled by one of three termination triplets in the mRNA, immediately following the last amino acid codon. (12 Dec 1998) |
| peptide deformylase | <enzyme> Fms is a zinc-containing protein showing homologies with zinc aminopeptidases; its enzyme function resembles that of an aminopeptidase; has been sequenced; mol mass 19,207 da Registry number: EC 3.4.11.- Synonym: fms protein, fms gene product (26 Jun 1999) |
| peptide elongation factor tu | A protein found in bacteria and eukaryotic cells which delivers aminoacyl-trna's to the a site of the ribosome. The aminoacyl-trna is first bound to a complex of elongation factor tu containing a molecule of bound GTP. The resulting complex is then bound to the 70s initiation complex. Simultaneously the GTP is hydrolyzed and a tu-GDP complex is released from the 70s ribosome. The tu-GTP complex is regenerated from the tu-GDP complex by the ts elongation factor and GTP. (12 Dec 1998) |
| peptide elongation factors | Protein factors uniquely required during the elongation phase of protein synthesis. (12 Dec 1998) |
| peptide hormone inactivating endopeptidase | <enzyme> From xenopus laevis; cleaves at xaa-phe, xaa-leu or xaa-ile bonds where xaa = ser, phe, tyr, his or gly in peptide hormones Registry number: EC 3.4.24.- Synonym: phie, xenopus (26 Jun 1999) |
| peptide hydrolases | <enzyme> Registry number: EC 3.4 (12 Dec 1998) |
