| receptors, peptide | Cell surface receptors that bind peptide messengers with high affinity and regulate intracellular signals which influence the behaviour of cells. (12 Dec 1998) |
|---|---|
| receptors, vasoactive intestinal peptide | Cell surface proteins that bind vasoactive intestinal peptide (vip) with high affinity and trigger intracellular changes which influence the behaviour of cells. (12 Dec 1998) |
| glutaminyl-peptide cyclotransferase | <enzyme> Catalyses the formation of 5-oxoprolyl-trna and nh3 from l-glutaminyl-trna; also acts on glutaminyl peptides Registry number: EC 2.3.2.5 Synonym: glutaminyl cyclase, glutaminylpeptide cyclase, glutamine cyclotransferase, glutaminyl-trna cyclotransferase (26 Jun 1999) |
| 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 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 factors | Protein factors uniquely required during the elongation phase of protein synthesis. (12 Dec 1998) |
| 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.

| 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) |
| peptide initiation factors | Protein factors uniquely required during the initiation phase of protein synthesis. (12 Dec 1998) |
| peptide library | A collection of cloned free peptides, frequently consisting of all possible combinations of amino acids making up an n-amino acid peptide. (12 Dec 1998) |
