| 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) |
| peptide map | Proteases will produce fragments of a characteristic size from a protein and this can be used as a test for the identity or otherwise of two similar sized proteins. It is possible to produce a peptide fragment map from a single gel band. (18 Nov 1997) |
| peptide mapping | Two-dimensional separation and analysis of peptides. (12 Dec 1998) |
| peptide N-alpha acetyltransferase | <enzyme> Pituitary enzyme; acetylates peptide hormones including acth; also found in saccharomyces cerevisiae Registry number: EC 2.3.1.88 Synonym: peptide acetyltransferase, acth acetyltransferase, beta-endorphin acetyltransferase, alpha-msh acetyltransferase (26 Jun 1999) |

| peptide peptidohydrolases | <enzyme> A subclass of enzymes of the hydrolase class that catalyses the hydrolysis of peptide bonds. These comprise the exopeptidases and endopeptidases, also called peptide hydrolase. Registry number: EC 3.4.- (12 Dec 1998) |
| peptide permease | <chemical> In candida albicans Chemical name: permease, peptide, (oc-6-63)- Synonym: peptide transport system (26 Jun 1999) |
| peptide phi | A 27-amino acid peptide with histidine at the n-terminal and isoleucine amide at the c-terminal. The exact amino acid composition of the peptide is species dependent. The peptide is secreted in the intestine, but is found in the nervous system, many organs, and in the majority of peripheral tissues. It has a wide range of biological actions, affecting the cardiovascular, gastrointestinal, respiratory, and central nervous systems. (12 Dec 1998) |
| peptide receptor | Specific receptor for peptide neurotransmitters. (18 Nov 1997) |
