| 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 neurotransmitter | Small peptides used as primary or co transmitters in nerve cells for example FMRF amide, FLRFamide. (18 Nov 1997) |
| 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 receptor | Specific receptor for peptide neurotransmitters. (18 Nov 1997) |

| peptide synthetase | Any enzyme that catalyses the synthesis of peptide bonds, with the hydrolysis of a nucleoside triphosphate. (05 Mar 2000) |
| peptide t | <chemical> N-(n-(n(2)-(n-(n-(n-(n-d-alanyl l-seryl)-l-threonyl)-l-threonyl) l-threonyl)-l-asparaginyl)-l-tyrosyl) l-threonine. Octapeptide sharing sequence homology with HIV envelope protein gp120. It is potentially useful as antiviral agent in aids therapy. The core pentapeptide sequence, ttnyt, consisting of amino acids 4-8 in peptide t, is the HIV envelope sequence required for attachment to the CD4 receptor. Chemical name: L-Threonine, N-(N-(N2-(N-(N-(N-(N-D-alanyl-L-seryl)-L-threonyl)-L-threonyl)-L-threonyl)-L-asparaginyl)-L-tyrosyl)- (12 Dec 1998) |
