| 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 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) |
| peptide synthases | <enzyme> Enzymes that catalyze the joining of an acid and an amino acid by the formation of a carbon-nitrogen bond. Registry number: EC 6.3.2. (12 Dec 1998) |
| 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) |
