D factor
| diabetes related peptide | <hormone, protein> Peptide of 37 amino acids that selectively inhibits insulin stimulated glucose uptake in muscle. Structurally related to calcitonin gene-related peptide. (15 Oct 1997) |
|---|---|
| insulin c-peptide | <investigation> A blood test which measures the amount of C-peptide in the blood. C-peptide is a byproduct of normal insulin production by the beta cells in the pancreas. Normal values are 0.5 to 3.0 ng/ml. Normal levels indicate that the body is still producing its own insulin. Low levels indicate that the pancreas is producing little or no insulin. Elevations can be seen in cases of insulinomas and islet of Langerhans tumours. (27 Sep 1997) |
| insulin-stimulating peptide | <chemical> 71-amino acid containing peptide; corresponds to residues 115-143 and 144-184 of bovine serum albumin with the exception of a tyrosine insertion between residues 155 and 156; consists of two chains with mw 5000 and 3400 for each chain Synonym: h-isp, insulin-stimulating protein (05 Dec 1998) |
| islet amyloid peptide | <hormone, protein> Peptide of 37 amino acids that selectively inhibits insulin stimulated glucose uptake in muscle. Structurally related to calcitonin gene-related peptide. (15 Oct 1997) |
| eosinophil chemotactic peptide | <protein> Tetrapeptides (of which two are identified: VGSE and AGSE) released by mast cells and that are said to both attract and activate eosinophils. (18 Nov 1997) |
| UDP-N-acetylglucosamine-peptide beta-N-acetylglucosaminyltransferase | <enzyme> Responsible for the addition of o-linked n-acetylglucosamine to proteins Registry number: EC 2.4.1.- Synonym: udp-glcnac-peptide-glcnac-transferase, glcnac transferase (26 Jun 1999) |
| formyl peptide | <biochemistry> Informal term for small peptides with a formylated N terminal methionine and usually a hydrophobic amino acid at the carboxy terminal end (fMetLeuPhe is the most commonly used). These peptides stimulate the motor and secretory activities of leucocytes, particularly neutrophils and monocytes, that have a specific receptor (about 60 kD) of high affinity (Kd approximately 10exp 8M). Leucocytes show chemotaxis towards formyl peptides but the term chemotactic peptides understates the range of activities the molecules will trigger. Thought to be synthetic analogues of bacterial signal sequences though this is unproven. The leucocytes of many animals (e.g. Pig, cow, chicken) do not respond. (18 Nov 1997) |
| leader peptide | <molecular biology> In the regulation of gene expression for enzymes concerned with amino acid synthesis in prokaryotes, the leader sequence codes for the leader peptide that contains several residues of the amino acid being regulated. Transcription is closely linked to translation and if translation is retarded by limited supply of amino acyl tRNA for the specific amino acid, the mode of transcription of the leader sequence permits full transcription of the operon genes, otherwise complete transcription of the leader sequence prematurely terminates transcription of the operon. (18 Nov 1997) |
| lysergyl peptide synthetase | <enzyme> Multifunctional enzyme which forms non-cyclol d-lysergyl peptide lactams; consists of two polypeptide chains - lps 1 binds the 3 amino acids (ala, phe and pro) of the peptide nucleus and lps 2 binds d-lysergic acid Registry number: EC 6.3.2.- Synonym: d-lysergylpeptide synthetase (26 Jun 1999) |
| accelerator factor | <chemical> Heat- and storage-labile plasma glycoprotein which accelerates the conversion of prothrombin to thrombin in blood coagulation. Factor v accomplishes this by forming a complex with factor xa, phospholipid, and calcium (prothrombinase complex). Deficiency of factor v leads to owren's disease. Chemical name: Blood-coagulation factor V (12 Dec 1998) |
| acetate replacement factor | <biochemistry> 1,2 dithiolane 3 valeric acid. Regarded as a coenzyme in the oxoglutarate dehydrogenase complex of the citric acid cycle. Involved generally in oxidative decarboxylations of _ keto acids. A growth factor for some organisms. (18 Nov 1997) |
| adrenal weight factor | A postulated substance of adenohypophysial origin responsible for maintenance of the weight of the adrenal cortex. (05 Mar 2000) |
| adrenocorticotropic releasing factor | Hormone produced by hypothalamus that causes pituitary to secrete adrenocorticotropic hormone. (05 Mar 2000) |
| a-factor | <molecular biology> A protein which is found in the bacterial genus Streptomyces that helps start the production of streptomycin and the process of morphological differentiation. It is used in biotechnology to induce these functions in mutant strains of Streptomyces that cannot produce it themselves. (09 Feb 1998) |
| angiogenesis factor | Substance causing proliferation of new blood vessels. It is found in tissues with high metabolic requirements, such as the retina, and in certain cancers. The factor is also released by hypoxic macrophages at the edges or outer surfaces of wounds and initiates revascularization in wound healing. (12 Dec 1998) |
