| 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) |
| ABO blood group | <haematology> The major human blood type system which describes the oligosaccharide glycoprotein antigens found on the surface of human blood cells. According to the type of antigen present, a person may be assigned a blood type of A, B, AB or O. A second type of antigen, the Rh factor, renders a positive or negative blood type. The ABO blood group system is important because it determines who can donate blood to or accept blood from whom. Type A or AB blood will cause an immune reaction in people with type B blood and type B and AB blood will cause a reaction in people with type A blood. Conversely, type O blood has no A or B antigens, so people with type O blood are universal donors. And since AB blood already produces both antigens, people who are type AB can accept any of the other blood types without suffering an immune reaction. (04 Jul 1999) |
| actinobacteria group | A group of gram-positive, heterogeneous bacteria. This group encompasses a range of morphologically, physiologically, and chemically different organisms and includes bacteria that form cocci, short rods, irregular rods, and mycelia that fragment. (12 Dec 1998) |
| alkyl group | <chemistry> A funtional group on an organic molecule which is derived from an alkane which has lost a hydrogen atom. (13 Nov 1997) |
| aluminum group | Aluminum, boron, gallium, indium, and thallium. (05 Mar 2000) |
| amino group | <biochemistry> An -NH2 group. Organic compounds which have this group are called amines. (09 Oct 1997) |
| anterior group of axillary lymph nodes | Lymph nodes located along the lateral thoracic vein; they receive the drainage of the pectoral region, including most of the drainage of the breast. Synonym: nodi lymphatici axillaris pectorales, anterior group of axillary lymph nodes. (05 Mar 2000) |
| apical group of axillary lymph nodes | The group of lymph node's located at the apex of the axillary fossa that receive lymphatic drainage from other groups of axillary node's and then drain in turn into the subclavian lymphatic trunk. Synonym: nodi lymphatici axillares apicales. (05 Mar 2000) |
| Bethesda-Ballerup Group | A group of citrate-utilizing, slow lactose-fermenting bacteria (family Enterobacteriaceae) which share a similar series of antigens with the lactose-fermenting citrobacters; these organisms are now included in the genus Citrobacter without a distinction between prompt and slow lactose fermentation. (05 Mar 2000) |
| blood group | <haematology> An inherited feature on the surface of the red blood cell. A series of related blood groups make up a blood group system such as the ABO system or the Rh system. Erythrocytic allotypes (or phenotypes) defined by one or more cellular antigenic structural groupings under the control of allelic genes. Blood groups, especially for man, are identified by agglutinins supported by specific human or animal antisera and by lectins extracted from certain plants. See: blood group antigen. (25 Jun 1999) |
