| FMD | <disease> A highly infectious disease of wide distribution and great economic importance, occurring in cattle, swine, sheep, goats and all wild and domestic cloven-footed animals caused by a picornavirus (genus Rhinovirus) and characterised by vesicular eruptions in the mouth, tongue, hoofs, and udder; humans are rarely affected. Synonym: aftosa. (05 Mar 2000) |
| FMD virus | A picornavirus of the genus Rhinovirus causing foot-and-mouth disease of cattle, swine, sheep, goats, and wild ruminants; it has wide distribution throughout Africa and Asia, causing serious economic losses; the virus is spread by contamination of the animal environment with infected saliva and excreta. Synonym: FMD virus. (05 Mar 2000) |
| fMet | Methionine acylated on the NH2 group by a formyl (-CHO) group. This is the starting amino acid residue for virtually all bacterial polypeptides. See: initiating codon. Synonym: N-formylmethionine. (05 Mar 2000) |
| fMet-tRNA | <abbreviation> Formylmethionyl tRNA. (05 Mar 2000) |
| FMF | An inherited intestinal disorder that is characterised by recurrent fevers and intestinal inflammation. Usually has onset between the ages of 5 and 15 years and is more common in those of Mediterranean descent. Symptoms include fevers and abdominal pain. Some may also suffer from chest pains, multiple joint pains and red swollen legs. (27 Sep 1997) |
| fMLP | <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) |
| fmn | <chemical> Riboflavin 5'-(dihydrogen phosphate). A coenzyme for a number of oxidative enzymes including NADH dehydrogenase. It is the principal form in which riboflavin is found in cells and tissues. Chemical name: Riboflavin 5'-(dihydrogen phosphate) (12 Dec 1998) |
| FMO3 | Abbreviation for the enzyme, flavin-containing monooxygenase-3. See Fish-odour syndrome. (12 Dec 1998) |
| FMR1 | The gene responsible for the production of a protein called FMRP. Lack of FMRP results in the fragile X syndrome. (FMRP is an acronym composed of the first letters of Familial Mental Retardation Protein). (12 Dec 1998) |
| FMRFamide | <protein> Phe Met Arg Phe NH2, a tetrapeptide neurotransmitter, a member of the same family of RFamide peptides as FLRFamide, sharing the same C terminal RFamide sequence. (18 Nov 1997) |
| FMRP | As stated in the entry for FMR1, FMRP is an acronym composed of the first letters of Familial Mental Retardation Protein. (12 Dec 1998) |
| fms | <oncogene> An oncogene, identified in a feline sarcoma, encoding a tyrosine protein kinase, as part of a mutant receptor for macrophage colony-stimulating factor. (18 Nov 1997) |
