| peptide chain elongation | The process whereby an amino acid is joined through a substituted amide linkage to a chain of peptides. (12 Dec 1998) |
| peptide elongation factor tu | A protein found in bacteria and eukaryotic cells which delivers aminoacyl-trna's to the a site of the ribosome. The aminoacyl-trna is first bound to a complex of elongation factor tu containing a molecule of bound GTP. The resulting complex is then bound to the 70s initiation complex. Simultaneously the GTP is hydrolyzed and a tu-GDP complex is released from the 70s ribosome. The tu-GTP complex is regenerated from the tu-GDP complex by the ts elongation factor and GTP.

| sign of elongation | <microscopy> Referring to the elongation of a substance in relation to refractive indices. If it is elongated in the direction of the high refractive index, it is said to have a positive sign of elongation. If it is elongated in the direction of the low refractive index, it has a negative sign of elongation, not to be confused with the sign of double refraction (i.e., optic sign). (05 Aug 1998) |
| elongation | <radiobiology> Parameter indicating the degree to which the cross-section of a toroidal plasma is non-circular. Kappa=b/a, where b and a are the vertical and horizontal minor radii. As kappa is increased, the confinement in relation to the total current improves, but the plasma also becomes more and more unstable to vertical displacements. A circular plasma has kappa of 1, a common value for elongated plasmas is 1.7, and the absolute limit is probably around 2. (09 Oct 1997) |
| elongation factor | <biochemistry> Peptidyltransferase components of ribosomes that catalyse formation of the acyl bond between the incoming amino acid residue and the peptide chain. There are three classes of elongation factor: EF1_ (EF Tu in prokaryotes) binds GTP and aminoacyl tRNA, delivering it to the A site of ribosomes. EF 1_ (EF Ts) helps in regeneration of GTP EF 1_. EF 2 (EF G) binds GTP and peptidyl tRNA and translocates it from the A site to the P site. Diptheria toxin inhibits protein synthesis in eukaryotes by adding an ADP ribosyl group to a modified histidine residue (dipthamide) in elongation factor II. (18 Nov 1997) |
| GTP | An immediate precursor of guanine nucleotides in RNA; similar to ATP; has a crucial role in microtubule formation. GTP cyclohydrolase, an enzyme that catalyses the reaction of GTP and H2O forming formate and a precursor of tetrahydrobiopterin; a deficiency of this enzyme will result in one form of malignant hyperphenylalaninaemia. Acronym: GTP (05 Mar 2000) |
| GTP-binding protein | <molecular biology, protein> There are two main classes of G-proteins, the heterotrimeric G proteins that associate with receptors of the seven transmembrane domain superfamily and are involved in signal transduction and the small cytoplasmic G-proteins. Regulatory proteins found in all cells. They are versatile molecular switches, involved in the control of a wide range of biological processes - protein synthesis, signal transduction pathways, growth and differentiation. They all act through a common molecular mechanism based on their ability to bind the guanine nucleotides GTP and GDP selectively and with high affinity. Stimulatory G-proteins are permanently activated by cholera toxin, inhibitory ones by pertussis toxin. Transducin was one of the first of the heterotrimeric G-proteins to be identified. The small G-proteins are a diverse group of monomeric GTPases that include ras, rab, rac and rho and that play an important part in regulating many intracellular processes including cytoskeletal organisation and secretion. Their GTPase activity is regulated by activators (GAPs) and inhibitors (GIPs) that determine the duration of the active state. (12 Jul 2000) |
| GTP cyclohydrolase | <enzyme> (GTP cyclohydrolase I) or GTP 7,8-8,9-dihydrolase (pyrophosphate-forming) (GTP cyclohydrolase II). An enzyme group that hydrolyzes the imidazole ring of GTP, releasing carbon-8 as formate. Two c-n bonds are hydrolyzed and the pentase unit is isomerised. This is the first step in the synthesis of folic acid from GTP.6 (GTP cyclohydrolase I) and GTP cyclohydrolase II. Chemical name: GTP 7,8-8,9-dihydrolase Registry number: EC 3.5.4.16 (12 Dec 1998) |
| GTP phosphohydrolase | <enzyme> An enzyme that hydrolyzes GTP to GDP and provides energy for peptide chain elongation. Registry number: EC 3.6.1.- (12 Dec 1998) |
| GTP pyrophosphokinase | <enzyme> An enzyme that catalyses reversibly the transfer of a pyrophosphate group from ATP to the 3'-oh group of GDP or GTP with the formation of guanosine 3'-diphosphate 5'-diphosphate or guanosine 3'-diphosphate 5'-triphosphate and AMP. The enzyme, also called stringent factor, is located in the rela gene in stringent strains of bacteria. The above synthesis is induced by mRNA and uncharged trna which is bound to the aminoacyl-t-RNA binding site of the ribosome by a codon-specific association. Chemical name: ATP:GTP 3'-pyrophosphotransferase Registry number: EC 2.7.6.5 (12 Dec 1998) |

| phosphoenolpyruvate carboxykinase (GTP) | <enzyme> An enzyme of the lyase class that catalyses the conversion of GTP and oxaloacetate to GDP, phosphoenolpyruvate, and carbon dioxide. This reaction is part of gluconeogenesis in the liver. The enzyme occurs in both the mitochondria and cytosol of mammalian liver. Chemical name: GTP:oxaloacetate carboxy-lyase (transphosphorylating) Registry number: EC 4.1.1.32 (12 Dec 1998) |
| transducin GTP phosphohydrolase | <enzyme> Stimulated by bovine rhodopsin mutants (asp63 to asn) and (glu134 to gln) with slightly lowered efficiency Registry number: EC 3.6.1.- Synonym: transducin GTPase (26 Jun 1999) |
| age factors | Age as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or the effect of a circumstance. It is used with human or animal concepts but should be differentiated from aging, a physiological process, and time factors which refers only to the passage of time. (12 Dec 1998) |
