| amino-terminal residue | <biochemistry> The only amino acid residue in a polypeptide chain that has a free alpha-amino group, it defines the amino terminus of the polypeptide. (09 Oct 1997) |
|---|---|
| axonal terminal boutons | The somewhat enlarged, often club-shaped endings by which axons make synaptic contacts with other nerve cells or with effector cells (muscle or gland cells). As isolated, by homogenizing brain or spinal cord, they contain acetylcholine and the related enzymes. Terminals contain neurotransmitters of various kinds, sometimes more than one. These can be demonstrated by chemical analysis and immunocytochemical methods. See: synapse. Synonym: axonal terminal boutons, end-feet, neuropodia, pieds terminaux, synaptic boutons, synaptic endings, synaptic terminals, terminal boutons, bouton terminaux. (05 Mar 2000) |
| carboxyl terminal | The end of a polypeptide chain with the unattached carboxyl group (a -COOH group). Each amino acid in the middle of the chain has an amino group (a -NH2 group) on one side (which is attached to the carboxyl group of the previous amino acid) and a carboxyl group on the other side (which is attached to the amino group of the next amino acid). The other end of the polypeptide chain is called the amino terminal. (09 Oct 1997) |
| carboxyl-terminal residue | This amino acid residue defines the carboxylterminus of the polypeptide, its the only residue with a free alpha-carboxyl group. (09 Oct 1997) |
| carboxy terminal | The end of a peptide or protein having a free carboxyl (-COOH) group. (05 Mar 2000) |
| carboxy-terminal domain kinase | <enzyme> Protein kinase that phosphorylates the c-terminal repeat domain of the largest subunit of RNA polymerase II at serine residues Registry number: EC 2.7.1.- Synonym: ctd kinase, hs-ctd kinase, tfiih-associated ctd kinase (26 Jun 1999) |
| central terminal electrode | In electrocardiography, an electrode in which connections from the three limbs (right arm, left arm, and left leg) are joined and led to the electrocardiograph to form the indifferent electrode, theoretically at zero potential for the system. (05 Mar 2000) |
| RNA 3'-terminal phosphate cyclase | <enzyme> ATP dependent; forms 2',3' terminal cyclic phosphate on RNA which is then the substrate for RNA ligase of hela cells Registry number: EC 6.5.- Synonym: RNA tph cyclase (26 Jun 1999) |
| c-Jun amino-terminal kinase | <enzyme> A stress-activated protein kinase; 46-kD kinase that phosphorylates ser(63) and ser(73) of c-jun; similar to yeast hog1 kinase; amino acid sequence given in second source; genbank l23118 Registry number: EC 2.7.10.- Synonym: jn kinase, jnk1 protein kinase, jnk-46, jnk1 protein, jun-nh2-terminal kinase, stress-activated protein kinase 1, sap kinase-1, sapk1, p46 sap kinase, c-jun kinase-1 (26 Jun 1999) |

| protein N-terminal acetyltransferase | <enzyme> From saccharmyces cerevisiae; encodes a catalytic subunit of an n-terminal acetyltransferase; ard1 and nat1 proteins are subunits of this enzyme Registry number: EC 2.3.1.- Synonym: nat1 gene protein, saccharomyces, yeast protein n-terminal acetyltransferase, n-terminal protein acetyltransferase, ard1 protein (26 Jun 1999) |
| HIV long-terminal repeat | Regulatory sequences important for viral replication that are located on each end of the HIV genome. The ltr includes the HIV enhancer, promoter, and other sequences. Specific regions in the ltr include the negative regulatory element (nre), nf-kappa b binding sites , sp1 binding sites, tata box, and trans-acting responsive element (tar). The binding of both cellular and viral proteins to these regions regulates HIV transcription. (12 Dec 1998) |
