| receptors, amino acid | Cell surface proteins that bind amino acids and trigger changes which influence the behaviour of cells. Glutamate receptors are the most common receptors for fast excitatory synaptic transmission in the vertebrate central nervous system, and gaba and glycine receptors are the most common receptors for fast inhibition. (12 Dec 1998) |
|---|---|
| glucogenic amino acid | <biochemistry> A type of amino acid with carbon chains that can be broken down into an intermediate of the citric acid cycle such as glycogen and then converted into glucose as a means of entering the normal process of carbohydrate metabolism in the body. Examples include: Glycine, alanine, arginine, and ornithine. (14 Oct 1997) |
| 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) |
| RNA, transfer, amino acid-specific | A group of transfer rnas which are specific for carrying each one of the 20 amino acids to the ribosome in preparation for protein synthesis. (12 Dec 1998) |
| RNA, transfer, amino acyl | Intermediates in protein biosynthesis. The compounds are formed from amino acids, ATP and transfer RNA, a reaction catalyzed by aminoacyl trna synthetase. They are key compounds in the genetic translation process. (12 Dec 1998) |
| photosystem II D1 polypeptide carboxy-terminal processing protease | <enzyme> From thylakoids; not inhibited by common protease inhibitors Registry number: EC 3.4.99.- Synonym: d1 carboxy-terminal processing protease, d1 c-terminal protease, ctpa gene product (26 Jun 1999) |
| COOH-terminal signal transamidase | <enzyme> Present in the endoplasmic reticulum; catalyses concomitant cleavage of the signal peptide of nascent proteins destined to be processed to a glycosylphosphatidylinositol (gpi) and addition of the gpi anchor Registry number: EC 2.3.2.- Synonym: cooh-ts-transamidase, gpi transamidase, gpti transamidase (26 Jun 1999) |
| polar amino acid | An alpha-amino acid in which the functional group attached to the alpha-carbon (i.e., R in RCH(NH2)COOH) has hydrophilic properties; e.g., serine, cysteine, homocysteine. (05 Mar 2000) |
| C-terminal leucine protein methyltransferase | <enzyme> Reversibly modifies protein phosphatase 2a by methyl esterification at its c-terminal leucine residues Registry number: EC 2.1.1.- Synonym: tlp methyltransferase (26 Jun 1999) |
| protein NH2-terminal asparagine deamidase | <enzyme> Converts amino terminal asparagine to aspartic acid; from porcine liver; mw about 33 kD Registry number: EC 3.5.1.- Synonym: porcine pnad (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) |
| sequence homology, amino acid | The degree of similarity between sequences of amino acids. This information is useful for the understanding of genetic relatedness of certain species. (12 Dec 1998) |
| small bowel disease involving terminal ileum | <radiology> Crohn's, TB, Yersinia (12 Dec 1998) |
