| amino-terminal | <biochemistry> The end of a protein or polypeptide chain with the unattached amino group or the aminoacyl residue containing it. Each amino acid in the chain has an amino group on one side, which is attached to the carboxyl group (COOH 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 carboxyl terminal. Synonym: NH2-terminal. (14 Aug 2000) |

| 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) |
| 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) |
| 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) |
| N-(5'-phosphoribosylformimino)-5-amino-1-(5''-phosphoribosyl)-4-imidazolecarboxamide isomerase | <enzyme> Has beta/alpha-barrel fold structure; involved in biosynthesis of histidine Registry number: EC 5.3.1.16 Synonym: hisa gene product, pfacr isomerase, phosphoribosylformimino-5-aminoimidazole carboxamide ribotide isomerase (26 Jun 1999) |
| succinylalanyl-alanyl-prolyl-phenylalanyl-7-amino-4-methylcoumarin hydrolase | <enzyme> Enzyme may be involved in attainment of transformed state Registry number: EC 3.4.24.- Synonym: suc-ala-ala-pro-phe-amc hydrolase, saapp-amc-hydrolase (26 Jun 1999) |
| essential amino acids | Alpha-amino acids nutritionally required by an organism and which must be supplied in its diet (i.e., cannot be synthesised by the organism) either as free amino acid or in proteins. (05 Mar 2000) |
| excitatory amino acids | Endogenous amino acids released by neurons as excitatory neurotransmitters. Glutamic acid is the most common excitatory neurotransmitter in the brain. Aspartic acid has been regarded as an excitatory transmitter for many years, but the extent of its role as a transmitter is unclear. (12 Dec 1998) |
| 2-amino-2-deoxy-D-galactose | <chemical> Chemical name: D-Galactose, 2-amino-2-deoxy- (12 Dec 1998) |
| 2-amino-5-phosphonovalerate | <chemical> A potent and specific antagonist of nmda receptors (receptors, nmda) in the d-enantiomeric form. The l form is inactive at nmda receptors but may affect the ap4 (2-amino-4-phosphonobutyrate; apb) excitatory amino acid receptors. Pharmacological action: excitatory amino acid antagonists. Chemical name: Norvaline, 5-phosphono- (12 Dec 1998) |
| (3-(arginyl)amino-4-(4-nitrophenyl)butyryl)-leucyl-prolyl-threonine | Pharmacological action: neurotransmitters Synonym: 2-afb(p-no2)-proctolin, (afb(p-no2)(2))-proctolin (26 Jun 1999) |
| 8-amino-7-oxononanoate synthase | <enzyme> Chemical name: 7-keto-8-aminopelargonic acid synthetase Registry number: EC 2.3.1.47 Synonym: 7-kap synthetase, 8-amino-7-oxopelargonate synthase, 7-oxo-8-aminononanoate synthase, biof gene product (26 Jun 1999) |
| Rambourg's chromic acid-phosphotungstic acid stain | <technique> A stain for glycoproteins, used with an electron microscope, with which ultrathin tissue sections reveal complex carbohydrates in the same locations as shown by Rambourg's periodic acid-chromic methenamine-silver stain. (05 Mar 2000) |
| a1-acid glycoprotein | <biology> Plasma protein of mammals and birds, 38% carbohydrate. In humans a single chain glycoprotein of 39 kD. Increased levels are associated with inflammation, pregnancy and various diseases. (18 Nov 1997) |
| abscisic acid | <biochemistry> A lipid hormone that inhibits cell growth in plants, it is associated with fruit drop, leaf death and seed dormancy. It is synthesised in the plastids from carotenoids. This hormone helps plants deal with water loss, and its effects can be reversed with gibberellins. (06 May 1997) |
