| amino acid chloromethyl ketones | <chemical> Inhibitors of serine proteinases and sulfhydryl group-containing enzymes. They act as alkylating agents and are known to interfere in the translation process. Pharmacological action: alkylating agents, protein synthesis inhibitor, serine proteinase inhibitors. (12 Dec 1998) |
|---|---|
| amino acid dehydrogenases | Enzymes catalyzing the oxidative deamination of amino acids to the corresponding oxo (keto) acids; two relatively non-specific varieties exist, l and d, for which l-amino acids and d-amino acids are the respective substrates; the products include NH3 and a reduced hydrogen acceptor (NADH in the l case); amino acid dehydrogenases of greater specificity exist, (e.g., glycine dehydrogenase). Compare: amino acid oxidases. (05 Mar 2000) |
| amino acid isomerases | <enzyme> Enzymes that catalyze either the racemization or epimerization of chiral centres within amino acids or derivatives. Registry number: EC 5.1.1.- (12 Dec 1998) |
| amino acid naphthylamidases | <enzyme> Registry number: EC 3.4.11. (12 Dec 1998) |
| amino acid neurotransmitters | Amino acids released by neurons as intercellular messengers. Among the amino acid neurotransmitters are glutamate (glutamic acid) and gaba which are, respectively, the most common excitatory and inhibitory neurotransmitters in the central nervous system. (12 Dec 1998) |
| amino acid oxidases | Flavoenzymes oxidizing, with O2 and H20, either l-or d-amino acids specifically, to the corresponding 2-keto acids, NH3 and H2O2. Compare: amino acid dehydrogenases, yellow enzyme. (05 Mar 2000) |
| amino acid oxidoreductases | <enzyme> A class of enzymes that catalyze oxidation-reduction reactions of amino acids. Registry number: EC 1.4. (12 Dec 1998) |
| amino acid permease | <enzyme> A widely distributed group of large Integral membrane proteins, required for the entry of amino acids into cells. (18 Nov 1997) |
| amino acid reagent | A reagent used in the identification and quantification of amino acids. (05 Mar 2000) |
| amino acid receptor | <biochemistry> Ligand gated ion channels with specific receptors for amino acid transmitters. An extended protein superfamily that also includes subunits of the nicotinic acetylcholine receptor. (18 Nov 1997) |
| amino acids | Organic compounds that generally contain an amino (-nh2) and a carboxyl (-cooh) group. Twenty alpha-amino acids are the subunits which are polymerised to form proteins. (12 Dec 1998) |
| amino acids, branched-chain | Amino acids which have a branched carbon chain. (12 Dec 1998) |
| amino acids, cyclic | A class of amino acids characterised by a closed ring structure. (12 Dec 1998) |
| amino acid sequence | The sequence of amino acids as arrayed in chains, sheets, etc., within the protein molecule. This is referred to as the primary structure of proteins. It is of fundamental importance in determining protein conformation. (12 Dec 1998) |
| amino acids, peptides, and proteins | Amino acids and chains of amino acids connected by peptide linkages. (12 Dec 1998) |
