| alpha-N-acylamino acid hydrolase | <enzyme> Functions in catabolism of n-acetylamino acids resulting from turnover of alpha-n-acetylated proteins Registry number: EC 3.5.1.- Synonym: alpha-n-acetylamino acid hydrolase, anaa-hase, n-acylaminoacyl-peptide hydrolase (26 Jun 1999) |
|---|---|
| bile acid 7 alpha-dehydroxylase | <enzyme> Mechanism is questionable: cholic acid - deoxycholic acid - chenodeoxycholic acid - lithocholic acid Registry number: EC 1.14.- Synonym: 7 alpha-dehydroxylase, bile acid 7-dehydroxylase, bile acid 7-alpha-dehydroxylase, bai a1, bai a2, bai a3, cholic acid 7alpha-dehydroxylase (26 Jun 1999) |
| phytanic acid alpha-oxidase | <enzyme> May be the genetic defect in refsum's disease Registry number: EC 1.14.99.- Synonym: phytanic acid alpha-hydroxylase (26 Jun 1999) |
| amino- | <prefix> Prefix denoting a compound containing the radical, -NH2. Origin: an(monia) + in(e) + -o- (05 Mar 2000) |
| 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 acids, peptides, and proteins | Amino acids and chains of amino acids connected by peptide linkages. (12 Dec 1998) |
| amino acyl-tRNA ligases | <enzyme> Any of the group of ligases that catalyses the ATP-driven formation of a bond between an amino acid and a trna, activating the amino acids as a step in protein synthesis. Individual enzymes are highly specific for one amino acid and for any trna corresponding to that amino acid. Registry number: EC 6.1.1. (12 Dec 1998) |
| amino alcohols | Compounds possessing both a hydroxyl (-oh) and an amino group (-nh2). (12 Dec 1998) |
| amino group | <biochemistry> An -NH2 group. Organic compounds which have this group are called amines. (09 Oct 1997) |
| amino sugar | <biochemistry> Monosaccharide in which an OH group is replaced with an amino group, often acetylated. Common examples are D galactosamine, D glucosamine, neuraminic acid, muramic acid. Amino sugars are important constituents of bacterial cell walls, some antibiotics, blood group substances, milk oligosaccharides and chitin. (18 Nov 1997) |
| amino sugars | Sugar's in which a hydroxyl group has been replaced with an amino group; e.g., d-glucosamine. (05 Mar 2000) |
| 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) |
