| carbohydrate conformation | The characteristic 3-dimensional shape of a carbohydrate. (12 Dec 1998) |
| molecular conformation | The characteristic three-dimensional shape of a molecule. (12 Dec 1998) |
| conformation | The three-dimensional arrangement of side groups on a molecule which canfreely rotate into different positions without breaking any bonds. (09 Oct 1997) |
| protein conformation | The characteristic 3-dimensional shape of a protein, imposed upon it by the secondary and tertiary structure of the peptide chain. This stage in the structure of a protein describes the highest level of organization in overall structure assumed by multimeric proteins (aggregates of more than one polypeptide chain). This is the fourth folding level of protein building. (12 Dec 1998) |
| native conformation | <chemistry> The conformation in which a molecule is biologically active. (09 Oct 1997) |
| nucleic acid conformation | The characteristic 3-dimensional shape of a nucleic acid or polynucleotide. Its secondary structure is due to the formation of hydrogen bonds between nucleotides, resulting in base pairing and areas with alpha helix structure. (12 Dec 1998) |
| envelope conformation | See: Haworth conformational formulas of cyclic sugars. (05 Mar 2000) |
| alpha-dextrin endo-1,6-alpha-glucosidase | <enzyme> An enzyme with action similar to that of isoamylase; it cleaves 1,6-alpha-glucosidic linkages in pullalan, amylopectin, and glycogen, and in alpha-and beta-amylase limit-dextrins of amylopectin and glycogen. Compare: isoamylase. Synonym: limit dextrinase, pullulanase, R enzyme. (05 Mar 2000) |
| mannosyl-glycoprotein endo-beta-n-acetylglucosaminidase | <enzyme> A group of related enzymes responsible for the endohydrolysis of the di-n-acetylchitobiosyl unit in high-mannose-content glycopeptides and glycoproteins. Chemical name: Glycopeptide-D-mannosyl-N(4)-(N-acetyl-D-glucosaminyl)2-asparagine 1,4-N-acetyl-beta-glucosaminohydrolase Registry number: EC 3.2.1.96 (12 Dec 1998) |
| glucan endo-1,3-beta-d-glucosidase | <enzyme> An enzyme that hydrolyzes 1,3-beta-d-glucosidic linkages in 1,3-beta-d-glucans including laminarin, paramylon, and pachyman. Chemical name: 1,3-beta-D-Glucan glucanohydrolase Registry number: EC 3.2.1.39 (12 Dec 1998) |
| glycoprotein endo-alpha-1,3-mannosidase | <enzyme> An endomannosidase; cleaves glucosyl alpha1-3-mannose from monoglucosylated oligosaccharide (glcman(7-9)glcnac) of the glycoprotein produced in the golgi membrane Registry number: EC 3.2.1.130 Synonym: glucosyl mannosidase (26 Jun 1999) |
| xyloglucan endo(1-4)-beta-D-glucanase | <enzyme> Hydrolyzes only xyloglucans Registry number: EC 3.2.1.- Synonym: xyloglucanase (26 Jun 1999) |
| endo- | <prefix> Prefixes indicating within, inner, absorbing, or containing. See: ento-. Origin: G. Endon, within (05 Mar 2000) |
