| glycine-rich beta-glycoprotein | <enzyme> A glycine-rich, heat-labile beta-glycoprotein found in blood. It is a proactivator of complement 3 in the alternate pathway of complement activation. Factor b is converted by factor d to c3 convertase. Registry number: EC 3.4.21.47 (12 Dec 1998) |

| arabinosyl-hydroxyproline transferase | <enzyme> Involved in glycoprotein synthesis in plants Registry number: EC 2.4.2.- Synonym: ar-hpt, protein-arabinosyltransferase (26 Jun 1999) |
| hydroxyproline | Specific proline residues on the amino side of a glycine residue in collagen become hydroxylated at C4, before the polypeptides become helical, by the activity of prolyl hydroxylase. This enzyme has a ferrous ion at the active site and a reducing agent such as ascorbate is necessary to maintain the iron in the ferrous state. The presence of hydroxyproline is essential to produce stable triple helical tropocollagen, hence the problems caused by ascorbate deficiency in scurvy. This unusual amino acid is also present in considerable amounts in the major glycoprotein of primary plant cell walls (see HRGP). (18 Nov 1997) |
| hydroxyproline oxidase | <enzyme> Oxidises 4-hydroxy-l-proline to delta'-pyrroline-3-hydroxy-5-carboxylate Registry number: EC 1.5.99.- (26 Jun 1999) |
| 3-hydroxyproline | A derivative of proline found in certain collagens, particularly basement membrane collagen. Synonym: 3-hydroxy-2-pyrrolidinecarboxylic acid. (05 Mar 2000) |
| 4-hydroxyproline | 4-Hydroxy-2-pyrrolidinecarboxylic acid;the trans-l-isomer is an imino acid found among the hydrolysis products of collagen; not found in proteins other than those of connective tissue. A vitamin C deficiency will result in impaired formation of hydroxyproline. (05 Mar 2000) |
| 4-hydroxyproline oxidase | A flavoenzyme that catalyses the conversion of 4-hydroxyproline to d'-pyrroline-3-hydroxy-5-carboxylate using FAD; this enzyme appears to be deficient in individuals with hyperhydroxyprolinaemia, an enzyme that catalyses the reaction of 4-hydroxyproline with NAD+ to form NADH and 4-oxoproline. Synonym: 4-oxoproline reductase. (05 Mar 2000) |
| glycine-rich beta-glycoproteinase | <enzyme> A serum protein which during the alternate pathway of complement activation converts the inactive properdin factor b to c3 convertase. Registry number: EC 3.4.21.46 (12 Dec 1998) |

| cpg-rich island | <molecular biology> Areas of DNA which consist mostly of the base pair sequence CGCGCGCG. (alternating cytosine and guanine nucleotide bases) that are usually found upstream of many genes and are thought to help regulate gene expression. They are often methylated (have methyl groups attached to the DNA segments). (28 May 1998) |
