| 3.613 helix | The helical (commonly right-handed) form present in many proteins, deduced by Pauling and Corey from X-ray diffraction studies of proteins such as alpha-keratin; the helix is stabilised by hydrogen bonds between, e.g., ==C==O and HN== groups (symbolised by the centre dot in ==CO-HN==) of different eupeptide bonds. In a true a helix, there are 3.6 amino acid residues per turn of the helix. Synonym: 3.613 helix, Pauling-Corey helix. Collagen helix, an extended left-handed helix resulting from the high levels of glycine, l-proline, and l-hydroxyproline present in the collagens. There are 3.3 amino acids per turn of the helix. Three of those left-handed helices form a triple superhelix that is right-handed. (05 Mar 2000) |

| 3-methylglutaconicaciduria |
an aminoacidopathy characterized by excessive urinary excretion of 3-methylglutaconic acid and occurring in two forms. A mild form caused by deficiency of methylglutaconyl-CoA hydratase is characterized by speech retardation; a more severe form, of unknown etiology, is characterized by urinary excretion also of 3-methylglutaric acid and by progressive neurologic deterioration with hypotonia and optic atrophy.
