title: Raman spectroscopic study on the conformation of 11 S form acetylcholinesterase from Torpedo californica.
abstract: Vibrational Raman spectroscopy has been used to study the conformation of the 11 S form of acetylcholinesterase from Torpedo californica. Secondary structure analysis by the method of Williams [(1983) J. Mol. Biol. 166, 581-603] shows 49% alpha-helical structure, 23% beta-sheets, 11% turns and 15% undefined structure. Secondary structure estimates obtained for this enzyme by Raman spectroscopy and circular dichroism have been analyzed.
