Title: The regularity of changes of the Chou-Fasman parameters within the genetic code. Author: Siemion IZ. Journal: Biosystems; 1994; 32(1):25-35. PubMed ID: 7517193. Abstract: It has been shown that Chou-Fasman conformational parameters of amino acids, which reflect their ability to adopt a definite conformation within the peptide chain, change very regularly within the genetic code, arranged in the manner discussed recently by Siemion and Stefanowicz (1992a) (BioSystems 27, 77-84). Two mutually perpendicular C2 axes of pseudosymmetry appear in the center of the diagrams (between ACY and ACR threonine codons) presenting the changes of P alpha and P beta parameters. The left and right parts of diagrams superimpose on each other quite well when the symmetry operation involving a proper axis is performed. This phenomenon is due, in our opinion, to the regular arrangement of equivalent codons in the 'one-step mutation' ring formed by 64 triplets of the genetic code.[Abstract] [Full Text] [Related] [New Search]
