[Theoretical conformational analysis of a encephalitogenic peptide molecule and a study of the structure-activity relationship in a series of its analogs].
Semi-empirical energy calculations are used to determine all low-energy conformations of Trp-containing fragment 113-121 of myelin basic protein (experimental allergic encephalomyelitis inducing peptide). The computed conformations are compared with the results of physico-chemical experiments and data on biological testing of the encephalitogenic peptide analogs. The three computed structures are shown to be in a good agreement with the available experimental evidence. However, additional information is required to predict "biologically active" conformation of encephalitogenic peptide.
