title: [The effect of amino acid substitutions on the 3-dimensional structure of fragment 1--16 of the oncoprotein p21 ras].
abstract: Using the method of theoretical conformational analysis, spatial structure of fragment 1-16 of active [( Val12-Gly13], [Asp12-Gly13], [Gly12-Asp13]) and passive [( Gly12-Gly13] and [Pro12-Gly13]) modifications of oncoproteins family p21 ras have been investigated. The activation of these proteins has been shown to be accompanied by reorganization of three-dimensional structure of the polypeptide chain.
