title: [Dynamics of evolutionary rates of proteins from small ribosomal subunits].
abstract: Phylogenetic analysis of small ribosomal subunit proteins was performed. Plausible taxon-specific acceleration of evolutionary rates ("leading") of base substitution of some ribosomal proteins and 16S rRNA sites in different phyletic lines were revealed. The limited number of synchronously changing proteins is discussed in terms of relay-race model of coevolution of ribosome. The analogy with dilemma of Haldane is drawn. Plausible differences in the evolutionary rates of regions with different secondary structure were revealed. Changes in correlation of evolutionary rates of regions with different secondary structure during leading were determined. It is anticipated that S14 with S19 ribosomal proteins and S7 with corresponding site on 16S rRNA change co-evolutionary.
