title: [Analysis of interactions of buried polar side chains in beta-proteins].
abstract: It was shown in qualitative and quantitative analyses of polar side chains inaccessible for water molecules as well as their interactions in 100 globular beta-structural proteins that completely buried polar side chains are widespread in beta-proteins, their vast majority being involved in "side chain-side chain" or "side chain-main chain" interactions. The analysis of the occurrence of different "side chain-partner" pairs permitted us to demonstrate that such interactions are selective. The results were compared with similar data obtained previously for alpha-helical proteins.
