Atomic Details of Globular Protein

摘要

In the last few decades there has been considerable amount of work gone into protein structure, function and organization. Particularly there is lot of computational studies leading to understand protein structures. However the ultimate truth of real hideous information is not yet understood. In order to understand this buried information in the protein structures, the molecules were visualised on actual basis i.e. at atom level. The basic units of proteins are Carbon (C), Sulphur (S), Nitrogen (N), Oxygen (0) and Hydrogen (H). The distribution of these atoms along the protein sequences were studied. That is a question is asked; what is the probable number of C, S, N, 0 and H atoms in a given length (number of amino acids)? The results showed that given any number of lengths, the probable number of C, S, N, 0 and H atoms were 4.90, 0.05, 1.33, 1.50 and 7.77 per unit length respectively.
