Newly scientists have contrived the alternative system to learn the structure of protein, that is x-ray analysis. In general, x-ray crystallography includes protein crystallography as a little, but very significant part. The protein is such a complex substance that has threefold structure, but it's become known just after the study of the secondary structure of protein. Usually, on the basis of protein crystallography data it is possible do define the protein quaternary texture, but it is not always available. The ability of protein structure defining depends from many different factors. Folding of protein is the cardinal structural characteristic of protein molecule. According to all analysisses, all data about protein folding is stocked in the protein basic structure, or in protein sequence, that is why it is essential to commence any protein research from defining of sequence of protein.
