A main technique for protein structure detection is x-ray dissection, which is named x-ray crystallography. Actually, the protein crystallography is not detached part, but it is very essential part of x-ray crystallography. Protein crystallography does permit defining protein secondary structure and afterward threefold structure of protein. Usually, on the basis of protein crystallography information it is possible do determine the protein quaternary structure, but it is not always available. The capability of protein texture defining depends from many different factors. Folding of protein is the main structural feature of protein molecule. In compliance with all analysisses, all information about protein folding is collected in the protein basic structure, or in protein sequence, that is why it is important to begin any protein analysis from determination of sequence of protein.
