There are a lot of methods to research the structure of protein, but the most precise is x-ray analysis. Protein crystallography is considered to be just a part of x-ray crystallography but it is really significant. The protein is such a complicated substance which has threefold structure, but it's found out only after the research of the secondary structure of protein. Sometimes, on the basis of protein crystallography information it is possible do define the protein quaternary structure, but it is not always available. The capability of protein structure determination depends from many various factors. The main properties of protein is the protein folding. According to all theories, all data about protein folding is stocked in the protein basic structure, or in protein sequence, that is why it is essential to start any protein research from determination of sequence of protein.
