Recently scientists have contrived the alternative system to get known the structure of protein, that is x-ray analysis. In general, x-ray crystallography comprises protein crystallography as a small, but very important part. The protein is such a compound substance which has ternary structure, but it's found out just after the research of the secondary structure of protein. On the basis of x-ray crystallography the quaternary texture of protein can be described. The capability of protein texture determination depends from lots of different factors. Folding of protein is the main structural feature of protein molecule. Nowadays many scientists try to carry out the complex research of the proteins. They have already tested scientifically that all the necessary data of protein can be found in its primary structure or in protein sequence. Read the rest of this entry »
