P Structure of proteins

The first protein structure to be learned was that of myoglobin, which was established by Kendrew et al. in I960.391-393 That of the enzyme lysozyme was deduced by Blake et al. in 1965.394 Since then, new structures have appeared at an accelerating rate so that today we know the detailed architecture of over 6000 different proteins395 with about 300 distinctly different folding patterns 396 New structures are being determined at the rate of about one per day. X-ray diffraction has also been very important to the study of naturally or artifically oriented fibrous proteins397 and provided the first experimental indications of the P structure of proteins.
