The analysis of r.m.s. for fragments that comprise secondary structure especially a-helices and b-sheets showed that position
of b-sheet (r.m.s. 0.12–0.19 Å) are better preserved in high pressure structures than helices (r.m.s. 0.19–0.25 Å). This is in agreement with previous results for lysozyme [2] and for jelly-roll b-sandwich domain of Cowpea mosaic virus
