Currently, there is little information about the structure and functioning of proteins and enzymes of sea urchins. However, eggs and spermatozoa of the sea urchin Strongylocentrotus intermedius are the exceptionally convenient model for studying the patterns of development from embryo to the body as well as some other biological processes of living organisms at different stages of their development. All available published data on different enzymes and proteins of the sea urchins are discussed. The dynamics of relative change in the activity of several repair enzymes in the developing embryos during 26 stages of urchin was analyzed. It has recently been shown that living organisms contain not only very stable complexes of various proteins already described in the literature but also previously undiscovered very durable protein complexes. It has been shown that sea urchins also contain previously undescribed highly stable complexes of protein and enzymes. A comparison between very stable protein unusual complexes from sea urchin eggs, female placenta, and human milk was carried out.
