Fourteen peptides were isolated from the egg jelly of sea urchins, Pseudocentrotus depressus, Strongylocentrotus purpuratus, Hemicentrotus pulcherrimus and Anthocidaris crassispina and their amino acid sequences were determined. 2. The peptides stimulated H. pulcherrimus sperm respiration one half-maximally at about 8-60 pM. 3. Addition of speract to intact spermatozoa of P. depressus, H. pulcherrimus and A. crassispina resulted in the appearance of a newly stained protein (Mr 128,000 for P. depressus, Mr 128,000 for H. pulcherrimus and Mr 131,000 for A. crassispina) on sodium dodecyl sulfate-polyacrylamide gels.
