Abstract Three Sperm Activating Peptides (SAPs) have been isolated to homogeneity from the jelly coat of the eggs of a Japanese sea urchin, Anthocidaris crassispina, and two of them have been sequenced. At pH 6.8 they can stimulate the sperm respiration 20–30 fold, to the level in normal seawater (pH 8.2), and the half-maximal activation was achieved by SAPs as low as around 100 pM. The stimulative activity was both pH-and Na+-dependent. The chymotryptic fragments (res. 3–10) were 10 4–10 5 times less active, and the thermolytic fragment (res. 4–10) was 10 6 times less active than the parent SAP. CD spectra of SAPs indicate that they have unordered structure in aqueous solution.
