Abstract: | The insoluble acrosome granule content of sea urchin sperm consists of a single 30,500 dalton protein named bindin. Bindin mediates species-specific recognition and adhesion of sperm to the egg surface. Bindin from (Sp) and (Sf) have tyrosine as their single N-terminal amino acid. The pI of Sp bindin is 6.62 and of Sf 6.59. Amino acid analysis reveals almost identical composition between the two species for 16 amino acids. Only two (or three) amino acids, Pro and Asx, show large species differences. Tryptic peptide maps of the two species of bindin show very similar patterns with 24 spots of identical correspondence. |
