Abstract

The schistosome eggshell is composed of two kinds of cross-linked proteins. One is glycine rich and the other is extremely tyrosine rich and highly repetitive. The highly conserved sequence of the tyrosine residues in the tyrosine rich protein suggests that it may play a role as an electron transport chain during eggshell cross-linking. Studies using model synthetic peptides suggest that the tyrosine rich protein may adopt a left-handed structure, possibly a left-handed alpha-helix.
