Gene Organization and Deduced Amino Acid Sequence for Pherophorin-DZ1.

(A) Restriction map and intron/exon organization of the dz1 gene cloned from a genomic library. Black bars represent exons, and the gray bar indicates a GC-rich stretch encoding a polyproline sequence.

(B) Deduced amino acid sequence of pherophorin-DZ1. The characteristic polyproline stretch is shown on a gray background. Amino acid sequences confirmed from isolated peptides are underlined. The arrowhead marks the potential signal peptidase cleavage site. The broken line marks the C-terminal part of the polypeptide found to be homologous with the sex-inducing pheromone.
