Summary
The main features of the B family of chorion proteins in saturniid moths were examined by partial sequencing of representative B proteins, seven fromAntheraea polyphemus and two fromA. pernyi. Comparisons were made to sequences derived from seven recombinant DNA clones representing three types of B family proteins ofA. polyphemus. The central regions of the sequences are conservative, both within and between moth species, and differ largely by a few amino acid replacements, rather than deletions or insertions. By contrast, the amino-terminal third varies more substantially, in a manner which defines two protein subfamilies: within each subfamily sequences are similar, but the subfamilies differ by at least two multiresidue deletions as well as by amino acid replacements. These properties are analogous to features of the A family of chorion proteins.
