Hexapeptide repeat structure in Dictyostelium spore coat protein.
The sequences of the NH2-termini of two spore coat proteins of Dictyostelium discoideum have been determined. One of them (SP60) consists of perfect hexapeptide repeats of the sequence Gly-Asp-Trp-Asn-Asn-Asx-. The sequence has some homology to the parvovirus capsid protein which does not display periodicity. The NH2-terminal sequence of the second protein, SP70, contains a modified amino acid in two positions and like SP60 is highly hydrophilic and acidic.
