Two disulphide bridges are present in juvenile hormone binding protein from Galleria mellonella.

Abstract

The hemolymph juvenile hormone binding protein (JHBP) from Galleria mellonella contains two disulphide bridges/molecule and no free Cys residues. An alignment of primary structures of other Lepidopteran JHBPs indicates that Cys residues, equivalent to Cys10,17,151,195 in G. mellonella JHBP, maybe involved in -S-S- bridge formation.
