摘要: Abstract The D group proteins are major secretory products of the tubular accessory glands male mealworm beetles ( Tenebrio molitor ). They vary in apparent molecular mass between 22 and 30 kDa. In this paper we present deduced amino acid sequence two similar acidic proteins, termed D1 D2. These have a structure based on peculiarly repeated sequences. Both molecules consist three domains. Proceeding from terminus, A A′ domains predicted to contain long alpha helical segments. carboxy-terminal region or B domain is basic composed shorter stretches interrupted by turns. D2 differ number repeats within
