  1. The putative proteinase cleavage sites (P1/P1') of inhibitory serpins rarely change between the D. melanogaster and D. grimshawi orthologues and the RCL sequence is more strongly conserved than the serpin core. The RCL of non-inhibitory serpin-folds tends to be weakly conserved, with three exceptions, Spn31A, Spn43Ab and Spn85F. The putative RCL of the serpin-related fold, Spn100A, is conserved slightly more strongly than the remainder of the protein.
