... that, by and large, the modular evolution of pro- teins is dominated by two major types of events: fusion, on the one hand, and deletion and fission on the other [3,4,21,28]. Exon shuffling and recombination seem ... modular evolution of proteins are gene duplication, fusion and fission, recombination and loss of frag- ments. While a large body of research has focused on duplic...

At increasing VtA 3 concentrations ... as H 2 O 2 production and Ca 2+ liberation. This mem- branotropic effect may explain the high toxicity of viscotoxins in particular and thionins in general. In conclusion, our results st...
