Predicted protein–protein interactions of CaCAs according to their orthologs in S. bicolor. In the network, only the pairs with more than 60 % sequence identity between SbCaCAs, ShCaCAs, or SsCaCAs and SbCaCAs and with an interaction score > 0.4 are shown. Line and node colors indicate the different types and degrees of interactions, respectively. The filled or empty nodes represent known or unknown 3D structures, respectively. The gene names in parentheses indicate that paralogous or orthologous gene names
