  1. aDistance values are presented as mean ± standard error computed by bootstrapping of 1,000 replicates. Bold-face and regular letters indicate intra-group and inter-group rates, respectively.
  2. bThe proteins were categorized into groups by considering primary structures and taxonomical positions of donor organisms.
