Fig 4. Bayesian tree based on the [Extracellular] dataset.

Peptides were obtained from extracellular proteins. Bayesian analysis was performed in two independent runs using four Markov chains and 1,000,000 generations [58]. A majority-rule consensus tree (50%) was obtained after discarding the initial 25% of the trees and only support above 60% is shown. The leaf labels refer to the current NCBI nomenclature, whereas the BCG groups represent the recently revised names [12].
