Phylogenetic tree of ArcA. The protein sequences of the two ArcA protein sequences from M. pneumoniae (MPN304 and MPN560), ArcA sequences from other Mycoplasma species, and the protein sequence of arginine deiminase from Streptococcus pneumoniae strain R6 (spr0822_Spn_R6) were aligned and a tree was generated from the alignment. Confidence values, represented as percent of supporting bootstrapping iterations are shown for each node. Scale, in differences per site, is indicated at the bottom
