Figure 1. RoxP is highly conserved.

Figure 1

The protein sequences of RoxP homologs were extracted from all available P. acnes genomes. The tree, generated by the minimum-evolution algorithm in MEGA version 5.2, illustrates that RoxP is highly conserved among the vast majority of P. acnes strains. Most strains (58) have an identical homolog, and 33 strains have highly similar homologs (99% identity). A subgroup of 11 RoxP homologs belonging to strains of P. acnes type II, type III, and P. humerusii are more distant (83% identity). Some genomes, such as JCM strains, encode a truncated RoxP. The bar represents the genetic distance.
