Additional file 9: of Antagonism between Staphylococcus epidermidis and Propionibacterium acnes and its genomic basis

A. Amino acid sequences of the PSMβ-proteins from S. epidermidis 14.1.R1. The sequence shown in bold red represents the sequence coverage by MS analysis. The sequence coverage was 70 % and 40 % for PSMβ2 and PSMβ1a/1b, respectively. B. The psmβ operon is composed of four genes in the S. epidermidis strain 14.1.R1. The two peptides PSMβ1a (HMPREF9956_0861), and PSMβ1b (HMPREF9956_0860) are identical on protein level; on DNA level there are 3 single nucleotide polymorphisms. (DOCX 26 kb)
