MOESM4 of Identification of a new alanine racemase in Salmonella Enteritidis and its contribution to pathogenesis

Additional file 4: Figure S3. (A) Sequence alignment of three alanine racemases from S. Enteritidis (Alr, DadX, SEN3897). Alr (SEN4016) showed 91% with Y274f Alanine Racemase from E. Coli (PDB-ID-4WR3), DadX (SEN1235) showed 48% identity with Alanine Racemase from Pseudomonas aeruginosa, (PDB-ID-1RCQ) and SEN3897 showed 42% identity with Chain A, Alanine Racemase from Bartonella henselae (PDB-ID-3KW3). (B) Ribbon protein structures determined by I-TASSER. Superimposed alanine racemase structures of Alr (green), DadX (red) and SEN3897 (turquoise Blue) denote their structural similarities with residue conservation.
