Sequence alignments of R1a/R2a and R2a/R2b with repeat sequences of different staphylococcal amidases. The alignments were calculated with the programs ClustalW2 (46), MUSCLE (10), and MAFFT (20) and combined into a single output using COMBINE (31). Conserved amino acids are color coded according to their degree of conservation as follows: gray, <80%; pink, 80 to 90%; red, 100%. Linker regions at the N termini of repeats R1a and R2a are omitted in the alignment and shown separately in Fig. 7D.
