Comparison of 3D structures with TOPOFIT of PstS from B. subtilis (red), with (a) B. sp. NRRL-14911 (cyan; r.m.s.d. = 1.02, z-score = 39.89), (b) Bacillus sp. m3-13 (green; r.m.s.d. = 1.53, z-score = 20.24) and (c) B. coahuilensis m4-4 (yellow; r.m.s.d. = 1.49, z-score = 9.65). Residues involved in phosphate binding are highlighted in purple. (d) shows an alignment of the active site of PstS and the different amino acids involved in phosphate binding are highlighted in gray.
