Abstract: Site-directed mutagenesis was used to examine the roles of the conserved histidine, arginine and cysteine residues in acid phosphatase from Prevotella intermedia (PiACP). The replacement of histidine and arginine residues resulted in the elimination of the PiACP activity while the cysteine mutants retained activity. These results suggest that the histidine and arginine residues are essential for catalysis.
