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.

More about this publication?
  • Protein & Peptide Letters publishes short papers in all important aspects of protein and peptide research, including structural studies, recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design etc. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallisation, and preliminary structure determinations of biologically important proteins are acceptable. Purely theoretical papers are also acceptable provided they provide new insight into the principles of protein/peptide structure and function.
