pKa Calculations

A. pKa calculation (Theory)

B. Performing pKa calculation (Practice)

Aftre login to your account in, follow this pKa Calculation Procedure.

Summary for the procedures:
  • 1) Copy the 6 basic files from /class/pka into your working directory.
  • 2) Prepare your pdb file (from RCSB or NCBI...).
  • 3) Name change your pdb file to pkaS.pdb
  • 4) Edit the pkaS.pdb file (remove extra lines except for ATOM lines).
  • 5) Count number of HIS and CYS for editing pkaS-doinp.inp
  • 6) Editing pkaS-doinp.inp files based on your PDB file.
  • 7) Add H atoms using ./pkaS-addH command.
  • 8) Editing pkaS-dops.inp files for final pKa calculation.
  • 9) Run ./pkaS-dosbs > pKa.log for pKa calculation.
  • 10) Analyze the result in hybrid.out & hybrid.chart
