From: Detection of protein catalytic residues at high precision using local network properties

  F 1 F 2 Precision Coverage

  1. Calculations were run over the residue interaction networks derived from the 226 protein structures from our extended test set. Scoring functions used here are described in Methods. Values for precision and coverage were obtained over the whole set. F1 and F2 respectively represent the F-measure defined in Methods when using β = 1 and β = 2. a As proposed by Amitai [14]. RSA: residue surface accessibility. bResidues were considered as catalytic if their MDev value for the scoring function defined in Equation 1 was superior to the indicated threshold value. Corresponding 'specificity' (equal to (p-, r-)/r-) values were 97.80% at MDev1, 99.68% at MDev2, and 95.57% when using closeness combined to RSA.
