      User can choose one type of the following modification for browse. The statistics of the experimental verified post-translational modifications (PTMs) and the putative PTMs stored in the dbPTM resource are given in the Table3. For instance, dbPTM contains totally 12,561 known PTM sites and 772,154 putative PTM sites. The parameters of the predictive tools, KinasePhos, KinasePhos-like Sulfation and KinasePhos-like Glycosylation, for the prediction of phosphorylation sites, sulfation sites and glycosylation sites, respectively, are set as the values when the predictive specificity is 100%. The amount of putative phosphorylation sites and sulfation sites, which the ASA of the substrates are greater than 25% (defined as the residue locating at the protein surface), are 652,756 and 13,315, respectively. The total number of predicted N-link glycosylation asparagines and C-linked glycosylation tryptophanes are 33, 887 .
