STING_DB is composed of structural, sequence, function and stability parameters/descriptor for protein analysis. This database operates with a collection of both publicly available data (PDB, HSSP, Prosite) and its own data (contacts, interface contacts, surface accessibility). STING_DB is one of the best known databases of structural parameters reported in per-residue fashion with over 300 of them compiled at a single site.
Considering its relevance for researchers interested in protein analysis, the module Sting_DB Quality Assessment (QA) was designed to measure the quality of the data deposited in the Sting_DB. On a weekly basis, a checklist procedure is performed to identify the parameters/files that are both missing and/or empty for the new PDB files added to the database. The main goal of such a procedure is to guarantee that the quality of the data will not be degraded as the updates take place. When the checklist procedure identifies a group of parameters that are missing and/or empty, a report is automatically sent to the Sting_DB administrator who will run a set of scripts to update the parameters concerning the new PDB files, and subsequently, perform the checklist procedure to evaluate the quality of the updated data.
