The following limits are in effect:
We have generated protonated forms in 3 pH ranges. The reference structure ("ref") is a single representative structure at pH 7. The middle pH range ("mid") contains additional protonated forms obtained by titrating protons with pKa between 5.75 and 8.25. The low pH range ("lo") contains additional protonated forms between pH 4.5-7 and the high pH range ("hi") contains additional protonation forms between pH 7-9.5. Databases are divided into chunks for easier download. mol2 and sdf slices are 100MB or less uncompressed. Flexibase are 160MB or less uncompressed. To download all files in the usual pH range (5.75-8.25) use "Usual". To download databases for metalloenzymes use "Metal", which adds the pH range 7-9.5 to usual above. For the entire pH range 4.5-9.5 please use "All". We also offer tables of Molecular Properties, purchasing information, and Inchi files. A product of
