The database of pre-computed isoelectric points and molecular weights for proteins and digest peptides from model organism's proteomes. Contains data for over 61 million protein sequences from 20,115 proteomes with isoelectric point predicted using 21 algorithms. Additionally, 5.38 Billion dissociation constant (pKa) predictions for proteins are available. Furthermore, it contains also proteomes digested in silico with the five most frequently used proteases (Trypsin, Chymotrypsin, Trypsin+LysC, LysN, ArgC) - in total, 9.58 Billion peptides.
