Protein Structures

check button PDB and CIF files of the predicted protein structures
* Here we show the 3D structure of the proteins using Mol*. AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Model confidence is shown from the pLDDT values per residue. pLDDT corresponds to the model’s prediction of its score on the local Distance Difference Test. It is a measure of local accuracy (from AlphfaFold website). To color code individual residues, we transformed individual PDB files into CIF format.
