Protein Structure Prediction

RaptorX is a protein structure prediction server developed by Xu group, excelling at predicting 3D structures for protein sequences without close homologs in the Protein Data Bank (PDB). Given an input sequence, RaptorX predicts its secondary and tertiary structures as well as solvent accessibility and disordered regions. RaptorX also assigns the following confidence scores to indicate the quality of a predicted 3D model: P-value for the relative global quality, GDT (global distance test) and uGDT (un-normalized GDT) for the absolute global quality, and RMSD for the absolute local quality of each residue in the model. RaptorX-Binding is a web server that predicts the binding sites of a protein sequence, based upon the predicted 3D model by RaptorX. More details can be found here:

News and updates

System Under Maintenance | 2015-09-30 09:27:50

The computing systems running the servers are under maintenance, so your jobs will be delayed. However, you can still submit new jobs to the servers.

Retrieve Jobs By Their Sequences | 2015-08-12 05:58:42

Sometimes users cannot receive the email notifications upon completion of their jobs due to various reasons. Now users can retrieve jobs by their sequences so that they do not have to keep a record of the job IDs. However, only sequences submitted in the past 60 days can be retrieved since after 60 days it is better to re-predict their sequences, which may result in a better result due to database enlargement.

Contact Server Suspended | 2015-01-31 19:42:06

The server machine running the contact server jobs has a dead hard drive. We will have to install a new hard drive, the operating systems and all the code needed for the contact server, which will take at least one week. However, users can still submit their contact prediction jobs and access the results of previous jobs.
