PINE SPARKY.2 for automated NMR based protein structure research

PMCID: 5925765
PMID: 29281006
DOI: 10.1093/bioinformatics/btx785
call_split See protocol

[…] s the status file from the URL associated with the Key, and the PINE web server updates the status of the PINE job in the status file. Predictions of secondary structures (PECAN), referencing errors (LACS), hydrophobicities (PACSY), torsion angles and flexibilities (TALOS-N), and 3 D structures (CS-ROSETTA) are executed sequentially by BASH and PYTHON scripts based on the chemical shifts with the […]

[…] uns yield reliable backbone assignments for more than 90% of the amino acid residues and reliable side chain assignments with greater than 75% completeness. The assigned data are then run through the LACS [] (Linear Analysis of Chemical Shifts) software, which corrects possible referencing problems and identifies assignment outliers. The software package PECAN [] (Protein Energetic Conformational […]
