Mining PSI Structures:JCSG Ligand Server Abhinav Kumar Structure Determination Core
Outline • Introduction and history • Examples of use (live) • Statistics • Unique ligands • Binding mode studies • Usage
Introduction and History http://smb.slac.stanford.edu/public/jcsg/cgi/jcsg_ligand_check.pl • Herb’s compilation of JCSG data • Porting Excel sheet to Web server • Automating tasks • Andrew’s script to produce the list of PSI structures released by PDB • Script to download the pdbs and extract relevant information • Database for the Ligand server
Live • Examples of query entry • Executing search • Explanation of links in the search results • Summary

Examples of Unique Ligands (R)-2-Hydroxy-3-Sulfopropanoic acid (3SL) bound to the putative 2-phosphosulfolactatetitle 2 phosphatase from Clostridium Acetobutylicum (1VR0) Indole-3-Carboxaldehyde (I3A) bound to tellurite resistance protein of COG3793 (ZP_00109916.1) from Nostoc Punctiforme PCC 73102 (2OU3) 10-Oxohexadecanoic acid (OHA) bound to Ferredoxin-like protein (JCVI_PEP_1096682647733) from an environmental metagenome (unidentified marine microbe) (2OD6)
Unknown Ligands (UNL) FB8805A (2Q9K) Protein of unknown function FK9436A (2OH1) Acetyltransferase Gnat family
Binding Mode Studies • Several ligands/co-factors bound to the proteins • Binding mode studies for co-factors • FMN as an example • FMN bound in over 340 structures in RCSB • Binding mode variation in due to the torsional flexibility in the molecule
