Finding the ligand you’re looking for in the PDB can be a bit tricky. I believe you’re looking for TCE: http://www4.rcsb.org/ligand/TCE Which I found by searching for its IUPAC name: 3,3',3''-phosphanetriyltripropanoic acid
If that fails, you can usually find the SMILES string for your ligand and then search for that at using: http://www.rcsb.org/pdb/ligand/chemAdvSearch.do Cheers michael From: CCP4 bulletin board <CCP4BB@JISCMAIL.AC.UK<mailto:CCP4BB@JISCMAIL.AC.UK>> on behalf of Alex Lee <alexlee198...@gmail.com<mailto:alexlee198...@gmail.com>> Reply-To: Alex Lee <alexlee198...@gmail.com<mailto:alexlee198...@gmail.com>> Date: Thursday, 19 October 2017 at 11:19 To: "CCP4BB@JISCMAIL.AC.UK<mailto:CCP4BB@JISCMAIL.AC.UK>" <CCP4BB@JISCMAIL.AC.UK<mailto:CCP4BB@JISCMAIL.AC.UK>> Subject: [ccp4bb] PDB ligand 3-letter code for TCEP? Hi All, I tried to look for the 3-letter ligand for reducing reagent TCEP in PDB but I could not find one. I even search with "Tris(2-carboxyethyl)phosphine hydrochloride" in PDB but got right hit. How do I need to to to pull the TCEP code out?
