Chirality of Ribityl chain of FMN inverted
Hello Developers, When I built Ligand restraints using eLBOW, my resulting .pdb had an inverted chiral center in the ribityl chain of the flavin mononucleotide particularly C4'. In the database the ligand had an S configuration (correct), but after minimization and restraint generation the output had R configuration at that particular center. I wonder if there is a way to enforce the configuration for each center, although I suspect it could be a little bug, because I noticed my restraints have that center annotated as S eventhough it is R in the actual .pdb Cheers, -- Yuri Pompeu

Can you tell me or send me the inputs (off line) so I can investigate
by doing exactly what you did. Can you also tell me the PHENIX
version.

i suspect a pdb code was used. i worked around the same problems with another cofactor specifying the chirality using smiles strings. you have to double-check it anyways. -Bryan
Hi Yuri,
I'm struggling with the similar problems you coped with, is the problem
solved?
If so , how you solved it?
Thank you in advance!

Can you give me more details and the input files and commands you have
tried. Send the details to me directly.
