If the correct atoms are in place, resetting the b factors of those atoms/residues to a constant e.g. 5.00 and refining in phenix with individual B-factors ON should take care of these.Best,RezaSent from my iPhoneOn Aug 2, 2023, at 7:42 AM, Thomas, Leonard M. wrote:

Hello, is it definitely due to the TLS refinement? I guess you have tried
without TLS and don't see the same effect i.e. the B-factors are more
consistent. It would be good to know.

if the B-factor anomaly remains.

So the Phosphates are actually the end of the ADP which the Sulfer atoms are
Cystiene suffers. The Fo-Fc maps show large positive peaks for each position
also. The TLS groups is the whole protein chain, there are 4 in the asymmetric
unit as the biological unit I think is a dimer of 2
One possible explanation for high B-factors, assuming the coordinates are
refined correctly, is partial occupancy and high mobility (dynamics) at
those heavy atom sites.
Also, one should check Fo-Fc maps of those positions. Are other atom types
substituting for some of those heavy atoms (such as
You need to tell us more details - is this a deposited structure?

Hello All,
A general questions though phenix.refine is being used for refinement. A
student I am working with has a structure that was solved and initially refined
using TLS and NCS parameters. They were given the structure to gain some
experience in refinement and they have been asking me
