ID 1
Refinement Space ?
Refinement Protocol FLEXIBLE FIT
Refinement Target ?
Overall B Value ?
Fitting Procedure ?
Details Used AlphaFold model as initial model (Q5S007) using only the ROC domain. TUB1 was added to the initial refinement to prevent ROC model from entering density reserved for the microtubule. TUB1 was discarded after the initial refinement.
