Figure 6
Superposition of computational models with the O1 form crystal structure model of PsiM. In the absence of an anchoring template beyond the Rossman fold enzyme core, the pre-AF homology model (red) delivers a random conformation for the SRL, while AF2 (cyan) provided with low confidence a similarly unstructured SRL conformation. AF3 delivered two slightly different models, one with an open-loop conformation (purple) while the alternative AF3 model (blue) partly follows the experimental O1 model (green). As is the case for X-ray models, the ensemble of various computational models emphasizes that the uncertainties of the models in the SRL are larger than each single prediction model suggests. |
