Quality


Template's ligands section
Ligands in the template: FMN: 2.
Ligands in the template that will be assessed: FMN1, FMN298.
Model's ligands section
FMN1
Not all the residues interacting with the ligand are completely conserved between model and template.
No RMSD calculation will be performed.
Given the properties calculated previously, the ligand z.FMN1 will not be included in the model.
FMN1: conservation:False, RMSD:False, included: False

FMN298
All the residues interacting with the ligand are completely conserved between model and template.
The RMSD between the interacting residues of model and template is smaller than 2 Angstrom: 0.300
Given the properties calculated previously, the ligand z.FMN298 will be included in the model.
FMN298: conservation:True, RMSD:True, included: True

The new model with the included ligands was saved successfully.


Quaternary Structure Annotation of the Template
2wqf is annotated as DIMER
The oligomeric state of the structure was assigned by the authors of the corresponding PDB entry
The following biological unit was used to build the template structure: 2wqf.pdb1.gz

Quaternary Structure Modelling of the Target Protein
Analysis of evolutionary and family specific aspects revealed conservation of the oligomeric structure
Hence, the oligomeric structures of the target and the template can be assumed to be similar (=DIMER)
The corresponding reliability score is 0.784 (>0.5 indicates similarity)
Model was succesfully built as DIMER.

 - Run HHSearch to detect more templates...
 - Generate new template library
 - Run template selection against modfied template library 
 - Summarize templates: 
 - No template with A found
 - No template with B found
 - Proof template(s) selection compared to previous Repository update
 - Different number of templates selected (old0 vs new:1): model based on new templates
 - Send 1 Templates for modeling
