Homology Modeling
Fallback Data
Here are results from a homology modeling exercise using SwissModel, as a fallback for technical problems with the assignment i.e network problems or other issues with the program or input data.
Contents
Target sequence
This is just one of the reference species' sequences - I chose Mbp1_SCHPO because it is the most distantly related to saccharomyces cerevisiae.

FASTA formatted target-template alignment
This uses the 1BM8 PDB file as template.

There are no gaps and the sequences align over the whole length. If the sequences were of different length, the shorter one would have to be padded with gap characters: "-".
SwissModel response
Explanation of the output is found in the SwissModel Help page.
Graphical comparison of template and target sequence to emphasize which regions have been modelled. Given the good, full-length alignment, SwissModel had no problem modeling the entire protein.
Model QMEAN score vs. expected QMean scores of protein structures, as a function of domain size. The model (red cross) is within the lower 2 sigma range in quality for its size.
Cartoon view of the model, colored by QMEAN scores
The target-template alignment:
