SWISS-MODEL

SWISS-MODEL workspace was published by Arnold et al. in 2005. <ref> Arnold K., Bordoli L., Kopp J., and Schwede T. (2006). The SWISS-MODEL Workspace: A web-based environment for protein structure homology modelling. Bioinformatics, 22,195-201.</ref>

Usage - Automated Mode

The automated mode should only be used, if target and template share more than 50% of sequence identity. This is not the case for the proteins selected as target in this case. Therefore the Alignment Mode will be used to create the models for glucocerebrosidase.

Usage - Alignment Mode

To create the Alignments needed as input, the tool ClustalW was used.

2WNW

Using the standard output alignment of ClustalW, the workunit of Swiss-Model got aborted: too many unfruitful attempts to rebuild a loop were tried. This indicates, that the alignment is not good and that it has to be adjusted.
