Mustguseal

Server for Multiple Structure-Guided Sequence Alignment of Protein Families

Mustguseal can automatically construct large structure-based sequence alignments of functionally diverse protein families that include thousands of proteins based on all available information about their structures and sequences in public databases

to help at studying a protein function and regulation, designing improved enzyme variants for practical application and selective modulators of enzyme functional properties

The Mustguseal FAQs:


What is Mustguseal?
Mustguseal stands for Multiple Structure-Guided Sequence Alignment.
Mustguseal is a bioinformatic protocol designed to build large alignments of functionally diverse protein families and a web-platform to provide a user-friendly web-based interface to the Mustguseal protocol through the World Wide Web. Mustguseal can be used to build focused alignments of the selected protein families or superimpose a large collection of related proteins within a superfamily. This server is capable of constructing multiple alignments of functionally diverse families that include thousands of proteins basing on all available information about their structures and sequences in public databases. In addition, three integrated web-servers are available to further study the obtained alignments. You should see the Presentation of the Mustguseal server for more information.


How Mustguseal works?
The Mustguseal protocol implements structure similarity search to collect evolutionarily remote relatives, which are expected to represent different protein families. Then, for each collected evolutionarily remote relative, Mustguseal runs a sequence similarity search to collect evolutionarily close relatives - members of the corresponding families. In such a way Mustguseal takes into account variability of sequences and structures within a large superfamily to obtain a set of functionally diverse homologous proteins. A combination of structure and sequence alignment procedures is then implemented to build the final multiple alignment.


What software is required to use Mustguseal?
All steps of the Mustguseal protocol are executed entirely on the server side. You do not need any specific software on your side.
The Analysis section of the Results page offers interactive content for sequence and structure analysis. Interactivity is implemented in HTML5 and therefore no plugins nor Java are required. The only prerequisite for using the Analysis section of the Results is a HTML5-compatible web-browser. Current versions of all major browsers support HTML5 as the default standard.

What web-browser is required to use Mustguseal?
The Mustguseal web-server is not browser-specific. You would need an HTML5-compatible web-browser to use the Analysis section of the Results. To ensure the HTML5-compatibility upgrade your current browser to the latest version.

The server has been successfully tested for compatibility with the following browsers:

Please note that we have had compatibility issues with the Microsoft Internet Explorer and therefore this browser is currently not supported by the Mustguseal.

How can a Mustguseal alignment help in your research?
You should use sister web-servers of Mustguseal to further study the obtained alignments:

  • the Zebra web-server to identify variable amino acid residues responsible for functional diversity and to select hotspots for directed evolution or rational design experiments;

  • the pocketZebra web-server to identify and rank binding sites in proteins by functional significance and select particular positions in the structure that are important for selective binding of substrates/inhibitors/effectors;

  • the visualCMAT web-server to select and interpret correlated mutations/co-evolving residues in protein families.

Implementation of Mustguseal, Zebra, pocketZebra, and visualCMAT in the laboratory practice can help at studying mechanisms of protein action, designing enzymes with improved properties for practical application and selective modulators of activity of the wild-type proteins.
