Q: What is pocketZebra? A: pocketZebra is a new web-server that implements the power of bioinformatics and geometry-based structural approaches to detect and rank binding sites in proteins by their functional significance. Additionally, pocketZebra will identify a list of amino acid residues that are involved in selective binding of ligands. pocketZebra can be used to annotate functional and regulatory sites in protein families and design novel selective inhibitors/effectors. The website is free and open to all users and there is no login requirement.

Q: Why are the subfamily-specific positions (SSPs) important? A: Proteins within a single family share a common function but differ in more specific properties and can be divided into subfamilies with different specificity, enantioselectivity, stability, etc. Completely conserved positions can define general properties of the entire family (for example, have direct roles in enzyme catalytic machinery) but do not explain functional diversity. On the opposite the subfamily-specific positions (SSPs) – conserved only within protein subfamilies, but different between subfamilies – seem to be responsible for functional diversity (different substrate specificity, catalytic activity, stability, etc.) including selective binding of various substrates. SSPs can contribute to a better understanding of structure-function relationship in proteins and guide the design of novel selective inhibitors/effectors.

Q: What do I need to run pocketZebra? A: A multiple sequence alignment of a functionally diverse protein family and a representative PDB structure of one of the family members.

Q: Where can I get a multiple sequence alignment for my protein family? A: Use the Mustguseal server. Mustguseal can automatically construct large multiple alignments of protein families by collecting all available information about their structures and sequences in public databases. Multiple alignments of thousands of protein sequences and structures can be constructed using that public web-server.

Q: What do I get from pocketZebra? A: You get a list of binding sites in your protein ranked by functional significance and a list of positions in the structure that are important for selective binding of substrates/inhibitors/effectors. Both on-site and off-line versions of the output are provided.

Q: How can I cite pocketZebra? A: Please cite Suplatov D., Kirilin E., Arbatsky M., Takhaveev V., Švedas V.

Q: What is a JobID? A: pocketZebra algorithm will be applied to your input data and your results will be placed in a public directory protected by a unique 14-symbol access code (JobID). JobID can be shared with a colleague and used to access your results at any time. You can always delete your results from the public directory by pressing the "Delete job" button at the top of the results page or by sending us an e-mail request containing the JobID.

Q: I have problems starting the interactive 3D structure viewer at the results page A: pocketZebra on-line interactivity at viewing the results is currently disabled.

Q: Still have a question? A: Don`t hesitate to contact us. Contact:
