566: CASP10 Target T0691

Summary

Name:

Status:

Closed

Created:

05/30/2012

Points:

100

Difficulty:

Intermediate

Description:

The seventh CASP10 target is not an easy one, as it's 163 residues and we don't have any alignments for the first 18 residues. We are providing you with 5 different templates, but all of them have a similar topology (that we hope is the correct one!). We will provide you with server predictions once they are released. More details about this CASP target are in the puzzle comments.

Additional info about this CASP target

Here is the CASP link for this target (showing the amino acid sequence):
http://predictioncenter.org/casp10/target.cgi?id=92
____________________________________________________

Here is the sequence logo predicted by the SAM server.

H = helix
E = sheet
C = loop (or coil)

The taller the letter at each position, the higher the probability of that specific secondary structure for that amino acid.

For example, the Leucines at residues 10, 14 & 15 are highly predicted to be in a helix. However, the Leucines at residues 62, 115, 125 & 127 are predicted to be sheets.

The first 18 residues are predicted to be in a helix

The N-terminal region of this CASP10 target is unaligned to any of the 5 templates we have given you, but it is predicted to be helical.

Here is a hint to easily make a helix (if that is what you want to attempt):

The rebuild tool takes structure assignment into account, so you can set the secondary structure to helix and then Rebuild. Foldit will then make a helix out of that region.

is there a problem?

Sorry, was waiting on the update to devprev:

It should be up now, we were waiting on the update to devprev:
http://fold.it/portal/node/992806

specifically this bugfix:
Alignment Tool -
* Secondary structures are now assigned when threading

since this will make it easier when threading the template for this CASP10 target, due to the beta barrel topology: http://en.wikipedia.org/wiki/Beta_barrel
