We're introducing a new series of Foldit puzzles, based on a special type of protein structure called a poly-proline helix. We're challenging Foldit players to design new proteins that incorporate this special helix!
Read more on the Foldit blog, and play Puzzle 1763: Poly-Proline Helix Design: Round 1 online now!
why such a long PP? can U perhaps give a little background on these? I may be wrong (probably am) but I thought most PP11 helices are shorter than 7 segs.
I doubt we can help science if the scientists do not help us.
I say that in the best possible taste of course (for those that remember Kenny Everet)
thx
Polyproline residues can range from 3-13 residues in length. Here is a paper about their structure and function in proteins.
