N-Cap And C-Cap Residues In Strands In Beta-Hairpins

Hi,

I want to know what exactly are the N-cap of C-cap residues in a beta-hairpins. Actually I found a paper about this, but I am not able to understand clearly, what are the N-cap and C-cap residues ?? Here's a link to my problem ... https://www.dropbox.com/s/azry1zydqovexjs/pic.png

Thanks

To my knowlege, a N-cap or C-cap residue is the aminoacid found at the N-terminus and C-terminus, respectively.

From your figure, I am not really sure if any of them are considered as N-cap or C-cap residues, though I may be wrong.
