I have done analysis of my protein's predicted 3D structure in PDBSum. I almost understood all analysis except the cleft analysis. Anybody have any idea, or reference on how this analysis is discussed? I could explain clefts with the amino acids they have, but is it the only interpretation of that or am I missing something?
