Y, namely 1SRM, 1SHG, and 1FYN (see Supplementary Figs. S1 and S2). CO profile CO is one property of proteins that is well-known to be correlated with folding kinetics. The CO profile, which was discussed above, is an extension of the CO; the cumulative number of native contacts ck , is plotted against residueresidue distances along a chain, k. This profile provides information about the respectiv
