Abstract

Experimental data are summarized on decay kinetics of uv‐induced paramagnetic centers in globular proteins. The PC decay rate in the absence of oxygen in α helical regions is shown to differ always by about two orders from that in nonhelical regions of the polypeptide chain. This effect can be utilized to estimate the degree of α helicity in the dry state, in solution, and in the frozen solution of proteins.

Reduced lattice models of the three de novo designed helical proteins ␣ 2 , ␣ 2 C, and ␣ 2 D were studied. Low temperature stable folds were obtained for all three proteins. In all cases, the lowest energy folds were four-helix bundles. The folding pathway is qualitatively the same for all proteins
