Abstract

The methods suggested earlier for the analysis and representation of protein structural data are now extended to the helical regions in finer details. These enable better handling of characterization of bends and distortions, for which statistical parameters are also developed. Using latest myoglobin data, best experimental parameters for the α‐helix are deduced to be r~N~ = 1.55 (0.13) Å, r = 2.28 (0.12) Å, r~C′~ = 1.70 (0.10) Å, r~0~ = 2.02 (0.12) Å, ϕ = 100.5 (2.3)°, and t = 1.495 (0.055) Å.

## 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

Chirality ("handedness") is an important feature of all biomacromolecules. In proteins the L-stereochemistry of individual amino acids influences the chirality of higher level structural features such as the right-handed helical sense of' cu-helices, the right-handed twist of P-sheets (viewed along
