Summary

Electron spin resonance signals of dry protein samples are enhanced after ultraviolet irradiation at wavelength 3650 Å, which corresponds closely to the energy gap between valence and conduction bands.

Proteins denatured with short wave ultraviolet or 8 M urea fail to show the enhancement after irradiation at wavelength 3650 Å. This result supports the hypothesis that hydrogen bond structures are relevant in determining the semiconductor properties of proteins.
