Bacteriophage T7 was irradiated in a protecting medium under nitrogen and oxygen with 60Co gamma-rays. Double-strand breaks were measured by sucrose-gradient sedimentation and by boundary-sedimentation analysis. Both methods showed that the presence of oxygen during irradiation enhanced the production of double-strand breaks. This is at variance with a recent report which suggests that boundary-sedimentation analysis does not show an effect of oxygen. The discrepancy must be ascribed to differences in interpretation of the sedimentation data.

“…Reduced 2,6-dichloroindophenol was obtained by anaerobic reduction with PdH2. Oxygen was removed from commercial nitrogen by passage through a quartz tube filled with MnO (Hersch, 1960). chromes are significantly higher than the potential of eukaryotic cytochrome c. Midpoint potentials, Ena, of +0.381 and +0.288 V were measured for the small c-type cytochrome and cytochrome c2, respectively.…”

The two c-type cytochromes of Rhodospirillum molischianum (Dus, K., Flatmark, T., deKlerk, H., and Kamen, M. D. (1970), Biochemistry 9,1984) strikingly resemble cytochrome c of eukaryotic organisms with regard to p7, absorption spectra (at 25°as well as at -190°), and circular dichroism spectra in the Soret and visible wavelength regions. In this respect they differ from previously studied c-type cytochromes (cytochromes c2) of nonsulfur purple photosynthetic bacteria. Although these findings suggest that the chemical nature of the linkages of the hemes to the respective apoproteins may be very similar in the c-type cytochromes of R. molischianum to that in eukaryotic cytochrome c, they should not be taken as evidence for similarity in protein structure surrounding these heme groups. Thus, the oxida-
