Currents in biochemical research, 1956; twenty-seven essays charting the present course of biochemical research and considering the intimate relationship of biochemistry to medicine, physiology, and biology. Biochemistry -- Research. ENZYME-SUBSTRATE COMPOUNDS indicates that cytochrome c is above h in the respiratory chain in- volved in oxidative phosphorylation. Slater's factor (41, 63) is adequately described in non- phosphorylating preparations as the component linking flavo- protein to cytochrome c that is sensitive to BAL. But in phos- phorylating preparations it has recently been found (7) that cytochrome h links flavoprotein to cytochrome c (or c^ in both the DPNH and succinate-linked systems, and (2) that the + 0.02-. 490 530 570 / (rnp) Fig. 3. The spectroscopic changes in an aerobic mitochondrial suspen- sion caused by addition of excess antimycin-A. Mitochondria were suspended in a reaction medium that contained all substances necessary for oxidative phosphorylation except phosphate ac- ceptor. The base line of the figure corresponds to the material before anti- mycin-A treatment, the curve, just following the treatment. The peak at 563 m/i is caused by the reduction of cytochrome b, the trough at 550 m^, by the oxidation of reduced cytochrome c (460-1-2). sensitive point lies between cytochrome h and the component above it in the respiration chain (probably cytochrome c^. Thus, in the phosphorylating system, cytochrome h fulfills the requirements for Slater's factor. The minimum hypothesis for an explanation of the effect of these inhibitors in the intact system is that they affect the reaction h" + c'" > h'" + c" (9) 321.
