Loss of fluorescence during initial stages of iodination of ribonuclease S was identical with that observed for ribonuclease A. These results indicate that ribonuclease A and ribonuclease S are very similar in general conformation and that each has a minimum of 3 and possible 4 tyrosyl residues initially susceptible to iodination. During more extensive iodination of ribonuclease S, the molecule dissociated into S-peptide and iodinated S-protein. These results suggest that extensive iodination of a protein may not be a reliable guide to the number and identity of exposed tyrosyl residues in the native molecule.</li><li>2.2. Iodination of S-protein gave a loss of fluorescence similar to that observed for urea-denatured ribonuclease A; the results indicate that all six tyrosyl residues of S-protein are susceptible to iodination as though the structure were more open than for ribonuclease A or ribonuclease S.</li><li>3.3.

The effects on the time course of many factors (addition of photosynthetic inhibitors, Hill oxidants, heat treatment, light intensity, pre-illumination and background light) were investigated. Inhibitors such as 3(4′-chlorophenyl)-1,1-dimethylurea, and o-phenanthroline caused the same remarkable effect on the time course, which was different from that caused by heat treatment of the chloroplasts. The back flow of electrons, which was considered in the analysis of steady-state fluorescence in our previous paper, is also taken into consideration in the present study. A scheme is proposed to account for the findings with respect to the fluorescence during the induction period. The quantity “work integral” is introduced to correlate the observed lowering of fluorescence during the induction period with the utilization of the absorbed light energy. The concentrations of the oxidation-reduction substances in the scheme were estimated from the “work integral” obtained under varied experimental conditions.</div>","PeriodicalId":100158,"journal":{"name":"Biochimica et Biophysica Acta (BBA) - Biophysics including Photosynthesis","volume":"120 1","pages":"Pages 23-33"},"PeriodicalIF":0.0,"publicationDate":"1966-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0926-6585(66)90273-1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17033676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
