The effect of pH, ion content and ATP concentration on the change in volume was determined. A volume change greater than that attributed to ATP dephosphorylation was observed. The magnitude of the volume change of the entire system was 10−3 cm3 whereas that due to dephosphorylation was 10−6 cm3. The ratio of ATPase activity in a volume decrease to that in a volume increase was found to be approx. 10:1. The total amount of volume decrease measured approx. 0.028 cm3/g of muscle with a fresh myo fibril preparation. The volume increase which was observed upon the addition of large amounts of ATP amounted to approx. 0.036 cm3/g of muscle. The relationship between the volume changes and molecular reorganization of the myofibril proteins was discussed. It was concluded that either a large configurational change occurs in the myofibril proteins during an ATP-induced contraction or relaxation, or that the volume changes are related to the dissociation and association of actin and myosin filaments</div>","PeriodicalId":100169,"journal":{"name":"Biochimica et Biophysica Acta (BBA) - Specialized Section on Biophysical Subjects","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1964-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0926-6577(64)90095-6","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"23802382","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}
