ATP hydrolyzing activity (ATPase activity) was associated with the BBMV.

The enzyme also hydrolyzed ITP and GTP but not p-NPP, ADP, or AMP. KNO3 and NEM strongly inhibited the ATPase activity. Behaviours of the ATPase against inhibitors suggested that it resembled vacuolar type ATPase.","PeriodicalId":7729,"journal":{"name":"Agricultural and biological chemistry","volume":"24 1","pages":"2693-2700"},"PeriodicalIF":0.0,"publicationDate":"1991-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85974327","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}

One fraction (Alb-1) was extracted with 0.5m NaCl or water when used as the first solvent. Another fraction (Alb-2) was extracted with water after removing Alb-1 and globulin. Apparent pIs of Alb-1 and Alb-2 were 4.5–7.5 and 5–6, respectively. Alb-2 was precipitated by various metal ions (1 mm), while Alb-1 was not. Alb-2 contained four major components (Mr = 56, 36, 26, 22 kD), although Alb-1 had no particular major proteins. Pronase treatment of amaranth flour before protein extraction decomposed Alb-1, but not Alb-2, as seen by SDS-PAGE analysis. The findings that Alb-2 was protected from the Pronase treatment and it could not be extracted until Alb-1 and globulin were removed suggests that Alb-2 might be associated with protein bodies [Irving et al., J.
