title: Monoclonal antibodies against subunits of yeast mitochondrial H+-ATPase.
abstract: Fourteen stable lines of myeloma-spleen cell hybrids producing antibodies against the mitochondrial H+-ATPase have been isolated. One reacted with the alpha-subunit of the enzyme complex (Mr 56000), nine with the beta-subunit (Mr 54000), and four with a 25 kDa subunit which has not been previously characterized. These antibodies are inhibitory or stimulatory or have no effect upon the enzyme activity. Two of the monoclonal anti-beta-subunit antibodies were found to be particularly effective in immunoprecipitating intact H+-ATPase complex.
