title: Immunochemical evidence for an active (F1-F0)-ATPase in mycoplasmas.
abstract: In all Acholeplasma, Mycoplasma and Spiroplasma species tested, a protein capable of reacting with antibodies prepared against the beta subunit of the proton-ATPase complex from yeast, chloroplasts and Escherichia coli was detected. The reactive protein of M. gallisepticum was found to be catalytically active, suggesting that mycoplasmas, as other bacteria, possess a proton-translocating ATPase. Characterization of the ATPase activity of M. gallisepticum indicates that this organism also possesses a Na+-stimulated ATPase activity that differs from the proton-ATPase in its pH profile and its resistance to dicyclohexylcarbodiimide (DCCD).
