Membrane Adenosine Triphosphatase from Streptococcus faecalis
The membrane adenosine triphosphatase from SfrepfoCOCCUS faecalis has been purified by heat treatment, gel filtration through Agarose, and repeated chromatography on diethylaminoethyl cellulose. The purified ATPase appears to be homogeneous as judged from gel electrophoresis and sedimentation velocity studies. Sedimentation equilibrium studies, which are presented in the succeeding paper, also ...
متن کاملInhibition of membrane-bound adenosine triphosphatase and of cation transport in Streptococcus faecalis by N,N'-dicyclohexylcarbodiimide.
N, N’-Dicyclohexylcarbodiimide (DCCD) was found to be a potent inhibitor of the membrane-bound ATPase of Sfrepfococcus foe&is but did not inhibit the solubilized form of the enzyme. Inhibited membrane-bound ATPase was reactivated by releasing the enzyme from the membrane. Conversely, sensitivity to DCCD was restored by reconstituting the ATPase-membrane complex from solubilized ATPase and deple...

متن کاملAdenosine triphosphate pool during the growth cycle in Streptococcus faecalis.
Forrest, W. W. (University of Adelaide, Adelaide, South Australia). Adenosine triphosphate pool during the growth cycle in Streptococcus faecalis. J. Bacteriol. 90:1013-1018. 1965.-The adenosine triphosphate (ATP) pool has been studied throughout the growth cycle of Streptococcus faecalis. Normally, the pool is quantitatively related to the concentration of organisms and the growth rate, but de...
متن کاملCharacterization of plasma membrane adenosine triphosphatase of Neurospora crassa.
It has been proposed (Slayman, C.L., Long W.S., and Lu, C.Y.-H. (1973) J. Membr. Biol. 14, 305--338) that in Neurospora crassa, a plasma membrane ATPase functions to pump H+ ions out of the cell, thereby generating an electrochemical gradient that can drive transport processes. Using the concanavalin A method of Scarborough (Scarborough G.A. (1975)J. Biol. Chem. 250, 1106--1111), we have prepar...
