Respiratory burst oxidase activation can be dissociated from phosphatidylinositol bisphosphate degradation in a cell-free system from human neutrophils.


Activation of the respiratory burst oxidase in cell-free preparations from 32P-labeled neutrophils was compared with changes in levels of radioactively labeled phosphoinositides in the same preparations. With membrane particles, treatment with sodium dodecyl sulfate (SDS) in the presence of cytosol led to activation of the oxidase without an alteration in… (More)
