Phosphoprotein phosphatase activity associated with the cytoplasmic membrane of Salmonella typhimurium and Escherichia coli.
Membrane-associated phosphoprotein phosphatase activity was demonstrated in extracts of Salmonella typhimurium and Escherichia coli. The active protein could be extracted from the membrane as a large water-soluble complex (Mr greater than 150,000). Maximal activity was observed at pH 6 to 7 in the presence of a divalent cation. The enzyme appears to be distinct from previously described phosphatases.
