'''Catabolite control protein''' (CcpA) is a regulator of carbon metabolism in gram-positive bacteria. When high concentrations of glucose-6 phosphate or fructose-1,6-diphosphate are present in the cell, they phosphorylate proteins HPr or Crh which interact with CcpA. The latter binds to DNA operator to modulate transcription.<ref>PMID:16321938</ref> | '''Catabolite control protein''' (CcpA) is a regulator of carbon metabolism in gram-positive bacteria.
