The DCCD-reactive aspartyl-residue of subunit C from the Escherichia coli ATP-synthase is important for the conformation of F0.

Abstract:

:The effect of various point mutations in subunits a and and c of the E. coli ATP-synthase was characterized. In each of the mutants there was no F0-dependent H+-conduction, but still an ATPase-activity comparable to wildtype activities. In addition, the subunit b could be extracted from the mutant's F0 but not from the F0 of wildtype. The effects are interpreted as a change in the conformation of F0 caused by the different mutations.

  • Role of ErbB2 in the prostaglandin E₂-induced enhancement of the mitogenic response to epidermal growth factor in cultured hepatocytes.

    abstract::Prostaglandin E(2) (PGE(2)) enhances the mitogenic response to epidermal growth factor (EGF) in hepatocytes, but the underlying mechanisms are not clear. We previously observed that PGE(2) upregulates EGF-induced signalling in the MEK/ERK and PI3K/Akt pathways in hepatocytes. Other investigations have indicated that E...
