Substrate-binding clusters of the K+-transporting Kdp ATPase of Escherichia coli investigated by amber suppression scanning mutagenesis.

The Journal of biological chemistry - 30 Mar 2001

Dorus S, Mimura H, Epstein W

Abstract excerpt

The Kdp-ATPase of Escherichia coli is a four-subunit P-type ATPase that accumulates K(+) with high affinity and specificity. Residues clustered in four regions of the KdpA subunit of Kdp were implicated as critical for K(+) binding from the analysis of mutants with reduced affinity for K(+) (Buurman, E., Kim, K.-T., and Epstein, W. (1995) J. Biol. Chem. 270, 6678-6685). K(+) binding by this pump has been analyzed...
