Sequence homology between two membrane transport ATPases, the Kdp-ATPase of Escherichia coli and the Ca2+-ATPase of sarcoplasmic reticulum

J E Hesse et al. Proc Natl Acad Sci U S A. 1984 Aug.

Abstract

We have determined the DNA sequences of the genes encoding the three structural proteins of the Kdp-ATPase, an ATP-driven potassium transport system of Escherichia coli. Regions of the predicted amino acid sequence of KdpB, the phosphorylated protein of the system, are homologous to regions of the Ca2+-ATPase of rabbit sarcoplasmic reticulum. The phosphorylated aspartate residue of the latter is within a region of homology.
