Figure 7From: Domain swapping reveals that the N-terminal domain of the sensor kinase KdpD in Escherichia coliis important for signalingSurface charge of the Usp domain within KdpD (amino acids 253–373) compared to UspC, UspF, and UspG. The tertiary structures were obtained by ESyPred3D modeling [29]. All four proteins/protein domains consist of a bundle of four to five β-sheets (blue) surrounded by four α-helices (red). Only charged amino acids are shown. The positively charged side chains are drawn in blue, the negatively charged side chains are drawn in red.Back to article page
