EnvZ, a transmembrane environmental sensor of Escherichia coli K-12, is phosphorylated in vitro

Abstract

By fusing the transcriptional and translational start signals of lacZ to envZ, we have obtained high-level synthesis of a truncated EnvZ protein (EnvZ115) in which the first 38 amino acids of EnvZ are replaced with the first 8 amino acids of LacZ. Using this construct, we have partially purified the EnvZ115 protein and demonstrated that this protein can be phosphorylated in vitro. We suggest that phosphorylation may be an important feature of EnvZ function.
