Abstract
A His-Asp/Glu dyad forms the core of EnvZ histidine kinase (HK) osmosensing wherein osmolytes mediate changes in the backbone and side-chain microenvironment, leading to enhanced histidine autophosphorylation. This His-Asp/Glu dyad is highly conserved across diverse HKs, suggesting a unified model for integrating diverse environmental stimuli to a singular histidine phosphorylation response.
