Pseudomonas response regulators produced in an E. coli heterologous expression host exhibit host-derived post-translational phosphorylation

This study examines post-translational phosphorylation of Pseudomonas response regulators expressed in E. coli, finding that phosphorylation states are influenced by host factors rather than exogenous phospho-donors.

REC protein family expansion by the emergence of a new signaling pathways

The paper identifies a mechanism of REC protein family expansion through gene recombination and positive selection, leading to functional divergence in bacterial response regulators.
