Glutamylation of Bacterial Ubiquitin Ligases by a Legionella Pseudokinase

Trends Microbiol. 2019 Dec;27(12):967-969. doi: 10.1016/j.tim.2019.09.001. Epub 2019 Oct 14.

Abstract

Legionella pneumophila encodes a family of phosphoribosyl ubiquitination ligases (SidE) essential for the bacterium to establish successful infection. Four independent studies now show that the SidE family of ubiquitin ligases are regulated by a novel mechanism of glutamylation via a pseudokinase-like Legionella effector, SidJ, in an ATP- and calmodulin-dependent manner.

Keywords: SdeA; SidE; SidJ; calmodulin; phosphoribosyl ubiquitination; post-translational modification.
