The characterization of lysine lactylation (Kla) in prokaryotes remains unclear. Here, the authors identify the regulatory enzymes (YiaC as a lactylase and CobB as a delactylase) and functional network of Kla and reveal a Kla-mediated molecular mechanism for glycolysis regulation in Escherichia coli.
