Legionella pneumophilais a facultative intracellular pathogen responsible for legionellosis, a severe lung disease in humans. This bacterium uses a type 4b secretion system to deliver various effector proteins into the cytoplasm of a eukaryotic target cell. Among those is the glucosyltransferase Lgt1. This effector modifies serine-53 in eukaryotic elongation factor 1A (eEF1A) by mono-O-glucosylation. Modification of eEF1A results in inhibition of protein synthesis and death of the eukaryotic cell, processes which are thought to contribute toLegionellainfection. Here we describe a protocol for isolation of the glucosyltransferase Lgt1 fromL. pneumophilaculture followed by assaying its enzymatic activity using14C-UDP-glucose autoradiography.
