Bacterial lipoproteins are characterized by fatty acids that are covalently attached to their amino terminus via posttranslational modification in the cytoplasmic membrane. Three enzymatic steps are involved in the synthesis of mature triacylated lipoprotein: prolipoprotein converts into diacylglyceryl-prolipoprotein that in turn converts into apolipoprotein, which is finally converted into mature triacylated lipoprotein. Here we describe the detection of one of these intermediate forms of lipoprotein, diacylglyceryl-prolipoprotein, using (3)H-palmitate labeling and inhibition by globomycin and detection by fluorography.
