Lipid biosynthetic genes and a ribosomal protein gene are cotranscribed.

By using insertional mutagenesis we demonstrated that the rpmF gene encoding ribosomal protein L32, the plsX gene encoding a protein involved in membrane lipid synthesis and several fatty acid biosynthetic genes (fabH, fabD and fabG) are cotranscribed. Organization of these genes into an operon may play a role in the coordinate regulation of the synthesis of ribosomes and the cell membranes.
