Men operon in E. coli. Part of the ubiquinone biosynthetic pathway is shown on the left. The genomic region containing this operon is shown on the right. Inside the enzyme nodes (rectangle) of the pathway, the names of the matched genes are shown in brackets, e.g., b2264 encodes a bifunctional protein with two enzymatic activities (Palaniappan et al. 1992). The gene filled with gray (b2263) encodes a product that is currently annotated as a hypothetical protein.
