FIG. 6.

Genetic organization of the lic region and functions of the gene products. (A) The lic region contains eight genes with functions in teichoic acid synthesis. The promoters of the lic1 operon (with the tarI, tarJ, licA, licB, and licC genes) and the lic2 operon (with the tacF, licD1, and licD2 genes) are shown as arrows. The functions of the gene products are written below the gene(s). (B) Roles of the gene products in the formation of the teichoic acid precursor and its transport across the membrane. CM, cytoplasmic membrane; P, phosphate residue.
