Plasma membrane organization of the four protein domains of the main types of ABC transporters encountered in Actinobacillus actinomycetemcomitans and organization of the chromosomal region containing the genes encoding one particular member. The membrane-spanning domains (MSDs) and the two nucleotide-binding domains (NBDs) are depicted by ovals and triangles, respectively. When fused, domains are linked together using a large connecting area.
