Connectivity across simple regulons and complex regulons. Each box represents a regulon. Simple regulons are alphabetically ordered at left. Complex regulons are ordered in increasing numbers of regulatory proteins. Connections depart only from simple regulons and arrive at complex regulons that share the same protein. In a few cases, the number of connections of a complex regulon is smaller than the number of its proteins. This is because not every regulator has a simple regulon.
