SagS is a hub protein, connecting multiple overlapping signaling system, to enable the transition from a planktonic to a sessile, drug tolerant mode of growth.?, unknown, Arrows and blunt-ended lines indicate stimulatory interactions and inhibitory interactions, respectively. Dashes lines indicate modulation of c-di-GMP levels. Confirmed SagS interaction partners are shown in red.
