FIG 5 .

Schematic representation of different modes of environmental sulfur uptake and utilization within the Novosphingobium genus. The three different routes for sulfur assimilation are shown. Sulfur assimilation as inorganic sulfur (sulfates and thiosulfates) (A), via ssuABC (transport system) and ssuD (FMNH₂-dependent alkane sulfonate monooxygenase) (B), and via taurine transport and metabolism by tauABC (transport system) and tauD (taurine dioxygenase) (C). APS, adenosine phosphosulfate; PAPS, phosphoadenosine phosphosulfate; SUOX, sulfite oxidase.
