Model for the role of TusA in E. coli. A, the involvement of IscS in sulfur transfer under anaerobic conditions in E. coli wild type cells. B, sulfur transfer under aerobic conditions in the absence of TusA. C, sulfur transfer under anaerobic conditions in the absence of TusA. The model describes the data obtained from the microarray analysis with a focus of the effect on Moco biosynthesis and molybdoenzyme activities. A detailed description of the model is given in the text (under “Discussion”).
