molybdate ABC transporter, permease protein This model describes the permease protein, ModB, of the molybdate ABC transporter. This system has been characterized in E. coli, Staphylococcus carnosus, Rhodobacter capsulatus and Azotobacter vinlandii. Molybdate is chemically similar to sulfate, thiosulfate, and selenate. These related substrates, and sometimes molybdate itself, can be transported by the homologous sulfate receptor. Some apparent molybdenum transport operons include a permease related to this ModB, although less similar than some sulfate permease proteins and not included in this model.
