This HMM describes the permease protein, ModB, of the molybdate ABC transporter. This system has been characterized in E. coli [1], Staphylococcus carnosus [2] Rhodobacter capsulatus [3] and Azotobacter vinlandii [4]. 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.
