Molybdate transport and regulation in bacteria.
Grunden A.M., Shanmugam K.T.
Molybdate is transported in bacteria by a high-affinity transport system composed of a periplasmic binding protein, an integral membrane protein, and an energizer protein. These three proteins are coded by modA, modB, and modC genes, respectively. The ModA, ModB, and ModC proteins from various org ... >> More
Molybdate is transported in bacteria by a high-affinity transport system composed of a periplasmic binding protein, an integral membrane protein, and an energizer protein. These three proteins are coded by modA, modB, and modC genes, respectively. The ModA, ModB, and ModC proteins from various organisms (Escherichia coli, Haemophilus influenzae, Azotobacter vinelandii, and Rhodobacter capsulatus) are very similar. The lowest Km value reported for molybdate in the molybdate transport process is approximately 50 nM. In a mod mutant, molybdate is transported by the sulfate transport system or by a nonspecific anion transporter. Molybdate transport is tightly coupled to utilization in E. coli and Klebsiella pneumoniae, while other dinitrogen-fixing organisms appear to have a molybdenum storage protein. In all organisms studied so far, molybdate transport genes are regulated by a repressor protein, ModE. The ModE-molybdate complex binds to the sequences TAYAT (Y = T or C) in the operator/ promoter region in E. coli and prevents transcription of the modABCD operon. The ModE-molybdate complex binds to DNA as a homodimer in E. coli and possibly in other organisms as well. In R. capsulatus, however, two ModE homologues (MopAB proteins) are required for repression. << Less

Molybdate transport.
Self W.T., Grunden A.M., Hasona A., Shanmugam K.T.
In both bacteria and archaea, molybdate is transported by an ABC-type transporter comprising three proteins, ModA (periplasmic binding protein), ModB (membrane protein) and ModC, the ATPase. The modABC operon expression is controlled by ModE-Mo. In the absence of the high-affinity molybdate transp ... >> More
In both bacteria and archaea, molybdate is transported by an ABC-type transporter comprising three proteins, ModA (periplasmic binding protein), ModB (membrane protein) and ModC, the ATPase. The modABC operon expression is controlled by ModE-Mo. In the absence of the high-affinity molybdate transporter, molybdate is also transported by another ABC transporter which transports sulfate/thiosulfate as well as by a nonspecific anion transporter. Comparative analysis of the molybdate transport proteins in various bacteria and archaea is the focus of this review. << Less
