Protein Family Models

The alignments cover the most conserved region of the proteins, which is thought to be located in a cytoplasmic loop between two transmembrane domains. The members of this family have a variable number of transmembrane helices. (from Pfam)

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.

molybdate ABC transporter permease is the transmembrane subunit (TM) found in periplasmic binding protein (PBP)-dependent ATP-binding cassette (ABC) transporter for molybdenum, and is responsible for the translocation of the substrate across the membrane
