ModE molybdate transport repressor domain; ModE is a molybdate-activated repressor of the molybdate transport operon in E. coli. It consists of the domain represented by this model and two tandem copies of mop-like domain, where Mop proteins are a family of 68-residue molybdenum-pterin binding proteins of Clostridium pasteurianum. This model also represents the full length of a pair of archaeal proteins that lack Mop-like domains. PSI-BLAST analysis shows similarity to helix-turn-helix regulatory proteins.

molybdenum-pterin binding domain; This model describes a multigene family of molybdenum-pterin binding proteins of about 70 amino acids in Clostridium pasteurianum, as a tandemly-repeated domain C-terminal to an unrelated domain in ModE, a molybdate transport gene repressor of E. coli, and in single or tandemly paired domains in several related proteins.

TOBE domain; The TOBE domain (Transport-associated OB) always occurs as a dimer as the C-terminal strand of each domain is supplied by the partner. Probably involved in the recognition of small ligands such as molybdenum and sulphate. Found in ABC transporters immediately after the ATPase domain. In this family a strong RPE motif is found at the presumed N-terminus of the domain.
