Transcriptional regulator (MerR family); Global transcriptional regulator that activates transcription of bmr and blt by binding directly to their promoter. Stimulates also the expression of the mta gene itself, ydfK and ymfE.

Putative divalent cation efflux transporter; Primary efflux pump for manganese. May prevent manganese intoxication; Belongs to the cation diffusion facilitator (CDF) transporter (TC 2.A.4) family.

anti-TRAP regulator; By forming a complex with tryptophan-activated TRAP, and masking its RNA binding site, it inhibits TRAP's RNA binding ability, thereby abolishing TRAP regulation of gene expression, leading to antitermination and increased trp operon expression. AT acts by competing with messenger RNA for the RNA binding domain of TRAP.

Co-factor of molecular chaperone; Participates actively in the response to hyperosmotic and heat shock by preventing the aggregation of stress-denatured proteins and by disaggregating proteins, also in an autonomous, DnaK-independent fashion. Unfolded proteins bind initially to DnaJ; upon interaction with the DnaJ-bound protein, DnaK hydrolyzes its bound ATP, resulting in the formation of a stable complex. GrpE releases ADP from DnaK; ATP binding to DnaK triggers the release of the substrate protein, thus completing the reaction cycle. Several rounds of ATP-dependent interactions betwe [...]

anti-sigma(V) factor; Anti-sigma factor for SigV. Negatively regulates SigV activity through direct interaction.

Copper transporter ATPase; Involved in copper export.
