mtrH
mtrH is a gene encoding a multiheme c-type cytochrome associated with extracellular electron transfer in metal-reducing bacteria, most notably within Shewanella species. It is typically found in or near the mtr operon, which also includes mtrA, mtrB, and mtrC, though the exact arrangement and presence of mtrH can vary among strains.
Proteins encoded by mtrH are predicted to contain multiple heme-binding motifs (CXXCH), characteristic of c-type cytochromes,
Functionally, mtrH is considered to participate in the transfer of electrons from the inner membrane to outer
Understanding mtrH contributes to broader insights into extracellular electron transfer, biogeochemical cycling of metals, and potential
mtrH was identified through genome sequencing and comparative genomics of Shewanella and related bacteria and has
