Sequence length | 560 AA |
Subcellular Location | Periplasm |
Function | A high molecular mass cytochrome that harbours 16 c-type heme groups. Involved in electron transfer from the periplasm to the cytoplasm. The high molecular mass complex Hmc (HmcA–HmcF) from Desulfovibrio sp. has been proposed to be involved in the bridge between periplasmic hydrogen oxidation and cytoplasmic sulphate reduction in Desulfovibrio gigas. |

Protein Glycosylation- Implication | Carbohydrate could be acting as an anchor of the protein to the phospholipidic membrane. The carbohydrate bound to HmcA may also contribute to the maintenance of the protein conformation and stability as well as to a protection mechanism against proteases. |
