| Type: | Family | Name: | Cobalt/zinc/cadmium resistance protein CzcB |
| Description: | Gram-negative bacteria have evolved transport complexes that export macromolecules and toxic substances such as heavy metals across the two membranes of the cell envelope in a single energy coupled step. The process requires (1) a cytoplasmic membrane export system, (2) a membrane fusion protein (MFP), and (3) an outer membrane factor. Phylogenetic analyses reveal that the MFPs cluster in accordance with the type of cytoplasmic membrane transport systems with which they function - proteins in this family are associated with reisistance to heavy metal poisoning. | Short Name: | Co/Zn/Cd_resistance_CzcB |
