FunFam 20: ABC metal ion transporter

There are 2 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
ABC-type glutathione-S-conjugate transporter. [EC: 7.6.2.3]
ATP + H(2)O + glutathione-S-conjugate(Side 1) = ADP + phosphate + glutathione-S-conjugate(Side 2).
  • A eukaryotic ATP-binding cassette (ABC) type transporter that mediates the transport of glutathione-S-conjugates.
  • The mammalian enzyme, which also transports some glucuronides, exports the substrates out of the cell, while plant and fungal transporters export them into the vacuole.
  • Over-expression confers resistance to anticancer drugs by their efficient exportation in glutathione-S-conjugate form.
1 P39109
ABC-type Cd(2+) transporter. [EC: 7.2.2.2]
ATP + H(2)O + Cd(2+)(Side 1) = ADP + phosphate + Cd(2+)(Side 2).
  • A Saccharomyces cerevisiae enzyme that exports some heavy metals, especially Cd(2+), from the cytosol into the vacuole.
  • Formerly EC 3.6.3.46.
