arCOG00187 universal archaeal metal-binding-domain/4Fe-4S-binding-domain containing ABC transporter, ATP-binding protein This protein consists of an N-terminal possible metal-binding domain (pfam04068) followed by a 4Fe-4S cluster binding domain (pfam00037) followed by a C-terminal ABC transporter, ATP-binding domain (pfam00005). This combination of N-terminal domains is observed in the RNase L inhibitor, RLI. This model has the same scope as an archaeal COG (arCOG00187) and is found in all completely sequenced archaea and does not recognize any known non-archaeal genes.
