Comment | This model represents a family of proteobacterial TonB-dependent outer membrane receptor/transporters which bind and translocate copper ions. Two characterized members of this family exist, outer membrane protein C (OprC) from Pseudomonas aeruginosa [1] and NosA from Pseudomonas stutzeri which is responsible for providing copper for the copper-containing N2O reducatse [2]. |
