This domain is found in CorA present in Methylomicrobium album. CorA is a copper repressible surface associated copper(I)-binding protein. CorA can bind one copper ion per protein molecule. The overall fold of CorA is similar to M. capsulatus protein MopE, including the unique copper(I)-binding site and most of the secondary structure elements [1].
