| K [auth W] | PF04314 | Copper chaperone PCu(A)C domain (PCuAC) | Copper chaperone PCu(A)C domain | PCu(A)C is a periplasmic copper chaperone. Its role may be to capture and transfer copper to two other copper chaperones, PrrC and Cox11, which in turn deliver Cu(I) to cytochrome c oxidase [1]. | Domain |
