Essential Cys-Pro-Cys motif of Caenorhabditis elegans copper transport ATPase.
Caenorhabditis elegans putative copper ATPase (CUA-1) had been functionally expressed in a yeast delta ccc2 mutant (copper ATPase gene disruptant). We found that CUA-1 with Cys-Pro-Cys to Cys-Pro-Ala mutation could not rescue the yeast delta ccc2 mutant, suggesting that the carboxyl terminal cysteine residue in the conserved Cys-Pro-Cys motif is essential for copper transport.
