1.A.56.1.11
Vacuolar/tonoplast copper transporter 5 (AtCOPT5).  It exports copper from the vacuole to the cytoplasm and is required for photosynthetic electron transport under comditions of copper deficiency.  It also promotes interorgan allocation of copper (Garcia-Molina et al. 2011; Klaumann et al. 2011Klaumann et al. 2011).
