Two Menkes-type atpases supply copper for photosynthesis in Synechocystis PCC 6803.

The Journal of biological chemistry - 8 Jun 2001

Tottey S, Rich P R, Rondet S A, Robinson N J

Abstract excerpt

Synechocystis PCC 6803 contains four genes encoding polypeptides with sequence features of CPx-type ATPases, two of which are now designated pacS and ctaA. We show that CtaA and PacS (but not the related transporters, ZiaA or CoaT) facilitate switching to the use of copper (in plastocyanin) as an alternative to iron (in cytochrome c(6)) for the carriage of electrons within the thylakoid lumen. Disruption of pacS...
