Evidence for nucleotide-dependent processes in the thylakoid lumen of plant chloroplasts - an update

► We review the evidence for nucleotide-dependent reactions in the thylakoid lumen. ► The proteins involved contain non-canonical functional domains. ► Thylakoid membrane harbors one ATP/ADP carrier and one Pi transporter. ► We model a role of these components in photosystem II repair. ► This mechanism may be restricted to plants.
