A very similar sequence, located ∼60 nucleotides upstream of the atpI initiation codon, was also found in some Chlorophyceae and Ulvale algae species and is essential for atpI mRNA translation in Chlamydomonas. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes. Biosynthesis of ATP by F-type ATP synthases occurs ubiquitously in energy-transducing membranes, providing the main ATP source that drives numerous biochemical reactions in all living cells (Yoshida et al., 2001).In chloroplasts, ATP synthase is located in the thylakoid membrane and comprises two major structural subcomplexes, CF 1 and CF 0 (von Ballmoos et al., 2009; Junge and Nelson, 2015).
