In cyanobacteria and chloroplasts (in algae plants), ATP synthase plays a pivotal role as photosynthetic membrane complex responsible for producing from adenosine diphosphate inorganic phosphate, utilizing proton motive force gradient induced by photosynthesis. These two synthases exhibit similarities in gene organization, amino acid sequences of subunits, structure, functional mechanisms, suggesting that cyanobacterial is probably the evolutionary precursor to chloroplast synthase. this review, we explore precise synthesis assembly subunits address uneven stoichiometry within during transcription, translation, processes. We also compare regulatory strategies governing activity meet varying energy demands amid fluctuating natural environments.

ATP synthase is a key enzyme in photophosphorylation photosynthesis and oxidative phosphorylation respiration, which can catalyze the synthesis of supply energy to organisms. has been well studied many animal species but poorly characterized plants. This research identified forty family members rubber tree, phylogenetic relationship, gene structure, cis-elements, expression pattern were analyzed. These results indicated that mitochondria was divided into three subgroups chloroplast two subgroups, respectively. same subgroup shared similar structure. Evolutionary relationships consistent with introns exons domains, highly conserved patterns. A large number cis elements related light, phytohormones stress resistance present promoters genes trees, light signal accounts for most. Transcriptome qRT-PCR analysis showed HbATP synthases responded cold hormone stimulation, response ethylene most significant. HbMATPR3 strongly induced by salicylic acid, reaching 122-fold 17-fold, HbMATP7-1 41 times higher than control after induction jasmonic acid. laid foundation further studies on function synthase, especially plant signaling trees.

F-type ATP synthase (F 1 F O ) catalyzes proton motive force-driven synthesis in mitochondria, chloroplasts, and bacteria. Different from the mitochondrial bacterial enzymes, photosynthetic organisms have evolved diverse structural mechanistic details to adapt light-dependent reactions. Although complete structure of chloroplast has been reported, no high-resolution an bacteria available. Here, we report cryo-EM structures intact functionally competent Chloroflexus aurantiacus ( Ca ), a filamentous anoxygenic phototrophic bacterium earliest branch organisms. The its ADP-free ADP-bound forms for three rotational states reveal previously unrecognized architecture synthases. A pair peripheral stalks connect head through dimer δ-subunits, associate with two membrane-embedded a-subunits that are asymmetrically positioned outside clamp ’s c 10 -ring. constitute inlets on periplasmic side outlets cytoplasmic side, endowing unique translocation pathways allow more protons being translocated relative single a-subunit . Our findings deepen understanding mechanisms synthases suggest innovative strategies modulating their activities by altering number a-subunit.
