Significance Cyanobacteria have been increasingly explored as a biotechnological platform, although their economic feasibility relies in part on the capacity to maximize photosynthetic, solar-to-biomass energy conversion efficiency. Here we show that cyanobacterial photosynthetic can be increased by diverting cellular resources toward heterologous, energy-storing metabolic pathways and reducing electron flow photoprotective, but energy-dissipating, oxygen reduction reactions. We further...
Amid growing environmental concerns and the imperative for sustainable agricultural practices, this study examines potential of nitrogen-fixing cyanobacteria as biofertilizers, particularly in cotton cultivation. The reliance on synthetic nitrogen fertilizers (SNFs), prevalent modern agriculture, poses significant challenges, including greenhouse gas emissions water system contamination. This research aims to shift paradigm by exploring capacity a natural alternative. Utilizing advanced...
CyanoCyc is a web portal that integrates an exceptionally rich database collection of information about cyanobacterial genomes with extensive suite bioinformatics tools. It was developed to address the needs research and biotechnology communities. The 277 annotated currently in are supplemented computational inferences including predicted metabolic pathways, operons, protein complexes, orthologs; data imported from external databases, such as features Gene Ontology (GO) terms UniProt. Five...
Abstract Photosynthesis holds the promise of sustainable generation useful products using light energy. Key to realizing this potential is ability rationally design photosynthesis redirect energy and reductant derived from photons desired products. Cytochrome P450s (P450s), which catalyze a broad array reactions, have been engineered into variety photosynthetic organisms, where their activity has shown be photosynthesis-dependent, thus acting as heterologous sinks electrons photosynthesis....
Lutein, made by the α-branch of methyl-erythritol phosphate (MEP) pathway, is one most abundant xanthophylls in plants. It involved structural stabilization light-harvesting complexes, transfer excitation energy to chlorophylls and photoprotection. In contrast, lutein MEP pathway are not present cyanobacteria. this study, we genetically engineered cyanobacterium Synechocystis for missing resulting accumulation. A cassette comprising four Arabidopsis thaliana genes coding two lycopene...
All known photosynthetic cyanobacteria carry a cytochrome c 6 protein that acts transferring electrons from b f complex to photosystem I, in photosynthesis, or oxidase, respiration. In most of the cyanobacteria, at least one homologue is found, so-called 6B 6C . However, function these -like proteins still unknown. Recently, it has been proposed common origin as well reclassification group , renaming new joint 6BC Another not classified yet, formerly called 6-3 which present...
All known cyanobacteria contain Cyt c6, a small soluble electron carrier protein whose main function is to transfer electrons from the b6f complex PSI, although it also involved in respiration. We have previously described second isoform of this protein, c6-like, remains unknown. Here we describe third c6 (here called Cytc6-3), which only found heterocyst-forming filamentous cyanobacteria. c6-3 expressed vegetative cells but specifically repressed heterocysts under diazotrophic growth...
Cytochrome cM was first described in 1994 and its sequence has been found the genome of manifold cyanobacterial species ever since. Numerous studies have carried out with purpose determining function, but none them given place to conclusive results so far. Many these are based on assumption that cytochrome is a soluble protein located thylakoid lumen cyanobacteria. In this work, we reevaluated cM, our showing most probable 3D structure strongly similar C subunit bacterial nitric oxide...
