ProteomicsIron-starvation induces photosystem I antenna remodeling in green algae
Dunaliella salina and Dunaliella tertiolecta are extremophile, marine algae that can survive in very low Fe conditions. In this study, we used TMT-proteomics to compare the Fe starvation responses to the Fe replete responses. Samples were digested with trypsin, labeled with TMT 10-Plex, then analyze...

ProteomicsIntensity-based absolute quantification (iBAQ) of components of photosystem I monomers and dimers.
Photosystem I (PSI) enables photo-electron transfer and regulates photosynthesis in the bioenergetic membranes of cyanobacteria and chloroplasts. Being a multi-subunit complex, its macromolecular organization affects the dynamics of photosynthetic membranes. Here we reveal a chloroplast PSI from the...

Proteomicsprotein phosphorylation landscape in photosystem I of the desert algae Chlorella sp
The regulation of photosynthesis in response to varying light conditions is primarily controlled through the phosphorylation of thylakoid proteins. This process is most extensively studied in the context of the phosphorylation of photosystem II (PSII) and light-harvesting complex II (LHCII) subunits...

ProteomicsProtein composition of photosystem II supercomplexes from Arabidopsis
The goal of the project is to identify the protein composition (and their relative abundance) of selected photosystem II supercomplexes separated using mild CN-PAGE from thylakoid membranes of Arabidopsis plants lacking proteins i) Lhcb6, ii) Lhcb3, iii) Lhcb3 and Lhcb6. These proteomic data will be...

ProteomicsThe molecular structure of Photosystem I from Chromera velia: A Mehler machine at 1.84 A resolution
Photosystem I is a key component of the solar energy conversion machinery in oxygenic photosynthesis, and its core, where photochemistry occurs, is highly conserved. However, the coral-associated alga Chromera velia, which occupies a unique evolutionary position between photosynthetic algae and para...

ProteomicsThe Antarctic Chlamydomonas spp. UWO241 and ICE-MDV exhibit differential restructuring of Photosystem I in response to iron
Past studies have shown that the photosynthetic apparatus of a psychrophilic alga C. sp. UWO241 is remodeled to support high rates of Photosystem I (PSI)-associated cyclic electron flow (CEF). Iron levels in ELB are in the nanomolar range; therefore, we hypothesized that PSI restructuring in C. sp. ...

ProteomicsOxygenic photosynthesis without photosystem I in a cyanobacterium
Cyanobacteria, algae and plants use oxygenic photosynthesis to fix CO2 and release O2. This process depends on ATP and NADPH, which are produced by the photosynthetic light reactions involving several multi-protein complexes and mobile electron carriers. These complexes include the two photosystems,...

ProteomicsA thylakoid biogenesis BtpA protein is required for the initial step of tetrapyrrole biosynthesis in cyanobacteria
Biogenesis of the photosynthetic apparatus requires complicated molecular machinery, individual components of which are either poorly characterized or unknown. The BtpA protein has been described as a factor required for the stability of Photosystem I (PSI) in cyanobacteria; however, how the BtpA st...
