Micronutrients are involved in all metabolic and cellular functions. Plants differ in their need
for micronutrients, and we will focus here only on those elements that are generally …

Reversible redox post-translational modifications such as oxido-reduction of disulfide bonds,
S-nitrosylation, and S-glutathionylation, play a prominent role in the regulation of cell …

Cadmium (Cd) is a widely distributed soil contaminant which induces oxidative damage and
is therefore toxic to plants. Although selenium oxyanions such as selenite (SeO 3 2-) and …

Photosynthetic complex I enables cyclic electron flow around photosystem I, a regulatory
mechanism for photosynthetic energy conversion. We report a 3.3-angstrom-resolution cryo …

In methanogenic archaea, the carbon dioxide (CO2) fixation and methane-forming steps are
linked through the heterodisulfide reductase (HdrABC)–[NiFe]-hydrogenase (MvhAGD) …

Ferredoxin (Fd) is a small [2Fe‐2S] cluster‐containing protein found in all organisms
performing oxygenic photosynthesis. Fd is the first soluble acceptor of electrons on the …

Cyclic electron flow around photosystem I (PSI) is a mechanism by which photosynthetic
organisms balance the levels of ATP and NADPH necessary for efficient photosynthesis …

Forty years ago, ferredoxin (Fdx) was shown to activate fructose 1, 6-bisphosphatase in
illuminated chloroplast preparations, thereby laying the foundation for the field now known …

Thioredoxins (Trxs) are low-molecular-weight proteins that participate in the reduction of
target enzymes. Trxs contain a redox-active disulfide bond, in the form of a WCGPC amino …

An inventory of unique local protein folds around Fe–S clusters has been derived from the
analysis of protein structure databases. Nearly 50 such folds have been identified, and over …
