Flavodoxins are well known one-domain alpha/beta electron-transfer proteins that, according to the presence or absence of a approximately 20-residue loop splitting the fifth beta-strand of the central beta-sheet, have been classified in two groups: long and short-chain flavodoxins, respectively. Although the flavodoxins have been extensively used as models to study electron transfer, ligand bin...
The influence of the amino acid residues sandwiching the flavin ring in flavodoxin (Fld) from the cyanobacterium Anabaena sp. PCC 7119 in complex formation and electron transfer (ET) with its natural partners, photosystem I (PSI) and ferredoxin-NADP(+) reductase (FNR), was examined in mutants of the key residues Trp(57) and Tyr(94). The mutants' ability to form complexes with either FNR or PSI ...
Ferroproteins arose early in Earth's history, prior to the emergence of oxygenic photosynthesis and the subsequent reduction of bioavailable iron. Today, iron availability limits primary productivity in about 30% of the world's oceans. Diatoms, responsible for nearly half of oceanic primary production, have evolved molecular strategies for coping with variable iron concentrations. Our understan...
To investigate the consequences of macromolecular crowding on the behavior of a globular protein, we performed a combined experimental and computational study on the 148-residue singledomain / protein, Desulfovibrio desulfuricans apoflavodoxin. In vitro thermal unfolding experiments, as well as assessment of native and denatured structures, were probed by using far-UV CD in the presence of vari...
