Abstract excerpt
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 is similar to that...
