Role of hydrophobic interactions in the flavodoxin mediated electron transfer from photosystem I to ferredoxin-NADP+ reductase in Anabaena PCC 7119.

Hydrophobic interactions play an active role in effective complex formation between ferredoxin-NADP(+) reductase (FNR) and ferredoxin (Fd) from Anabaena, where an aromatic amino acid residue on the Fd surface (F65) and three hydrophobic residues (L76, L78, and V136) on the reductase surface have been shown to be essential for the efficient electron transfer (ET) reaction between Fd and FNR (Martínez-Júlvez et al.
