Applying Crystallography and 19 F NMR to investigate dynamics and partner protein interactions in a long chain Flavodoxin
Flavodoxin (Fld) is a small FMN containing protein that is involved in single electron transfer. The long-chain flavodoxin in Rhodopseudomonas palustris bacteria replaces ferredoxin as a low-potential electron carrier when iron is scarce. Thus it is proposed to interact with the bifurcating electron transfer flavoprotein (ETF) that yields low-potential electrons. A surface loop on Fld interacts with another of Fld's partner proteins, so we hypothesize that it also mediates Fld's interaction with...
