Fig. 5From: Customized exogenous ferredoxin functions as an efficient electron carrierAnalysis of the proposed electron transfer pathway between oxidoreductase and free Fdx. The overall structures of reductase PRF, free ferredoxin DmFdx2 and oxygenase KshA are shown as surface representation. NADH and FMN are shown as sticks, iron atoms and [2Fe–2S] cluster groups are shown as spheresBack to article page
