Overview

The ferredoxin gene which makes up this part is found in the ferredoxin reductase operon in the hydrogen production pathway of our project. Ferredoxin is the last electron acceptor thus reducing the enzyme NADP+ reductase.

Biology & Literature

Ferredoxin-NADP reductase (FNR) has a mass of 36kDa and shows ferredoxin-dependent cytochrome c reduction activity [1]. This enzyme facilitates electron transfer from ferredoxin to NADP [2]. In vivo studies showed that this protein is N-trimethylated on 3 different lysines – K135, K83 and K89). This modification is thought to be involved in regulation and structural modulation since the methylated protein is smaller and more compact. Studies comparing FNR protein from Chlamydomonas reinhardtii with recombinant protein expressed in E. coli showed that the latter had a higher Km value for NADPH [3].
PETF plays a role in transfer of electrons between photosystem I and FNR [4]. It has been shown to enhance heat stress tolerance when it is overexpressed in Chlamydomonas reinhardtii by downregulating the levels of reactive oxygen species.
