A novel, anaerobically induced ferredoxin in Chlamydomonas reinhardtii
چکیده انگلیسی

We have found the transcript of one of at least six ferredoxin encoding genes of the green alga Chlamydomonas reinhardtii, FDX5, strongly accumulating in anaerobiosis, indicating a vital role of the encoded protein in the anaerobic metabolism of the cells. According to absorption and electron paramagnetic resonance spectroscopy, Fdx5 is a plant-type [2Fe2S]-ferredoxin with a redox potential similar to that of the ferredoxin PetF. However, although Fdx5 seems to be located in the chloroplast, it is not able to photoreduce nicotinamide adenine dinucleotide phosphate (NADP+) via ferredoxin-NADP-reductase, nor to be an electron donor to the plastidic [FeFe]-hydrogenase HydA1. Thus, Fdx5 seems to have a special role in a yet to be identified anaerobic pathway.
