Abstract

The unicellular green alga Chlamydomonas reinhardtii is used extensively as a model to study eukaryotic photosynthesis, flagellar functions, and more recently the production of hydrogen as biofuel. Two of these processes, photosynthesis and hydrogen production, are highly dependent on iron–sulfur (Fe–S) enzymes. To understand how Fe–S proteins are assembled in Chlamydomonas, we have analyzed its recently sequenced genome for orthologs of genes involved in Fe–S cluster assembly. We found a total of 32 open reading frames, most single copies, that are thought to constitute a mitochondrial assembly pathway, mitochondrial export machinery, a cytosolic assembly pathway, and components for Fe–S cluster assembly in the chloroplast. The chloroplast proteins are also expected to play a role in the assembly of the H-cluster in [FeFe]-hydrogenases, together with the recently identified HydEF and HydG proteins. Comparison with the higher plant model Arabidopsis indicated a strong degree of conservation of Fe–S cofactor assembly pathways in the green lineage, the pathways being derived from different origins during the evolution of the photosynthetic eukaryote. As a haploid, unicellular organism with available forward and reverse genetic tools, Chlamydomonas provides an excellent model system to study Fe–S cluster assembly and its regulation in photosynthetic eukaryotes.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
