Abstract

The genes encoding (2Fe-2S) plant-like ferredoxins were studied in the widely-used cyanobacterium Synechocystis PCC6803. The fedl gene (ssl0020) coding for the most abundant ferredoxin product was found to be strongly expressed as a light-induced monocistronic transcript, whereas the other fed genes appeared to be silent (slr1828), or moderately expressed as polycistronic transcripts regulated by either light fluence (slr0150), negative control) or glucose availability (sll1382). fedI was found to be critical to Synechocystis PCC6803 viability in spite of slr0150-, sll1382- or flavodoxin-induction, even after the addition of glucose that compensate for the loss of photosynthesis. Nevertheless, fedI could be deleted from all chromosome copies in cells propagating a fedI gene (even of heterologous origin) on a replicating plasmid. This strain was used as the host for the subsequent introduction of fedI mutant alleles propagated on a second vector. Analysis of the fedI mutant strains generated after plasmid exchange, showed that the C18-C85 disulfide bridge is central neither to the tight compaction of ferredoxin I nor to its reduction by photosystem I, and demonstrate that the length of the FedI carboxy-terminus is important for effective PSI/FedI interactions. The plasmid shuffling strategy presently described has general applicability for mutational analysis of essential genes in many organisms since it is based on promiscuous plasmids.
