The Ycf46 mutant of
Synechocystis
showed growth inhibition under low dissolved CO
2
conditions, suggesting a role for the Ycf46 protein in the process of photosynthetic CO
2
uptake and utilization.
Hypothetical chloroplast open reading frame Ycf46 proteins are highly conserved in all cyanobacterial lineages and most algal chloroplast genomes, but their exact function is still unknown. In the cyanobacterium Synechocystis sp. PCC 6803, the Ycf46 encoding gene slr0374 is part of an operon (with slr0373 and slr0376) and responds to many environmental stresses. Transcript levels of t...
