Sulfide inhibits oxygenic photosynthesis by blocking electron transfer between HO and the oxygen-evolving complex in the D1 protein of Photosystem II. The ability of cyanobacteria to counter this effect has implications for understanding the productivity of benthic microbial mats in sulfidic environ...
