Inactivation of the petE gene for plastocyanin lowers photosynthetic capacity and exacerbates chilling-induced photoinhibition in the cyanobacterium Synechococcus

We describe the identification and expression of a petE gene in Synechococcus sp. PCC 7942, a cyanobacterium previously thought to lack plastocyanin. The petE gene is a 420-bp open reading frame that encodes a protein 70 to 75% similar to plastocyanins from other cyanobacteria. Synechococcus possess...
