Abstract

In Cyanophora paradoxa, the allophycocyanin apoprotein subunits, α and β, are encoded in the cyanelle (plastid) genome. These genes were transferred to the cyanobacterium Synechococcus sp. PCC 7002 on a plasmid replicon. Phycobilisomes isolated from transformed cyanobacteria were found to contain C. paradoxa allophycocyanin subunits. Thus, these plastid genes are expressed in the cyanobacterium as polypeptides which become linked to a chromophore and are incorporated into the light-harvesting apparatus.
