Homology of the N-terminal domain of the petH gene product from Anabaena sp. PCC 7119 to the CpcD phycobilisome linker polypeptide

Abstract
The complete nucleotide sequence of the petH gene encoding ferredoxin-NADP+ reductase from the nitrogen-fixing cyanobacterium Anabaena sp. PCC 7119 has been determined. The encoded polypeptide is 136 amino acids longer than the enzyme obtained after purification to homogeneity. The extended N-terminal domain consists of 80 amino acids which shows homology to the CpcD phycobilisome linker polypeptide, through which FNR might be anchored to the thylakoid-bound phycobilisomes. A 56 amino acid interdomain fragment is found which could be a target for proteolysis.
