摘要
The petFI gene encoding ferredoxin I was localized in the large single copy region of cyanelle DNA by heterologous hybridization. Sequence analysis revealed an ORF of 99 amino acids (including the N-tenninal processed methionine) at a position 477 bp from the 3' end of tufA but on the opposite strand. The 25 ammo-terminal residues well corresponded to partial sequences obtained with purified cyanelle ferredoxin. The assignment of yet another gene that is not found on the genomes of chlorophyll β-type plastids to cyanelle DNA again corroborates the special position of cyanelles serving as a model for plastid evolution from endocytobiotic cyanobacteria. © 1990.
