The petFI gene encoding ferredoxin I is located close to the str operon on the cyanelle genome of Cyanophora paradoxa

Abstract: 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-terminal processed methionine) at a position 477 bp from the 3' end of tufA but on the opposite strand. The 25 amino-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 b-type plastids… Show more

“…A similarly pronounced heterogeneity of RNA 5' ends has beca described before in RNase P from yeasts [24,25]. Transcription termination of rnpB likely occurs within a run of uridines contained within a stemloop, a structure frequently described near the end of cyanelle genes and thought to function as a transcription terminator [26,27].…”

“…These include xylene monooxygenase reductase (81), which has 42% identity in 347 amino acid residues; phenol hydroxylase reductases, one of which from P. putida (44) has 35% identity in 336 amino acid residues; and naphthalene dioxygenase reductases, of which the NAH7 plasmid-encoded enzyme (80) has 32% identity in 334 amino acid residues. The ferredoxin of the photosynthetic organelle (cyanelle) of cyanobacterium Cyanophora paradoxa (64) has 34% identity to the amino terminus in 77 amino acid residues.…”

“…a peptidoglucan layer between the envelope membrar es and phy- cobilins instead of Chl b. However, the plastidic character of the cyanoplasts of C. paradoxa is well developed, since many genes of an original endosymbiont have been transferred to the nuclear genome (Bayer and Schenk, 1986;Bayer et al, 1990). In respect to class I and I1 aldolases, a11 cyanobacteria analyzed so far contain only class I1 aldolases and no class I aldolases, as higher plants do (see Ikawa et al, 1972;March and Lebherz, 1992).…”

“…it has a peptidoglucan sacculus and phycobilins ) but lacks Chl b. Furthermore, cyanoplast DNA encodes some proteins that are not encoded by the chloroplast DNA of higher plants: the small subunit of ribulose-1,5-bisphosphate carboxylase (Heinhorst and Shively, 1983), Fd (Bayer and Schenk, 1989;Neumann-Spallart et al, 1990), and a set of ribosomal proteins (Bryant and Stirewalt, 1990; Evrard et al, 1990). On the other hand, the cyanoplasts of C. paradoxa exhibit typical characteristics of higher-plant chloroplasts: a reduced plastome size (Herdman and Stanier, 1977) and the import of nucleus-encoded cyanoplast proteins from the cytosol (Bayer and Schenk, 1986), e.g.…”
