Probable cytochrome c biosynthesis protein, plants (IPR003569)

Short name: Cyt_c_biogenesis_plant

Overlapping homologous superfamilies


Family relationships


Analysis of a transcribed region in the mitochondrial genome from members of the genus Oenothera, revealed an open reading frame (ORF) that is also conserved in Daucus carota (Carrot) [PMID: 8389979]. Extensive RNA editing (46 C to U transitions) alters the Oenothera bertiana mRNA sequence, yielding a sequence with high similarity to the homologous gene product in Marchantia polymorpha (Liverwort). The deduced polypeptides share significant similarity with the ccl1-encoded protein involved in cytochrome c biogenesis in the photosynthetic bacterium Rhodobacter capsulatus. A highly conserved domain is also found in plastid ORFs, suggesting that these bacterial, chloroplast and mitochondrial genes encode polypeptides with analogous functions in assembly and maturation of cytochromes c [PMID: 8389979].
