“…Moreover, the 3 H/ 32 P ratio was the same in UMP and CMP. indicating that deamination of cytidine into uridine plays a key role in RNA editing in plant mitochondria (Blanc et al, 1995). These results are in good agreement with the in organello experiments described previously which showed that the α-phosphate is retained during C-to-U conversion in plant mitochondrial RNAs (Rajasekhar et al, 1993).…”

“…Unfortunately, they were not suitable to study the enzymatic mechanism involved in this reaction. Thus, we settled a simplified in vitro system for routine assays which uses an in vitro radioactively labelled atp9 mRNA as substrate (Blanc et al, 1995;Blanc et al, 1996). After incubation with the mitochondrial lysate the edited product was extensively digested with nuclease P1 and submitted to a double dimension thin-layer chromatography (TLC) to separate the 5' NMPs.…”

“…Initial in vitro experiments from plant mitochondria had indicated that the sugar phosphate backbone remains intact during the deamination step of C to U editing (6,(15)(16)(17). Analogous observations with the in vitro systems for tobacco and pea chloroplasts further support the similarity between the editing processes in both organelles (8,9).…”

“…Data indicate that C-to-U edits occur by base modification rather than by base or nucleotide replacement (19)(20)(21), pointing to a cytidine deaminase as the responsible activity (the available evidence does not, however, exclude a transaminase activity, which could theoretically account for both C-to-U and U-to-C edits). Reproducible mitochondrial or chloroplast extracts capable of supporting efficient editing in vitro have proven very difficult to generate, so that analysis of the mechanism of C-to-U editing has to date been limited, with no biochemical investigation at all being reported in the case of U-to-C editing.…”
