[ATPase subunit 6 gene of Leptomonas seymouri (Trypanosomatidae) is transcribed and edited as a polycistronic
Abstract:
The maturation of mitochondrial RNA transcripts proceeds through several steps. Here we use insects trypanosomatid Leptomonas seymouri as a model organism for analysis of transcription and posttranscriptional processing of mitochondria encoded gene for the subunit 6 of ATPase (A6). It was shown that Cyt b (cytochrome b) and A6 genes were transcribed and edited as a polycistronic template. Analysis of twelve RT-PCR products of both genes led to identification of four types of differently and/or partially edited cDNA molecules. Based on the analysis of two fully edited A6 transcripts we propose the existence of two alternatively edited products.
