The downstream atpE cistron is efficiently translated via its own cis-element in partially overlapping atpB–atpE dicistronic mRNAs in chloroplasts
The chloroplast atpB and atpE genes encode subunits β and ε of the ATP synthase, respectively. They are co-transcribed as dicistronic mRNAs in flowering plants. An unusual feature is an overlap (AUGA) of the atpB stop codon (UGA) with the atpE start codon (AUG). Hence, atpE translation has been believed to depend on atpB translation (i.e. translational coupling). Using an in vitro translation s...
متن کاملEvidence for Nuclear Control of the Expression of the atpA and atpB Chloroplast Genes in Chlamydomonas.
We analyzed three nuclear mutants of Chlamydomonas reinhardtii altered in the expression of the chloroplast genes atpA or atpB coding for the [alpha] or [beta] subunit of the chloroplast ATP synthase. These mutants revealed the existence of three nuclear products controlling the expression of the two chloroplast genes: the first one acts on the translation of the atpA transcript, and the two ot...
متن کاملA nuclear gene in maize required for the translation of the chloroplast atpB/E mRNA.
To elucidate mechanisms that regulate chloroplast translation in land plants, we sought nuclear mutations in maize that disrupt the translation of subsets of chloroplast mRNAs. Evidence is presented for a nuclear gene whose function is required for the translation of the chloroplast atpB/E mRNA. A mutation in atp1 results in a failure to accumulate the chloroplast ATP synthase complex due to re...
متن کاملEnhancement of translational efficiency by the Escherichia coli atpE translational initiation region: its fusion with two human genes.
The cDNA sequences encoding mature human interleukin 2 (IL2) and beta-interferon (INF beta), respectively, were fused with various translational initiation regions and inserted into two different types of expression vector. The relative levels of expression of the two genes and the functional stability of their respective mRNAs were examined in vivo in Escherichia coli hosts. The addition of th...

در دوره های آموزش ترجمه استادان بیشتر سعی دارند دانشجویان را با انواع متون آشنا سازند، درحالی که کمتر به خطاهای مکرر آنان در متن ترجمه شده می پردازند. اهمیت تحقیق حاضر مبنی بر ارتکاب مکرر خطاهای ترجمانی حتی بعد از گذراندن دوره های تخصصی ترجمه از سوی دانشجویان است. هدف از آن تاکید بر خطاهای رایج میان دانشجویان مترجمی و کاهش این خطاها با افزایش آگاهی و هوشیاری دانشجویان از بروز آنها است.از آنجا ک...
