An mRNA 3' processing site targets downstream sequences for rapid degradation in Chlamydomonas chloroplasts.
In Chlamydomonas chloroplasts, atpB pre-mRNA matures through a two-step process. Initially, endonuclease cleavage occurs 8-10 nt downstream of the mature 3' end, which itself lies at the end of a stem-loop-forming inverted repeat (IR) sequence. This intermediate product is then trimmed by a 3' -->5' exonuclease activity. Although the initial endonucleolytic cleavage by definition generates two ...
متن کاملAntisense transcript and RNA processing alterations suppress instability of polyadenylated mRNA in chlamydomonas chloroplasts.
In chloroplasts, the control of mRNA stability is of critical importance for proper regulation of gene expression. The Chlamydomonas reinhardtii strain Delta26pAtE is engineered such that the atpB mRNA terminates with an mRNA destabilizing polyadenylate tract, resulting in this strain being unable to conduct photosynthesis. A collection of photosynthetic revertants was obtained from Delta26pAtE...
متن کاملSn-Glycerol-3-phosphate is a Product of Starch Degradation in Isolated Chloroplasts from Chlamydomonas reinhardii
Sn-glycerol-3-phosphate accumulates during starch catabolism by intact isolated chloroplasts from Chlam ydom onas reinhardii in the dark. Further products detected mainly were 3-phosphoglyceric acid and triose phosphates with a ratio between 3-phosphoglyceric acid, sn-glycerol-3phosphate and triose phosphates of 1 .0 :0 .9 :0 .2 . The production of sn-glycerol-3-phosphate by a plastidic glycero...
متن کاملA Massively Parallel Reporter Assay of 3' UTR Sequences Identifies In Vivo Rules for mRNA Degradation.
The stability of mRNAs is regulated by signals within their sequences, but a systematic and predictive understanding of the underlying sequence rules remains elusive. Here we introduce UTR-seq, a combination of massively parallel reporter assays and regression models, to survey the dynamics of tens of thousands of 3' UTR sequences during early zebrafish embryogenesis. UTR-seq revealed two tempo...
متن کاملProcessing endoribonucleases and mRNA degradation in bacteria.
Forty years have passed since the dramatic identification of mRNA, the unstable carrier of genetic information from DNA to protein (15, 48, 56). During the last decade, there have been scores of papers and reviews that assume that RNase E is the central enzyme for degradation of mRNA. (There have been hundreds of papers and many reviews on RNase E and mRNA degradation, with at least 60 just in ...
