Abstract:
:Sequence comparisons of 5 S and other ribosomal RNAs by segments can be useful in understanding anomalous primary and secondary structures and in assessing phylogenetic relationships. In a segmented analysis, the 5'-half of the Chlamydomonas reinhardii chloroplast 5 S ribosomal RNA is found to have a very close sequence homology to the green plant chloroplast and cyanobacterial 5 S RNAs; however, the 3'-half has a highly unusual sequence. Further comparisons of homologies between regions of the 5 S RNAs from C. reinhardii and the green plant chloroplasts suggest that genetic rearrangements within the 5 S DNA may have produced the unusual sequence at the 3'-half. Segmented analyses of the C. reinhardii and green plant chloroplast 5 S RNAs suggest a close relationship which is not revealed by overall sequence comparisons.

FEBS LETTERS文献大全abstract::Human Bfl-1 is an anti-apoptotic Bcl-2 family member. Here, we found that Bfl-1 was converted into a potent death-promoting protein by green fluorescent protein (GFP) fusion with its N-terminus. The transient expression of GFP-Bfl-1 induced cytochrome c release and triggered apoptosis in 293T cells, which depended on ...
