Prokaryotes also Protect their RNAs – New Types of 5' RNA Caps
Keywords:
5'-RNA cap, NAD-RNA, RNA chemical modificationAbstract
It was long time pressumed that only eukaryotes protect their RNA by 5'-RNA cap. Recently, it was shown that also prokaryotes employ some kind of protection of their RNA in the form of 5'-triphosphate or NAD covalently attached to 5'-terminus. This review discusses the state of art of 5'-RNA cap in eukaryotes and prokaryotes.
