Modified pyrimidines Specifically bind the purine riboswitchModified pyrimidines Specifically bind the purine riboswitch
Structural highlights
Publication Abstract from PubMedThe purine riboswitch is a genetic regulatory element found in the 5'-untranslated regions of Gram-positive bacteria that regulates expression of the mRNA specifically in response to either guanine or adenine. We report that the adenine-responsive RNA element is also capable of specifically recognizing pyrimidine compounds bearing modifications at the 6- or 5,6-positions in a fashion similar to that of purine compounds. Using isothermal titration calorimetry and X-ray crystallography, the binding of these compounds is characterized. Modified pyrimidines specifically bind the purine riboswitch.,Gilbert SD, Mediatore SJ, Batey RT J Am Chem Soc. 2006 Nov 8;128(44):14214-5. PMID:17076468[1] From MEDLINE®/PubMed®, a database of the U.S. National Library of Medicine. See AlsoReferences
