The reactivity of an RNA ribose hydroxyl is shown to be exquisitely sensitive to local nucleotide flexibility because a conformationally constrained adjacent 3'-phosphodiester inhibits formation of the deprotonated, nucleophilic oxyanion form of the 2'-hydroxyl group. Reaction with an appropriate electrophile

LNA (locked nucleic acids, i.e. oligonucleotides with a methyl bridge between the 2' oxygen and 4' carbon of ribose) and 2,6-diaminopurine were incorporated into 2'-O-methyl RNA pentamer and hexamer probes to make a microarray that binds unpaired RNA approximately isoenergetically.

Highly fluorescent N-methylanthranilyl (Mantyl) peptide derivatives were prepared by a one-step reaction with N-methylisatoic anhydride (MIA) for quantitative detection in HPLC. Reactions were carried out in an organic medium of acetonitrile-triethylamine, in aqueous alkaline sodium carbonate and sodium phosphate buffers.

The bacteriophage Mu Com is a small zinc finger protein that binds to its cognate mom mRNA and activates its translation. The Mom protein, in turn, elicits a chemical modification (momification) of the bacteriophage genome, rendering the DNA resistant to

Telomerase is a ribonucleoprotein (RNP) enzyme that requires an integral telomerase RNA (TR) subunit, in addition to the catalytic telomerase reverse transcriptase (TERT), for enzymatic function. The secondary structures of TRs from the three major groups of species, ciliates, fungi
