DNA-catalyzed lysine side chain modification.
Catalyzing the covalent modification of aliphatic amino groups, such as the lysine (Lys) side chain, by nucleic acids has been challenging to achieve. Such catalysis will be valuable, for example, for the practical preparation of Lys-modified proteins. We previously reported the DNA-catalyzed modification of the tyrosine and serine hydroxy side chains, but Lys modification has been elusive. Her...
متن کاملDNA-catalyzed serine side chain reactivity and selectivity.
New deoxyribozymes are shown to catalyze reactions of serine side chains, forming nucleopeptide linkages and discriminating between serine and tyrosine or between two competing serines.
متن کاملDNA-catalyzed covalent modification of amino acid side chains in tethered and free peptide substrates.
This study focuses on the development of DNA catalysts (deoxyribozymes) that modify side chains of peptide substrates, with the long-term goal of achieving DNA-catalyzed covalent protein modification. We recently described several deoxyribozymes that modify tyrosine (Tyr) or serine (Ser) side chains by catalyzing their reaction with 5'-triphosphorylated RNA, forming nucleopeptide linkages. In e...
متن کاملModification of the cysteamine side chain of thienamycin. III.
Thienamycin derivatives (4) having a cyclic amidine moiety at the C-2 position were prepared. The susceptibility to renal dehydropeptidase-1 and the antimicrobial activity of these compounds were determined. Their structure-activity relationships are also discussed.
متن کاملDNA-Catalyzed Introduction of Azide at Tyrosine for Peptide Modification
We show that DNA enzymes (deoxyribozymes) can introduce azide functional groups at tyrosine residues in peptide substrates. Using in vitro selection, we identified deoxyribozymes that transfer the 2'-azido-2'-deoxyadenosine 5'-monophosphoryl group (2'-Az-dAMP) from the analogous 5'-triphosphate (2'-Az-dATP) onto the tyrosine hydroxyl group of a peptide, which is either tethered to a DNA anchor ...
