Sequence‐Specific DNA Recognition with Designed Peptides
(Wiley, 2018)
Inspired by natural transcription factors (TFs), researchers have explored the potential of artificial peptides for the recognition of specific DNA sequences, developing increasingly sophisticated systems that not only ...
Stereoselective Formation of Chiral Metallopeptides
(Wiley, 2012-05-03)
Playing into our hands: The achiral bipyridine amino acid fluorenylmethyloxycarbonyl 5‐amino‐3‐oxapentanoic acid (Fmoc‐O1PenBpy‐OH) has been used for the solid‐phase synthesis of metallopeptides. Circular dichroism, molecular ...
Recruitment of RNA molecules by connexin RNA-binding motifs: Implication in RNA and DNA transport through microvesicles and exosomes
(Elsevier, 2017-04)
Connexins (Cxs) are integral membrane proteins that form high-conductance plasma membrane channels, allowing communication from cell to cell (via gap junctions) and from cells to the extracellular environment (via ...
Temporary Electrostatic Impairment of DNA Recognition: Light‐Driven DNA Binding of Peptide Dimers
(Wiley, 2012)
Appending negatively charged Glu8 tails to a peptide dimer derived from the GCN4 transcription factor leads to an effective suppression of its DNA binding. The specific DNA recognition can be restored by irradiation with ...
Straightforward access to bisbenzamidine DNA binders and their use as versatile adaptors for DNA-promoted processes
(Royal Society of Chemistry, 2012)
Bisbenzamidines are an important family of minor groove DNA-binding agents. We present a one-step synthesis of aromatic aza-bisbenzamidines that allows straightforward and versatile access to a large number of these ...
Single‐Molecule Approach to DNA Minor‐Groove Association Dynamics
(Wiley, 2012)
Getting in the groove: Fluorescence correlation spectroscopy reveals that the dynamics of the association process of the bisbenzamidine minor‐groove binder BBA‐OG (blue with green star, see scheme) to dsDNA is not controlled ...
Sequence‐Selective DNA Recognition with Peptide–Bisbenzamidine Conjugates
(Wiley, 2013)
Transcription factors (TFs) are specialized proteins that play a key role in the regulation of genetic expression. Their mechanism of action involves the interaction with specific DNA sequences, which usually takes place ...
MitoBlue: A Nontoxic and Photostable Blue-Emitting Dye That Selectively Labels Functional Mitochondria
(American Chemical Society, 2014)
We report the discovery of a fluorogenic dye, N1,N3-di(2-aminidonaphthalen-6-yl) propane-1,3-diamine, MitoBlue, which selectively stains functional mitochondria while displaying low toxicity, bright blue emission, and high ...
Selective G-quadruplex binding by oligoarginine-Ru(dppz) metallopeptides
(Royal Society of Chemistry, 2018)
A set of Ru(II) metallopeptides containing the dppz ligand has been synthesized using SPPS methods. Fluorescence titration studies show that those metallopeptides featuring an octaarginine tail display a large binding ...
Programmed stereoselective assembly of DNA-binding helical metallopeptides
(Royal Society of Chemistry, 2014)
A flexible and versatile synthetic approach for the construction of water-stable DNA-binding chiral peptide helicates based on the solid phase peptide synthesis (SPPS) methodology is reported
