A MerR family metalloregulatory protein CupR selectively responds to gold stress in Ralstonia metallidurans. A distorted trigonal geometry appears to be used by CupR to achieve the highly sensitive (K(d) approximately 10(-35) M) and selective recogni

NMR-based drug screening methods provide the most reliable characterization of binding propensities of ligands to their target proteins. Unique to NMR is its capability to detect weak microM-mM bindings. NMR assays are, however, one of the least effe

We previously used a combination of CW and pulsed-ENDOR protocols to identify the types of protonated oxygen (OHx) species and their disposition within the FeIII/FeIV cluster of Intermediate X, the direct precursor of the essential diferric-tyrosyl r

The Escherichia coli ribonucleotide reductase (RNR) catalyzes the conversion of nucleoside diphosphates to deoxynucleotides and requires a diferric-tyrosyl radical cofactor for catalysis. RNR is composed of a 1:1 complex of two homodimeric subunits:

This study shows that the role of DNA in the DNA-based enantioselective Diels-Alder reaction of azachalcone with cyclopentadiene is not limited to that of a chiral scaffold. DNA in combination with the copper complex of 4,4'-dimethyl-2,2'-bipyridine

A molecular dynamics (MD) simulation was performed on the hydrated decapeptide Ala 10 .550H 2 O under periodic boundary conditions. The initial configuration of the peptide was a canonical right-handed α-helix. Over the course of the MD trajectory,

It was recently suggested that partially reduced monoamine oxidase (MAO) A contains an equilibrium mixture of an anionic flavin radical and a tyrosyl radical (Rigby, S. E.; et al. J. Biol. Chem. 2005, 280, 4627-4632). These observations formed the ba
