In this paper, we present a series of heteronuclear NMR experiments for the direct observation and characterization of lysine NH3 groups in proteins. In the context of the HoxD9 homeodomain bound specifically to DNA we were able to directly observe t

Pyruvate formate-lyase activating enzyme (PFL-AE) is a representative member of an emerging family of enzymes that utilize iron-sulfur clusters and S-adenosylmethionine (AdoMet) to initiate radical catalysis. Although these enzymes have diverse funct

Despite the current availability of several crystal structures of purple acid phosphatases, to date there is no direct evidence for solvent-derived ligands occupying terminal positions in the active enzyme. This is of central importance, because cata

We have characterized, for the first time, motional modes of a protein dissolved in supercooled water: the flipping kinetics of phenylalanyl and tyrosinyl rings of the 6 kDa protein BPTI have been investigated by NMR at temperatures between -3 and -1

We have investigated the lysine side chain amines in the 34 kDa catalytic domain from Cellulomonas fimi beta-(1,4)-glycosidase Cex (or CfXyn10A) using 1H-detected 15N heteronuclear correlation NMR spectroscopy. Signals from the 1Hzeta ( approximately

EDTA-derivatized deoxythymidine (dT-EDTA), incorporated into DNA and complexed to Fe2+ in the presence of dithiothreitol, is a widely used reagent for sequence-specific cleavage of duplex DNA. Using HPLC/electrospray mass spectrometry, we show that c
