Abstract

In magic angle spinning solid state NMR experiments the potential of heteronuclear (1)H decoupling employing a continuous train of adiabatic inversion pulses has been assessed via numerical simulations and experimental measurements. It is shown that, with a (1)H RF field strength of approximately 100 kHz that is typically available in MAS NMR probes, it is possible to achieve efficient adiabatic (1)H decoupling at low magic angle spinning frequencies. It is pointed out that in the presence of H (1) inhomogeneities it will be advantageous to employ adiabatic decoupling in MAS solid state NMR experiments.

Can the replacement of a single atom in the enzyme horseradish peroxidase convert it into a monoxygenase? A density functional study.

Density functional calculations on horseradish peroxidase mutants are presented, whereby one or two of the nitrogen atoms of the axial histidine ligand have been replaced by phosphorus atoms. Our calculations show that phosphorus entices a push effect on the oxoiron group, whereas a histidine side chain withdraws electrons. As a result, we predict that a phosphorus-substituted histidine ligand will convert the active form of a peroxidase into a monoxygenase. This subsitution may be useful for the bioengineering of commercially exploitable enzymes.

Modifications of the pyroglutamic acid and histidine residues in thyrotropin-releasing hormone (TRH) yield analogs with selectivity for TRH receptor type 2 over type 1.

Thyrotropin-releasing hormone (TRH) analogs in which the N-1(tau) or the C-2 position of the imidazole ring of the histidine residue is substituted with various alkyl groups and the l-pyroglutamic acid (pGlu) is replaced with the l-pyro-2-aminoadipic acid (pAad) or (R)- and (S)-3-oxocyclopentane-1-carboxylic acid (Ocp) were synthesized and studied as agonists for TRH receptor subtype 1 (TRH-R1) and subtype 2 (TRH-R2). We observed that several analogs were selective agonists of TRH-R2 showing relatively less or no activation of TRH-R1. For example, the most selective agonist of the series 13, in which pGlu is replaced with the pAad and histidine residue is substituted at the N-1 position with an isopropyl group, was found to activate TRH-R2 with a potency (EC(50)=1.9microM) but did not activate TRH-R1 (potency>100 microM); that is, exhibited >51-fold greater selectivity for TRH-R2 versus TRH-R1. Analog 8, in which pGlu is replaced with pAad and histidine is substituted at the N-1(tau) position with a methyl group, exhibited a binding affinity (K(i)=0.0032 microM) to TRH-R1 that is similar to that of [Ntau(1)-Me-His]-TRH and displayed potent activation of TRH-R1 and TRH-R2 (EC(50)=0.0049 and 0.0024 microM, respectively). None of the analogs in which pGlu is replaced with the bioisosteric (R)- and (S)-(Ocp) and the imidazole ring is substituted at the N-1(tau) or C-2 position were found to bind or activate either TRH-R1 or TRH-R2 at the highest test dose of 100 microM.

Ni/NiO core/shell nanoparticles for selective binding and magnetic separation of histidine-tagged proteins.

Ni/NiO core/shell nanoparticles having high affinity with polyhistidine were synthesized by decomposition of a Ni surfactant complex followed by air oxidation. Ni/NiO nanoparticles showed selective and efficient binding to histidine-tagged proteins and easy separation by using a magnet. These provided a more convenient way to efficient purification of histidine-tagged proteins compared with the conventional Ni-NTA complex-bound resins and microbeads.
