Abstract

Certain magic-angle spinning heteronuclear dipolar recoupling experiments using rotor-synchronized pulse trains require very precise control of the sample-spinning rate. An inexpensive spinning speed controller for use in magic-angle solid-state NMR experiments is described which can control the spinning rate to within +/- 0.2 Hz. The apparatus is based on a simple micro-controller and is self-contained. Experimental results are presented that show the importance of good spinning speed control.

Ionic interactions near the loop L4 are important for maintaining the active-site environment and the dimer stability of (pro)caspase 3.

We have examined the role of a salt bridge between Lys242 and Glu246 in loop L4 of procaspase 3 and of mature caspase 3, and we show that the interactions are required for stabilizing the active site. Replacing either of the residues with an alanine residue results in a complete loss of procaspase 3 activity. Although both mutants are active in the context of the mature caspase 3, the mutations result in an increase in K(m) and a decrease in kcat when compared with the wild-type caspase 3. In addition, the mutations result in an increase in the pK(a) value associated with a change in kcat with pH, but does not affect the transition observed for Km versus pH. The mutations also affect the accessibility of the active-site solvent as measured by tryptophan fluorescence emission in the presence of quenching agents and as a function of pH. We show that, as the pH is lowered, the (pro)caspase dissociates, and the mutations increase the pH-dependent instability of the dimer. Overall, the results suggest that the contacts lost in the procaspase as a result of replacing Lys242 and Glu246 are compensated partially in the mature caspase as a result of new contacts that are known to form on zymogen processing

Influence of phenylalanine 120 on cytochrome P450 2D6 catalytic selectivity and regiospecificity: crucial role in 7-methoxy-4-(aminomethyl)-coumarin metabolism.

The polymorphic human debrisoquine hydroxylase, cytochrome P450 2D6 (CYP2D6), is one of the most important phase I drug metabolising enzymes. It is responsible for metabolising a large number of compounds that mostly share similarity in having a basic N-atom and an aromatic moiety. In homology modelling studies, it has been suggested that in fixation of this aromatic moiety, there may be an important role for phenylalanine 120 (Phe(120)). In this study, the role of Phe(120) in ligand binding and catalysis was experimentally examined by mutating it into an alanine. Strikingly, this substitution led to a completely abolished 7-methoxy-4-(aminomethyl)-coumarin (MAMC) O-demethylating activity of CYP2D6. On the other hand, bufuralol metabolism was hardly affected (K(m) of 1-hydroxylation mutant: 1.2 microM, wild-type: 2.9 microM, 4-hydroxylation mutant: 1.5 microM, and wild-type: 3.2 microM) and neither was affected dextromethorphan O-demethylation (K(m) mutant: 1.2 microM, wild-type: 2 microM, k(cat) mutant: 4.5 min(-1), and wild-type: 3.3 min(-1)). However, the Phe(120)Ala mutant also formed 3-hydroxymorphinan, the double demethylated form of dextromethorphan, which was not detected using wild-type CYP2D6. 3,4-Methylenedioxymethamphetamine (MDMA) was demethylenated by both mutant and wild-type CYP2D6 to 3,4-dihydroxymethamphetamine (3,4-OH-MA K(m) of mutant: 55 microM and wild-type: 2 microM). In addition, the mutant formed two additional metabolites; 3,4-methylenedioxyamphetamine (MDA) and N-hydroxy-3,4-methylenedioxymethamphetamine (N-OH-MDMA). Inhibition experiments of dextromethorphan O-demethylation showed a decreased affinity of the Phe(120)Ala mutant for quinidine (IC(50) mutant: 240 nM and wild-type, 40 nM), while IC(50)s for quinine were equal (1 microM). These data indicate the importance of Phe(120) in the selectivity and regiospecificity in substrate binding and catalysis by CYP2D6.

Enzymatic resolution for the preparation of enantiomerically enriched D-beta-heterocyclic alanine derivatives using Escherichia coli aromatic L-amino acid transaminase.

An enzymatic resolution was carried out for the preparation of enriched beta-heterocyclic D-alanine derivatives using Escherichia coli aromatic L-amino acid transaminase. The excess of pyrazole, imidazole, or 1,2,4-triazole reacted with methyl-2-acetamidoacrylate in acetonitrile in the presence of potassium carbonate at 60 degrees C, directly leading to make the potassium salt of the corresponding N-acetyl-beta-heterocyclic alanine derivatives. After the acidic deprotection of the N-acetyl group, 10 mM of racemic pyrazolylalanine, triazolylalanine, and imidazolylalanine were resolved to D-pyrazolylalanine, D-triazolylalanine, and D-imidazolylalanine with 46% (85% ee), 42% (72% ee), and 48% (95% ee) conversion yield in 18 h, respectively, using E. coli aromatic L-amino acid transaminase (EC 2.6.1.5). Although the three beta-heterocyclic L-alanine derivatives have similar molecular structures, they showed different reaction rates and enantioselectivities. The relative reactivities of the transaminase toward the beta-heterocyclic L-alanine derivatives could be explained by the relationship between the substrate binding energy (E, kcal/mol) to the enzyme active site and the distance (delta, A) from the nitrogen of alpha-amino group of the substrates to the C4' carbon of PLP-Lys258 Schiff base. As the ratio of the substrate binding energy (E) to the distance (delta) becomes indicative value of k(cat)/K(M) of the enzyme to the substrate, the relative reactivities of the beta-heterocyclic L-alanine derivatives were successfully correlated with E/delta, and the relationship was confirmed by our experiments.
