  Regiospecificity of the Peptidyl tRNA Ester within the Ribosomal P Site

  摘要：

  The ribosomal peptidyl transferase center is expected to be regiospecific with regard to its tRNA substrates, yet the ester linkages between the tRNA and the amino acid or peptide are susceptible to isomerization between the O2' and O3' hydroxyls of the terminal A76 ribose sugar. To establish which isomer of the P site tRNA ester is utilized by the ribosome, we prepared two nonisomerizable transition state inhibitors with either an A76 O2' or O3' linkage. Strong preferential binding to the O3' regioisomer indicates that the peptidyl transferase proceeds through a transition state with an O3'-linked peptide in the P-site.

• Serendipitous Discovery of α-Hydroxyalkyl Esters as β-Lactamase Substrates

  O-(1-Carboxy-1-alkyloxycarbonyl) hydroxamates were found to spontaneously decarboxylate in aqueous neutral buffer to form O-(2-hydroxyalkylcarbonyl) hydroxamates, While the former molecules do not react rapidly with serine beta-lactamases, the latter are quite good substrates of representative class A and C, but not D, enzymes, and particularly of a class C enzyme. The enzymes catalyze hydrolysis of these compounds to a mixture of the alpha-hydroxy acid and hydroxamate. Analogous compounds containing aryloxy leaving groups rather that hydroxamates are also substrates. Structure-activity experiments showed that the alpha-hydroxyl group was required for any substantial substrate activity. Although both D- and L-alpha-hydroxy acid derivatives were substrates, the former were preferred. The response of the class C activity to pH and to alternative nucleophiles (methanol and D-phenylalanine) suggested that the same active site functional groups participated in catalysis as for classical substrates. Molecular modeling was employed to explore how the alpha-hydroxy group might interact with the class C beta-lactamase active site. Incorporation of the alpha-hydroxyalkyl moiety into novel inhibitors will be of considerable interest.
• Transition State Analogy of Phosphonic Acid Peptide Inhibitors of Pepsin

  A series of 11 phosphonate peptide analogs, RO(2)C-Xaa-Yaa-Phe-(PO2--O)-Phe O-(3-(4-pyridyl)propyl ester), were synthesized and evaluated as inhibitors of the aspartic peptidase pepsin. For the inhibitors with Gly or Ala at the P-2 position, the K-i values correlate with the K-m/k(cat) values of the corresponding substrates, demonstrating that these analogs mimic the transition state in the way the P-2-P-4 residues bind. Deviations from the correlation for the other inhibitor/substrate pairs imply a different binding orientation as a result of N-substitution at P-2 (Pro), contamination with the more potent diastereomer (D-Ala), or a change in rate-limiting step for turnover (lie).
