  Chemistry and Photochemistry Attending the Inactivation of Escherichia coli .beta.-Hydroxydecanoyl Thiol Ester Dehydrase by an Acetylenic Diazoketone

  摘要：

  beta-Hydroxydecanoyl thiol ester dehydrase from Escherichia coli, an enzyme that catalyzes both dehydration and allylic rearrangement reactions, has been shown previously to undergo mechanism-based inactivation by the acetylenic substrate analog 1-diazo-4-undecyn-2-one (DUO). Details of the chemistry and photochemistry of DUO are now presented. Analysis of DUO-inactivated dehydrase by N-15 NMR spectroscopy indicates that DUO quantitatively alkylates histidine-70. Long-wavelength photoirradiation leads to spectrophotometrically observable changes in the DUO-dehydrase adduct. The structural changes were characterized by a combination of methods. Samples of protein that had been inactivated with [1-C-13]-, [(2)-C-13]-, and [3-C-13]DUO were analyzed by C-13 NMR spectroscopy, both prior and subsequent to photoirradiation. By comparisons of the chemical shifts of the enriched atoms of the inactivator moiety with those of model compounds, it was confirmed that the alpha-diazoketone moiety is retained in DUO-inactivated dehydrase and that photoirradiation leads to Wolff rearrangement of the alpha-diazoketone moiety followed by attack of a nucleophile on the resulting ketene. Proteolytic degradation of photoirradiated; DUO-inactivated dehydrase gave peptides that were analyzed by Edman sequencing and by mass spectrometry. The results are consistent with a single protein modification (at H70), and attack on the ketene by water, leading to a carboxylic acid. Samples of intact native, DUO-inactivated, and photoirradiated, DUO-inactivated dehydrase were analyzed by electrospray ionization mass spectrometry, the results of which clearly support the hypothesis that the ketene suffers attack by water. In light of recent results from X-ray crystallography, it is proposed that the water that attacks the ketene is one of two bound water molecules with specific roles in the binding and/or catalytic turnover of substrate. A Michael addition-elimination mechanism is presented to explain the unexpected hydrolytic lability of the DUO-dehydrase adduct.

  Recent advances in the structural study of fatty acid synthase (FAS) and polyketide synthase (PKS) biosynthetic enzymes have illuminated our understanding of modular enzymes of the acetate pathway. However, one significant and persistent challenge in such analyses is resolution of the acyl carrier protein (ACP), a small (similar to 9 kDa) protein to which biosynthetic intermediates are tethered throughout the biosynthetic cycle. Here we report a chemoenzymatic crosslinking strategy in which the installation of a historical suicide substrate scaffold upon the 4'-phosphopantetheine (PPant) arm of the ACP is used to capture the active site of acyl carrier protein dehydratase (DH) domains in FAS. Through the synthesis of a small panel of related probes we identify structural features essential for ACP-DH crosslinking, and apply gel-based assays to demonstrate the stability as well as purification strategies for isolation of the chemoenzymatically modified ACP. Applying these carrier protein crosslinking techniques to the structural analysis of FAS and PKS complexes has the potential to provide snapshots of these biosynthetic assembly lines at work.
