The Uncommon Enzymology of Cis-Acyltransferase Assembly Lines

The enzymology of 135 assembly lines containing primarily cis-acyltransferase modules is comprehensively analyzed, with greater attention paid to less common phenomena. Diverse online transformations, in which the substrate and/or product of the reaction is an acyl chain bound to an acyl carrier protein, are classified so that unusual reactions can be compared and underlying assembly-line logic can emerge. As a complement to the chemistry surrounding the loading, extension, and offloading of assembly lines that construct primarily polyketide products, structural aspects of the assembly-line machinery itself are considered. This review of assembly-line phenomena, covering the literature up to 2017, should thus be informative to the modular polyketide synthase novice and expert alike.

Remote Effects Modulating the Spin Equilibrium of the Resting State of Cytochrome P450cam – An Investigation Using Active Site Analogues

The crystal structure of the resting state of cytochrome P450 cam (CYP101), a heme thiolate protein, shows a cluster of six water molecules in the substrate binding pocket, one of which is coordinating to iron(III) as sixth ligand. The resting state is low-spin and changes to high-spin when substrate camphor binds and H2O is removed. In contrast to the protein, previously synthesised enzyme models such as H 2O-FeIII(porph)(ArS-) were shown to be purely high-spin. Iron(S-)porphyrins with different distal sites mimicking proposed remote effects have been prepared and studied by cw-EPR. The results indicate that the low-spin of the resting state of P450cam is due to the fact that the water molecule coordinating to iron has an OH –like character because of hydrogen bonding and polarisation of the water cluster, respectively.

The invention discloses a synthetic method for 3-hydroxylmethal tetrahydrofuran. The synthetic method comprises the following steps: with 2-chloroethanol and diethyl malonate as raw materials, reacting under the action of alkaline in the presence of an organic solvent or in absence of a solvent to obtain an intermediate 2-ethoxy-diethyl succinate; then, reducing the intermediate 2-ethoxy-diethyl succinate by virtue of metal borohydride to obtain 2-hydroxymethyl-1,4-butanediol; and finally, producing 3-hydroxylmethal tetrahydrofuran under the action of a dehydrating agent. According to the synthetic method, the usage amount of the reducing agent metal borohydride is remarkably lowered, and yield of a byproduct sodium metaborate is reduced at the same time. The invention provides the synthetic method for the drug intermediate 3-hydroxylmethal tetrahydrofuran.

Exudation of low molecular weight compounds (thiobismethane, methyl isocyanide, and methyl isothiocyanate) as a possible chemical defense mechanism in the marine sponge Ircinia felix

The volatile constituents of the marine sponge Ircinia felix were obtained by dynamic headspace extraction and analyzed by HRGC, HRGC-MS and HRGC-Odor at sniffing port, Fifty-nine volatiles were identified for the first time in the odor of this sponge. Hydrocarbons (32.9%), alcohols (17.8%) and carbonyl compounds (16.0%) predominated in the sponge volatile profile, followed by esters (11.6%), halogen compounds (8.6%), ethers (7.7%), nitrogen and/or sulfur compounds (4.6%) and carboxylic acids (0.8%). Among the identified volatiles, thiobismethane (commonly known as dimethylsulfide), methyl isocyanide and methyl isothiocyanate were found to be responsible for the nauseating and toxic smell emitted by the sponge and for the antimicrobial activity detected in the volatile extract. Exudation experiments in aquarium and in situ conditions revealed that thiobismethane, methyl isocyanide and methyl isothiocyanate are continuously released by the sponge. Upon injury, the concentration of these volatiles increased strongly. Hence, these substances form a chemical protective barrier which may help these sponges avoid fouling, compete for space, prevent infection in the short term, and/or signal generalist predators regarding the existence of other toxic substances in the internal tissues.

Irradiated ground beef patties: Dose and dose-age estimation by volatile compounds measurement

Volatile compounds produced by irradiation in ground beef patties, packaged under vacuum, were extracted by head-space solid-phase micro-extraction and quantified by gas-chromatography coupled to mass-spectrometry. The study was carried out at levels of irradiation, ranging from 0.5 to 8kGy. Among the 101 detected volatiles compounds, 25 resulted correlated with dose. On the basis of further measurements at 30 and 120 days after irradiation, the most stable compounds with time were identified. To estimate the dose just after irradiation, linear combinations of selections of possible dose markers were obtained via partial least squares regression. A further data analysis showed that it is possible to reconstruct both the irradiation dose and the time elapsed after irradiation from the ratio between the peak areas of some dose markers. The adopted experimental procedure combined with a proper data analysis may lead to dose or dose/age reconstruction in a rapid, simple and efficient way.
