Active site loop conformation regulates promiscuous activity in a lactonase from Geobacillus kaustophilus HTA426

Enzyme promiscuity is a prerequisite for fast divergent evolution of biocatalysts. A phosphotriesterase-like lactonase (PLL) from Geobacillus kaustophilus HTA426 (GkaP) exhibits main lactonase and promiscuous phosphotriesterase activities. To understand its catalytic and evolutionary mechanisms, we investigated a “hot spot” in the active site by saturation mutagenesis as well as X-ray crystallographic analyses. We found that position 99 in the active site was involved in substrate discrimination. One mutant, Y99L, exhibited 11-fold improvement over wild-type in reactivity (kcat/Km) toward the phosphotriesterase substrate ethyl-paraoxon, but showed 15-fold decrease toward the lactonase substrate delta-decanolactone, resulting in a 157-fold inversion of the substrate specificity. Structural analysis of Y99L revealed that the mutation causes a ?6.6 A outward shift of adjacent loop 7, which may cause increased flexibility of the active site and facilitate accommodation and/or catalysis of organophosphate substrate. This study provides for the PLL family an example of how the evolutionary route from promiscuity to specificity can derive from very few mutations, which promotes alteration in the conformational adjustment of the active site loops, in turn draws the capacity of substrate binding and activity.

Synthesis of Densely Functionalized Pyrimidouracils by Nickel(II)-Catalyzed Isocyanide Insertion

A robust nickel-catalyzed oxidative isocyanide insertion/C-H amination by reaction of readily available N-uracil-amidines with isocyanides affording polysubstituted pyrimidouracils has been reported. The reaction proceeds in moderate to quantitative yield, under mild conditions (i.e., green solvent, air atmosphere, moderate temperature). The broad range of structurally diverse isocyanides and N-uracil-amidines that are tolerated make this method an interesting alternative to the currently available procedures toward pyrimidouracils.

2-HYDROXY-1-OXO 1,2 DIHYDRO ISOQUINOLINE CHELATING AGENTS

The invention provides a new class of strongly chelating multidentate ligands based on a 2-hydroxy-1-oxo-1,2-dihydro-isoquinoline-3-carboxylic acid scaffold (hereafter 1,2-HOIQO) in combination with polyamine backbones. The extremely stable bidentate 1,2- HOIQO moiety can be synthesized by standard synthetic methodology on a large scale. An advantageous feature is the possibility to introduce a wide range of substituents on the benzene ring by standard transformations (like electrophilic aromatic substitutions). This allows, for example, for the tuning of chemical, photophysical, and solubility properties, as well as the attachment of functional moieties, relevant for sensing and imaging applications (e.g. DNA, proteins, antibodies, fluorophores, etc.). The combination of the 1,2-HOIQO chelators with polyamine backbones provides very strongly binding ligands for a variety of metals including first-row transition metals, lanthanides, actinides, etc. Metal complexes of this kind are expected to be useful in a number of applications (e.g. luminescence, MRI, actinide sequestering, metal chelation therapy, metal radioisotope labeling, etc.).

Effects of applying Lactobacillus helveticus H9 as adjunct starter culture in yogurt fermentation and storage

Lactobacillus helveticus H9 is a probiotic bacterium originating from traditional Tibetan kurut. It has high angiotensin-converting enzyme-inhibitory (ACEI) and antihypertensive activities. We aimed to evaluate the effects of L. helveticus H9 supplementation in yogurt fermentation and storage. We monitored changes of multiple parameters over 28 d of storage at 4C; namely, pH, titratable acidity, free amino groups, ACEI activity, physical properties, volatile flavor compounds, and sensory quality. Supplementation of L. helveticus H9 enhanced fermented milk acidification and proteolysis, resulting in a shorter fermentation time. The H9 treatment significantly increased the ACEI activity of the fermented milks. Fifteen key volatile flavors were detected by solid-phase microextraction-gas chromatography-mass spectrometry across all samples. More alcohols, aldehydes, and nitrogenous compounds, especially acetoin and benzaldehyde, were detected in the H9-supplemented fermented milks. The human sensory scores for flavor and texture, but not appearance, were lower for the H9-supplemented fermented milks, particularly beyond 2 wk of cold storage. Our results will be of interest to the dairy industry for developing novel functional dairy products.

Direct Synthesis of 3-Acylindoles through Rhodium(III)-Catalyzed Annulation of N-Phenylamidines with alpha-Cl Ketones

In the present study, a novel synthetic strategy to directly produce versatile 3-acylindoles through Rh(III)-catalyzed C-H activation and annulation cascade of N-phenylamidines with alpha-Cl ketones was developed, in which alpha-Cl ketones serve as unusual one-carbon (sp3) synthons. This strategy features high regioselectivity, efficiency, wide substrate tolerance, and mild reaction conditions, which further underscore its synthetic utility in drug molecule synthesis.
