To avoid random chemical linkage and achieve precisely directed immobilization, mutant enzymes were obtained and immobilized using an incorporated reactive nonstandard amino acid (NSAA). For this purpose, aldehyde ketone reductase (AKR) was used as a model enzyme, and 110Y, 114Y, 143Y, 162Q and 189Q were each replaced with p-azido-l-phenylalanine (pAzF). Then, the mutant AKR was coupled to the functionalized support by strain-promoted alkyne-azide cycloaddition (SPAAC). The effects of the incorporation number and site of NSAAs on the loading and thermal stability of the immobilized AKR were examined. The results show that the mutant enzymes presented better specific activity than the wild type, except for AKR-110Y, and AKR-114Y showed 1.16-fold higher activity than the wild type. Moreover, the half-life (t1/2) of the five-point immobilized AKR reached 106 h and 45 h, 13 and 7 times higher than that of the free enzyme at 30 C and 60 C, respectively. Comparison of these three types of enzymes shows that multi-point immobilization provides improved loading and thermal stability and facilitates one-step purification. We expect this platform to facilitate a fundamental understanding of precisely oriented and controllable covalent immobilization and enable bio-manufacturing paradigms for fine chemicals and pharmaceuticals.

Fried allium oil has been widely used in traditional Chinese home cooking and recently has grown in popularity in the food manufacturing industry. Thus, physical and chemical changes during frying process were measured to investigate the flavor formation mechanism in green onion (Allium fistulosum L.) deep-fried oil. With the increase of the oil temperature, important variations took place when the temperature rose above 140 C during the whole frying process. A detailed study of these changes was made from both macro and micro aspects. From a macro perspective, sensory attributes including burnt, fried, oily, cooked vegetable and salty were strengthened. Meanwhile, the reference points of the oil samples on the fingerprint chart were distinguishable from others by electronic nose. In addition, contents of furans and furanones, sulfur-containing compounds, aldehydes and alcohols increased sharply according to SAFE-GC-MS analysis from a microscopic point of view, and contents of unsaturated fatty acids dropped remarkably while the saturated ones increased. These changes were considered to be caused by interactions between carbohydrates, proteins and fats in the deep-fried system and thermo degradations of sugars, amino acids and fats. The results indicated that the stage, when frying at temperatures ranging from 140 C to 165 C, was the most significant period for the flavor formation of the deep-fried oil.

The direct alpha-arylation of cyclic and acyclic ethers with heteroarenes has been accomplished through the design of a photoredox-mediated C – H functionalization pathway. Transiently generated alpha-oxyalkyl radicals, produced from a variety of widely available ethers through hydrogen atom transfer (HAT), were coupled with a range of electron-deficient heteroarenes in a Minisci-type mechanism. This mild, visible-light-driven protocol allows direct access to medicinal pharmacophores of broad utility using feedstock substrates and a commercial photocatalyst.
