    Published 2016-01-01
    “…In contrast to DP experiments, only a small fraction of 13C nuclei in the plasma blacks are effectively cross-polarized from nearby 1H nuclei and are thus observed in spectra recorded with CP. 13C NMR spectra are thus useful to distinguish between different types of carbon species in plasma blacks and allow a selective study of groups spatially close to hydrogen in the material.…”

    Discovery and Characterization of Novel Esterases with Ethyl Carbamate-Hydrolyzing Activity by LIU Qingtao, ZHU Sibao, WANG Tianwen, LI Chuang, QIAN Senhe, ZHANG Wenqing, CHENG Fan, TIAN Shufang

    Published 2025-01-01
    “…Structural analysis indicated that the narrow substrate channel of ES9 might affect the entry of EC, thus affecting its maximum reaction rate (Vmax) toward EC; the relatively high affinity of ES9 for EC might be attributed to the strong hydrogen bonding between them. The EC-degrading esterases had good ethanol tolerance, which not only enrich the EC-hydrolyzing enzyme library, but also provide a new method for controlling the EC content in traditional fermented foods with low alcohol content.…”
