1Crystal structures of D-psicose 3-epimerase from Clostridium cellulolyticum H10 and its complex with ketohexose sugars显示文摘D-Psicose 3-epimerase(DPEase)is demonstrated to be useful in the bioproduction of D-psicose,a rare hexose sugar,from D-fructose,found plenty in nature.Clostridium cellulolyticum H10 has recently been identified as a DPEase that can epimerize D-fructose to yield D-psicose with a much higher conversion rate when compared with the conventionally used DTEase.In this study,the crystal structure of the C.cellulolyticum DPEase was determined.The enzyme assembles into a tetramer and each subunit shows a(β/α)8 TIM barrel fold with a Mn2+metal ion in the active site.Additional crystal structures of the enzyme in complex with substrates/products(D-psicose,D-fructose,D-tagatose and D-sorbose)were also determined.From the complex structures of C.cellulolyticum DPEase with D-psicose and D-fructose,the enzyme has much more interactions with D-psicose than D-fructose by forming more hydrogen bonds between the substrate and the active site residues.Accordingly,based on these ketohexosebound complex structures,a C3-O3 proton-exchange mechanism for the conversion between D-psicose and D-fructose is proposed here.These results provide a clear idea for the deprotonation/protonation roles of E150 and E244 in catalysis.Hsiu-Chien Chan Yueming Zhu Yumei Hu Tzu-Ping Ko Chun-Hsiang Huang Feifei Ren Chun-Chi Chen Yanhe Ma Rey-Ting Guo Yuanxia Sun 2012Protein & Cell2012,3,2:6

20Tactfully revealing the working mechanisms on a tetraarylimidazole derivative:AIE characteristic,ESIPT process and ICT effect integrating in one molecule显示文摘Recently,a novel tetraarylimidazole derivative 2-(benzo[d]thiazol-2-yl)-4-(4,5-bis(4-methoxyphenyl)-1-phenyl-1H-imidazol-2-yl)-phenol(be called MHBT herein)was architectured by our research group showing the fascinating synergy of aggregation-induced emission(AIE)characteristic,excited-state intramolecular proton transfer(ESIPT)mechanism and intramolecular charge transfer(ICT)effect.Nevertheless,a detailed and reasonable interpretation of its mechanisms both in theory is urgently needed.Consequently,to unveil the working mechanism meticulously,herein,we tactfully applied density functional theory(DFT)and time-dependent density functional theory(TD-DFT)methods to illuminate the underlying mechanisms in different solvent conditions.After optimizing the structures,the geometric parameters of hydrogen bonds(HBs),the infrared(IR)vibrational spectrum,the reduced density gradient(RDG)isosurfaces were calculated in detail,vividly explaining how the enhancement of HBs behaved as the driving force to proceed ESIPT process.Simultaneously,the frontier molecular orbitals(FMOs)combined with the potential energy curves(PECs)were conducted to interpretate the role and character of ICT and ESIPT in molecule MHBT.Further,the PECs of MHBT for dihedral angles in different organic solvents were calculated to compare the dominant torsion degree,rationalizing the AIE phenomenon from the view of the restriction of intramolecular rotation process.This work may well underpin the understanding of the interaction between different mechanisms in fluorescent dyes and thereby provide meaningful guideline for the design and construction of ideal molecules.Min Liu Shibo Zhong Bin Feng Yueming Ren Xiaohui Liu Shuaige Bai Fei Chen Shao Liu Wenbin Zeng 2023Chinese Chemical Letters2023,34,8:0
