| 1 | Revisiting the Concentration Observations and Source Apportionment of Atmospheric Ammonia显示文摘While China’s Air Pollution Prevention and Control Action Plan on particulate matter since 2013 has reduced sulfate significantly,aerosol ammonium nitrate remains high in East China.As the high nitrate abundances are strongly linked with ammonia,reducing ammonia emissions is becoming increasingly important to improve the air quality of China.Although satellite data provide evidence of substantial increases in atmospheric ammonia concentrations over major agricultural regions,long-term surface observation of ammonia concentrations are sparse.In addition,there is still no consensus on whether agricultural or non-agricultural emissions dominate the urban ammonia budget.Identifying the ammonia source by nitrogen isotope helps in designing a mitigation strategy for policymakers,but existing methods have not been well validated.Revisiting the concentration measurements and identifying source apportionment of atmospheric ammonia is thus an essential step towards reducing ammonia emissions. | Yuepeng PAN Mengna GU Yuexin HE Dianming WU Chunyan LIU Linlin SONG Shili TIAN Xuemei LÜ Yang SUN Tao SONG Wendell WWALTERS Xuejun LIU Nicholas AMARTIN Qianqian ZHANG Yunting FANG Valerio FERRACCI Yuesi WANG | 2020 | Advances in Atmospheric Sciences2020，37，9： | 4 |

| 15 | Crystal structures and biochemical studies of human lysophosphatidic acid phosphatase type 6显示文摘Lysophosphatidic acid(LPA)is an important bioac-tive phospholipid involved in cell signaling through G-protein-coupled receptors pathways.It is also involved in balancing the lipid composition inside the cell,and modulates the function of lipid rafts as an intermediate in phospholipid metabolism.Because of its involvement in these important processes,LPA degradation needs to be regulated as precisely as its production.Lysophospha-tidic acid phosphatase type 6(ACP6)is an LPA-specifi c acid phosphatase that hydrolyzes LPA to monoacylglyc-erol(MAG)and phosphate.Here,we report three crystal structures of human ACP6 in complex with malonate,L-(+)-tartrate and tris,respectively.Our analyses revealed that ACP6 possesses a highly conserved Rossmann-fold-like body domain as well as a less conserved cap domain.The vast hydrophobic substrate-binding pocket,which is located between those two domains,is suitable for ac-commodating LPA,and its shape is different from that of other histidine acid phosphatases,a fact that is consistent with the observed difference in substrate preferences.Our analysis of the binding of three molecules in the active site reveals the involvement of six conserved and crucial residues in binding of the LPA phosphate group and its catalysis.The structure also indicates a water-supplying channel for substrate hydrolysis.Our structural data are consistent with the fact that the enzyme is active as a monomer.In combination with additional mutagenesis and enzyme activity studies,our structural data provide important insights into substrate recognition and the mechanism for catalytic activity of ACP6. | Jun Li Yu Dong Xingru Lü Lu Wang Wei Peng Xuejun C.Zhang Zihe Rao | 2013 | Protein & Cell2013，4，7： | 0 |
