| 1 | Atomic Fe-Zn dual-metal sites for high-efficiency pH-universal oxygen reduction catalysis显示文摘An effective electrocatalyst being highly active in all pH range for oxygen reduction reaction(ORR)is crucial for energy conversion and storage devices.However,most of the high-efficiency ORR catalysis was reported in alkaline conditions.Herein,we demonstrated the preparation of atomically dispersed Fe-Zn pairs anchored on porous N-doped carbon frameworks(Fe-Zn-SA/NC),which works efficiently as ORR catalyst in the whole pH range.It achieves high half-wave potentials of 0.78,0.85 and 0.72 V in 0.1 M HClO4,0.1 M KOH and 0.1 M phosphate buffer saline(PBS)solutions,respectively,as well as respectable stability.The performances are even comparable to Pt/C.Furthermore,when assembled into a Zn-air battery,the high power density of 167.2 mWcm−2 and 120 h durability reveal the feasibility of Fe-Zn-SA/NC in real energy-related devices.Theoretical calculations demonstrate that the superior catalytic activity of Fe-Zn-SA/NC can be contributed to the lower energy barriers of ORR at the Fe-Zn-N6 centers.This work demonstrates the potential of Fe-Zn pairs as alternatives to the Pt catalysts for efficient catalytic ORR and provides new insights of dual-atom catalysts for other energy conversion related catalytic reactions. | Jie Xu Shuhua Lai Defeng Qi Min Hu Xianyun Peng Yifan Liu Wei Liu Guangzhi Hu Heng Xu Fan Li Chao Li Jia He Longchao Zhuo Jiaqiang Sun Yuan Qiu Shusheng Zhang Jun Luo Xijun Liu | 2021 | Nano Research2021，14，5： | 6 |

| 7 | pyrG is required for maintaining stable cellular uracil level and normal sporulation pattern under excess uracil stress in Aspergillus nidulans显示文摘Tight control of the intracellular uracil level is believed to be important to reduce the occurrence of uracil incorporation into DNA.The pyrG gene of Aspergillus nidulans encodes orotidine 5'-phosphate decarboxylase,which catalyzes the conversion of orotidine monophosphate(OMP) to uridine monophosphate(UMP).In this study,we found that pyrG is critical for maintaining uracil at a low concentration in A.nidulans cells in the presence of exogenous uracil.Excess uracil and its derivatives had a stronger inhibitory effect on the growth of the pyrG89 mutant with defective OMP decarboxylase activity than on the growth of wild type,and induced sexual development in the pyrG89 mutant but not in wild type.Analysis of transcriptomic responses to excess uracil by digital gene expression profiling(DGE) revealed that genes related to sexual development were transcriptionally activated in the pyrG89 mutant but not in wild type.Quantitative analysis by HPLC showed that the cellular uracil level was 6.5 times higher in the pyrG89 mutant than in wild type in the presence of exogenous uracil.This study not only provides new information on uracil recycling and adaptation to excess uracil but also reveals the potential effects of OMP decarboxylase on fungal growth and development. | SUN XianYun ZHU JuFen BAO Li HU ChengCheng JIN Cheng HARRIS Steven D.

| 8 | Versatile functions of RNA m6A machinery on chromatin显示文摘m6A,a conserved and abundant modification on RNA,regulates RNA processing and function.RNA m6A machinery,including writers,erasers,and readers of m6A,is indispensable for m6A installation and function.Intriguingly,recent studies have revealed that m6A machinery can be recruited to chromatin by pleiotropic factors,including nascent RNA,transcription factors,regulatory RNA,histone modifications,and epigenetic machinery.Consequently,recruitment of m6A machinery can directly regulate chromatin biology,such as transcription,DNA damage repair,and DNA recombination beyond installation of m6A on nascent mRNA.Here,we discuss recent evidence showing that m6A machinery is targeted to chromatin and the direct biological consequences along with the underlying mechanisms. | Tanjing Song Suli Lv Neng Li Xuefeng Zhao Xianyun Ma Yingying Yan Weixia Wang Lidong Sun | 2022 | Journal of Molecular Cell Biology2022，14，3： | 0 |
