A joint-team from China Agriculture University has gained insight into the mysterious structure and function of MoSub1,the Sub1 homology from rice blast fungus. The structure of the protein shows high structure similarity with the structure of PC4 and has a similar dimer interface and DNA binding region to PC4,indicating that MoSub1 could bind DNA using the same motif as other proteins of the Sub1/PC4 family. The ...

The Maikun Teng and Liwen Niu groups from University of Science and Technology of China collected a set of 2.5□□ diffraction data of Saccharomyces cerevisiae Cdc73 under the assistance of the staff on beamline 3W1A of the Beijing Synchrotron Radiation Facility and solved the structure by using the heavy atom iodine anomalous scattering data. Arndt,Andrew P. Article:Hongkai Chen,Nuo Shi,Yongxiang Gao,Xu Li,Maiku...

RNA-binding properties of NTD and CTD characterized by both gel electrophoresis mobility shift assays and isothermal titration calorimetry showed NTD could bind RNA independently and RNA binding was achieved by NTDaccomplished by coordinating role of CTD. Single wavelength anomalous data(SAD)from seleno-RlmG crystals were collected on the beamline station 3W1A of BSRF and the RlmG-AdoMet comolex structure was dete...

The fully activated RSK is thus able to phosphorylate downstream substrates to modulate diverse cellular processes. Xiao-Dong Su from Peking University has gained insight into the structure and function of human RSK1 CTKD. (a)Superimposition of ATP binding cleft of RSK1 CTKD(cyan)and PKA(orange。 The missing regions are indicated by dotted lines. The atomic structure of human RSK1 CTKD is of great interest for the...

A team from Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences, used synchrotron based X-ray absorption fine structure spectroscopy (XAFS) combining with some other technologies such as ICP-MS, X-ray diffraction (XRD) and high resolution transmission electronic microscopy (HRTEM) to analyze the speciation and microstructural transformation of ZnO NPs in the presence of phosphate which exis...

Many studies have proven that the ammonium thiosulfate can enhance the mercury accumulation in plant through which they can meet the standard of accumulators or even hyperaccumulators. However,the mechanism of mercury transport and accumulation in plant as a result of ammonium thiosulfate has not been identified yet. Researchers from Institute of Geochemistry,CAS have studied the mercury speciation in thiosulfate ...
