- HetR, master regulator of heterocyst differentiation in the filamentous cyanobacterium Anabaena sp. strain PCC 7120, stimulates heterocyst differentiation via transcriptional autoregulation and is negatively regulated by...
- Exploring Weak, Transient Protein-Protein Interactions in Crowded In Vivo Environments by In-Cell Nuclear Magnetic Resonance Spectroscopy
[作者:Wang, QH; Zhuravleva, A; Gierasch, LM,期刊:Biochemistry, 页码:9225-9236 , 文章类型: Article,,卷期:2011年50-43]
- Biology relies on functional interplay of proteins in the crowded and heterogeneous environment inside cells, and functional protein interactions are often weak and transient. Thus, methods that preserve these interactio...
- Molecular Basis of the Cooperative Binding of Cu(I) and Cu(II) to the CopK Protein from Cupriavidus metallidurans CH34
[作者:Ash, MR; Chong, LX; Maher, MJ; Hinds, MG; Xiao, ZG; Wedd, AG,期刊:Biochemistry, 页码:9237-9247 , 文章类型: Article,,卷期:2011年50-43]
- The bacterium Cupriavidus metallidurans CH34 is resistant to high environmental concentrations of many metal ions. Upon copper challenge, it upregulates the periplasmic protein CopK (8.3 kDa). The function of CopK in the...
- Hydrogen/Deuterium Exchange and Electron-Transfer Dissociation Mass Spectrometry Determine the Interface and Dynamics of Apolipoprotein E Oligomerization
[作者:Huang, RYC; Garai, K; Frieden, C; Gross, ML,期刊:Biochemistry, 页码:9273-9282 , 文章类型: Article,,卷期:2011年50-43]
- Apolipoprotein E, a 34 kDa protein, plays a key role in triglyceride and cholesterol metabolism. Of the three common isoforms (ApoE2, -3, and -4), only ApoE4 is a risk factor for Alzheimer's disease. All three isoforms o...
