- Effects of hydrostatic pressure on the quaternary structure and enzymatic activity of a large peptidase complex from Pyrococcus horikoshii
[作者:Rosenbaum, E; Gabel, F; Dura, MA; Finet, S; Clery-Barraud, C; Masson, P; Franzetti, B,期刊:Archives of Biochemistry and Biophysics , 页码:104-110 , 文章类型: Article,,卷期:2012年517-2]
- While molecular adaptation to high temperature has been extensively studied, the effect of hydrostatic pressure on protein structure and enzymatic activity is still poorly understood. We have studied the influence of pre...
- Ser-796 of beta-galactosidase (Escherichia coil) plays a key role in maintaining a balance between the opened and closed conformations of the catalytically important active site loop
[作者:Jancewicz, LJ; Wheatley, RW; Sutendra, G; Lee, M; Fraser, ME; Huber, RE,期刊:Archives of Biochemistry and Biophysics , 页码:111-122 , 文章类型: Article,,卷期:2012年517-2]
- A loop (residues 794-803) at the active site of beta-galactosidase (Escherichia coli) opens and closes during catalysis. The a and 13 carbons of Ser-796 form a hydrophobic connection to Phe-601 when the loop is closed wh...
- Transactivation of ABCG2 through a novel cis-element in the distal promoter by constitutive androstane receptor but not pregnane X receptor in human hepatocytes
[作者:Benoki, S; Yoshinari, K; Chikada, T; Imai, J; Yamazoe, Y,期刊:Archives of Biochemistry and Biophysics , 页码:123-130 , 文章类型: Article,,卷期:2012年517-2]
- A previous report demonstrated that treatment of human hepatocytes with phenobarbital, an activator of nuclear receptor constitutive androstane receptor (CAR), increases mRNA levels of an efflux transporter ABCG2, which ...
- Expression and characterization of the diheme cytochrome c subunit of the cytochrome bc complex in Heliobacterium modesticaldum
[作者:Yue, H; Kang, YS; Zhang, H; Gao, XL; Blankenship, RE,期刊:Archives of Biochemistry and Biophysics , 页码:131-137 , 文章类型: Article,,卷期:2012年517-2]
- Heliobacterium modesticaldum is a Gram-positive, anaerobic, anoxygenic photoheterotrophic bacterium. Its cytochrome bc complex (Rieske/cyt b complex) has some similarities to cytochrome b(6)f complexes from cyanobacteria...
- (19)F-heptuloses as tools for the non-invasive imaging of GLUT2-expressing cells
[作者:Malaisse, WJ; Zhang, Y; Louchami, K; Sharma, S; Dresselaers, T; Himmelreich, U; Novotny, GW; Mandrup-Poulsen, T; Waschke, D; Leshch, Y; Thimm, J; Thiem, J; Sener, A,期刊:Archives of Biochemistry and Biophysics , 页码:138-143 , 文章类型: Article,,卷期:2012年517-2]
- Suitable analogs of D-mannoheptulose are currently considered as possible tools for the non-invasive imaging of pancreatic islet insulin-producing cells. Here, we examined whether (19)F-heptuloses could be used for non-i...
- MutL associates with Escherichia coli RecA and inhibits its ATPase activity
[作者:Zhang, M; Zhou, Y; Li, T; Wang, HL; Cheng, F; Zhou, YF; Bi, LJ; Zhang, XE,期刊:Archives of Biochemistry and Biophysics , 页码:98-103 , 文章类型: Article,,卷期:2012年517-2]
- Different DNA repair systems are known to cooperate to deal with DNA damage. However, the regulatory role of the cross-talk between these pathways is unclear. Here, we have shown that MutL, an essential component of mism...
