The twin-arginine transport (Tat) system translocates folded proteins across the bacterial cytoplasmic or chloroplast thylakoid membrane of plants. The Tat system in most Gram-positive bacteria consists of two essential components, the TatA and TatC proteins. TatA is considered to be a bifunctional subunit, which can form a protein-conducting channel by(More)
Glutaredoxins are glutathione-dependent enzymes that function to reduce disulfide bonds in vivo. Interestingly, a recent discovery indicates that some glutaredoxins can also exist in another form, an iron-sulfur protein [Lillig, C. H., et al. (2005) Proc. Natl. Acad. Sci. U.S.A. 102, 8168-8173]. This provides a direct connection between glutaredoxins and(More)
= 4 16 64 256, etc.) show that the analytical method can accurately estimate the system performance. Moreover, numerical results show that with the antenna-diversity technique, the BER performance improves significantly, especially in perfect channel-estimation cases. It is also found that the channel-estimation error limits the benefit of antenna(More)
The effect of five constant temperatures (16, 20, 24, 28 and 32°C) on the development, survival and reproduction of Neoseiulus barkeri Hughes fed on Aleuroglyphus ovatus Toupeau (Acari: Acaridae) was examined in the laboratory at 85% relative humidity. Development time of different immature stages decreased with increasing temperature, total egg-to-adult(More)
H-NS and Lsr2 are nucleoid-associated proteins from Gram-negative bacteria and Mycobacteria, respectively, that play an important role in the silencing of horizontally acquired foreign DNA that is more AT-rich than the resident genome. Despite the fact that Lsr2 and H-NS proteins are dissimilar in sequence and structure, they serve apparently similar(More)
Spectral processing and post-experimental data analysis are the major tasks in NMR-based metabonomics studies. While there are commercial and free licensed software tools available to assist these tasks, researchers usually have to use multiple software packages for their studies because software packages generally focus on specific tasks. It would be(More)
Bimolecular fluorescence complementation (BiFC) has been widely used in the analysis of protein-protein interactions (PPIs) in recent years. There are many notable advantages of BiFC such as convenience and direct visualization of PPI in cells. However, BiFC has one common limitation: the separated non-fluorescent fragments can be spontaneously(More)
H-REV107 is a Ca(2+)-independent phospholipase A(1/2), and it is also a pro-apoptosis protein belonging to the novel class II tumor suppressor family, H-REV107-like family. Here we report the solution structure of the N-terminal catalytic domain of human H-REV107, which has a similar architecture to classical NlpC/P60 domains, even though their fold(More)
