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 isExpand
Solution NMR structure of the TatA component of the twin-arginine protein transport system from gram-positive bacterium Bacillus subtilis.
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 bacteriaExpand
Conserved regulatory elements in AMPK
arising from B. Xiao et al. 472, 230–233 (2011)10.1038/nature09932The AMP-activated protein kinase (AMPK), an αβγ heterotrimeric enzyme, has a central role in regulating cellular metabolism andExpand
Structural insight into poplar glutaredoxin C1 with a bridging iron-sulfur cluster at the active site.
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, anExpand
Solution structure of Escherichia coli glutaredoxin-2 shows similarity to mammalian glutathione-S-transferases.
Glutaredoxin 2 (Grx2) from Escherichia coli is distinguished from other glutaredoxins by its larger size, low overall sequence identity and lack of electron donor activity with ribonucleotideExpand
Structural basis for the phosphorylation of FUNDC1 LIR as a molecular switch of mitophagy
ABSTRACT Mitophagy is a fundamental process that determines mitochondrial quality and homeostasis. Several mitophagy receptors, including the newly identified FUNDC1, mediate selective removal ofExpand
Periplasmic Protein HdeA Exhibits Chaperone-like Activity Exclusively within Stomach pH Range by Transforming into Disordered Conformation*
The extremely acidic environment of the mammalian stomach, with a pH range usually between 1 and 3, represents a stressful challenge for enteric pathogenic bacteria such as Escherichia coli beforeExpand
Silencing of foreign DNA in bacteria.
Xenogeneic silencing proteins facilitate horizontal gene transfer by silencing expression of AT-rich sequences. By virtue of their activity these proteins serve as master regulators of a variety ofExpand
Dissection of Influenza A Virus M1 Protein: pH-Dependent Oligomerization of N-Terminal Domain and Dimerization of C-Terminal Domain
Background The matrix 1 (M1) protein of Influenza A virus plays many critical roles throughout the virus life cycle. The oligomerization of M1 is essential for the formation of the viral matrix layerExpand
