The twin-arginine translocation (Tat) protein export system is present in the cytoplasmic
membranes of most bacteria and archaea and has the highly unusual property of …

If the atmosphere of the early Earth was hydrogen-rich, 1 it is reasonable to think that
hydrogenases, the enzymes enabling cells to use molecular hydrogen, were probably …

Hydrogenases (H2ases) catalyze the reversible oxidation of molecular hydrogen and play a
central role in microbial energy metabolism. Most of these enzymes are found in Archaea …

Biological oxidation of hydrogen sulfide to sulfate is one of the major reactions of the global
sulfur cycle. Reduced inorganic sulfur compounds (referred to below as sulfur) are …

Nitrite is widely used by bacteria as an electron acceptor under anaerobic conditions. In
respiratory nitrite ammonification an electrochemical proton potential across the membrane …

Subcellular compartments have unique protein compositions, yet protein synthesis only
occurs in the cytosol and in mitochondria and chloroplasts. How do proteins get where they …

The Tat (t win‐a rginine t ranslocation) system is a bacterial protein export pathway with the
remarkable ability to transport folded proteins across the cytoplasmic membrane …

The twin-arginine translocation (Tat) pathway is responsible for the export of folded proteins
across the cytoplasmic membrane of bacteria. Substrates for the Tat pathway include redox …

The yeast two-hybrid system pioneered the field of in vivo protein-protein interaction
methods and undisputedly gave rise to a palette of ingenious techniques that are constantly …

The twin-arginine translocation (Tat) machinery of the Escherichia coli inner membrane is
