Optical Identification of X-ray Sources in a High X-ray Flux Sensitivity area from the Rass
We have optically identified a complete sub-sample of ROSAT All-Sky Survey (RASS) X-ray sources contained in 6 study areas. Of the original 12°12° area near the NEP only one quarter was observed until now in o...

Structural Diversity and Functional Conservation of Soluble Inorganic Pyrophosphatases from Photosynthetic Prokaryotes and Plastids
Inorganic pyrophosphatases (sPPase; pyrophosphate phosphohydrolase, EC 3.6.1.1) are essential enzymes found in the cytosol and cellular organelles that drive anabolism through the hydrolysis of the energy-nch ...

Evidence for the Widespread Distribution of Membrane-Bound Inorganic Pyrophosphatasfs among Photosyntheiic Prokaryotes
Two types of proton-pum**, membrane-bound inorganic pyrophosphatases (PPases), both from photosynthetic organisms, have been characterized to date and their genes cloned: the vacuolar PPase (V-PPase) of high...

The New Ultrashort-Period Cataclysmic Variable RX J0757.0+6306
A new cataclysmic variable is identified as the optical counterpart of the X-ray source RX J0757.0+6306. The emission lines bear evidence of a strong disc with an S-wave with period of 75±1.4 min, which we ide...
