Report from Dagstuhl Seminar 12091 Principles of Provenance
This report documents the program and the outcomes of Dagstuhl Seminar 12091 “Principles of Provenance”. The term “provenance” refers to information about the origin, context, derivation, ownership or history of some artifact. In both art and science, provenance information is crucial for establishing the value of a real-world artifact, guaranteeing for example that the artifact is an original ...
متن کاملThiol/disulfide exchange between rabbit muscle phosphofructokinase and glutathione. Kinetics and thermodynamics of enzyme oxidation.
Reversible thiol/disulfide exchange equilibria between rabbit muscle phosphofructokinase and glutathione redox buffers results in a dependence of the activity of the enzyme on the thiol to disulfide ratio of the redox buffer (Gilbert, H. F. (1982) J. Biol. Chem. 257, 12086-12091). The transition between fully reduced (active) and fully oxidized (inactive) enzyme is half complete at a [GSH]/[GSS...
متن کاملAeropyrum camini sp. nov., a strictly aerobic, hyperthermophilic archaeon from a deep-sea hydrothermal vent chimney.
A novel hyperthermophilic archaeon, designated strain SY1(T), was isolated from a deep-sea hydrothermal vent chimney sample collected from the Suiyo Seamount in the Izu-Bonin Arc, Japan, at a depth of 1385 m. The cells were irregular cocci (1.2 to 2.1 micro m in diameter), occurring singly or in pairs, and stained Gram-negative. Growth was observed between 70 and 97 degrees C (optimum, 85 degre...
متن کاملDawn completes its mission at 4 Vesta
The Dawn mission was designed to test our hypothesis about the origin and evolution of the early solar system by visiting the largest differentiated basaltic asteroid, 4 Vesta, believed to be a survivor from the earliest times of rocky body formation. Observations from orbit show that Vesta is the parent body of the Howardite, Eucrite, Diogenite meteorites. Vesta has an iron core and a eucritic...
