Zusammenfassung Die Struktur desp-Bromphenylhydrazids der Byssochlamsäure, des charakteristischen Stoffwechselproduktes vonByssochlamys fulva, wurde durch dreidimensionale Röntgenanalyse bestimmt. Die Resultate stellen eine Bestimmung der Konstitution und Stereochemie (abgesehen von der absoluten Konfiguration) desp-Bromphenylhydrazids als (I) und demnach der Byssochlamsäure als (II) dar. 相似文献

We used an exome-sequencing strategy and identified an allelic series of NOTCH2 mutations in Hajdu-Cheney syndrome, an autosomal dominant multisystem disorder characterized by severe and progressive bone loss. The Hajdu-Cheney syndrome mutations are predicted to lead to the premature truncation of NOTCH2 with either disruption or loss of the C-terminal proline-glutamate-serine-threonine-rich proteolytic recognition sequence, the absence of which has previously been shown to increase Notch signaling. 相似文献

The Hubble Deep Field provides one of the deepest multiwavelength views of the distant Universe and has led to the detection of thousands of galaxies seen throughout cosmic time. An early map of the Hubble Deep Field at a wavelength of 850?micrometres, which is sensitive to dust emission powered by star formation, revealed the brightest source in the field, dubbed HDF?850.1 (ref. 2). For more than a decade, and despite significant efforts, no counterpart was found at shorter wavelengths, and it was not possible to determine its redshift, size or mass. Here we report a redshift of z = 5.183 for HDF?850.1, from a millimetre-wave molecular line scan. This places HDF?850.1 in a galaxy overdensity at z?≈?5.2, corresponding to a cosmic age of only 1.1?billion years after the Big Bang. This redshift is significantly higher than earlier estimates and higher than those of most of the hundreds of submillimetre-bright galaxies identified so far. The source has a star-formation rate of 850 solar masses per year and is spatially resolved on scales of 5 kiloparsecs, with an implied dynamical mass of about 1.3?×?10(11) solar masses, a significant fraction of which is present in the form of molecular gas. Despite our accurate determination of redshift and position, a counterpart emitting starlight remains elusive. 相似文献

Summary Methanolic extracts ofCortinarius speciosissimus yielded a fluorescent compound which was crystallized and shown to be a cyclic polypeptide. The compound, or an analogue, has been found in most members of the genusCortinarius.The authors acknowledge the help of Dr M.
