Gas phase x-ray photoelectron spectroscopy of some ketone compounds

Creator:: Situmeang, Rudy T. M.
Abstract:: The photoelectron spectra of a series of ketone compounds have been investigated in the gas phase. Core ionization energies were measured to probe the effects of molecular size and connectivity number on core ionization energies. It was found that core ionization energies roughly decrease with increasing connectivity number as expected....

Full Text:: shape. The goal of this work is to provide additional information on the effect of molecular size

Studies of the biosynthesis of Sarubicin A

Creator:: Eisenberg, Rodney L.
Abstract:: Early studies on the biosynthesis of Sarubicin A, 1, had suggested the intermediacy of the novel aromatic amino acid 6-hydroxyanthranilic acid, 17. To investigate the biosynthetic steps beyond 17, [¹³C-¹⁵N carboxamide] 6-hydroxyanthranilamide, 27a, was synthesized, and fed to fermentations of Streptomyces helicus. Incorporation of 27a into 1 provided suggestive evidence...

Purification of 2,5-dihydroxyacetanilide epoxidase and mechanism of hydroquinone epoxidases

Creator:: Kirchmeier, Marc J.
Abstract:: 2,5-dihydroxyacetanilide epoxidase from Streptomyces LL-C10037 (DHAE I) catalyzes the epoxidation of hydroquinone 4, to form epoxyquinone 7. DHAE I has been purified to homogeneity, with an overall purification factor greater than 23,000. N-terminal and internal amino acid sequences have been obtained from the purified enzyme so that the epoxidase gene...

Chemical and statistical analyses of chondrules from the Mokoia (CV3) meteorite

Creator:: Schilk, Alan J.
Abstract:: Nearly 100 chondrules were extracted from -8.6g of the Mokoia (CV3) meteorite and have been analyzed by sequential instrumental neutron activation analysis (INAA). The resulting data were utilized in a comprehensive statistical characterization of these objects and, unlike similar investigations, virtually no loss of relevant data was incurred due to...
