A novel macromolecular antibiotic, SN-07. Taxonomy of producing organism, isolation, characterization and biological activities.
A novel macromolecular antibiotic SN-07 was obtained from the cultural supernatant of Actinomadura roseoviolacea var. miuraensis nov. var. The antibiotic was soluble in water, had a molecular weight of 18,000-22,000 daltons in 50 mM Tris-HCl buffer, pH 7.0, containing 2.0 M KCl as compared with authentic proteins. Its major constituents were nucleic acids. The substance had antibacterial activi...
متن کاملIsospin dependent multi - fragmentation in 112 Sn + 112 Sn and 124 Sn + 124 Sn collisions
Significant differences in the relationships between fragment, neutron, and charged particle multiplicities were found between Sn+Sn and Sn+Sn collisions at 40 MeV/A. In this paper we explore the possibility to explain this phenomenon in the framework of percolation models, and find, that the results are only reproducible in part.
متن کاملIsospin dependent multifragmentation in 112 Sn 1 112 Sn and 124 Sn 1 124 Sn collisions
Percolation models have proven highly successful in the simulation of multifragmentation reactions in the past @1,2#. Within these models, fragmentation is described by first distributing a set of points or sites, each representing a nucleon, on a three-dimensional lattice, which represents the bonds between the sites. In the case of a simple rectangular lattice, each site is connected to six n...
متن کاملConformation studies on and assessment by spectral analysis of the protein-chromophore interaction of the macromolecular antitumor antibiotic C-1027.
Characterization of the secondary structure of the antitumor antibiotic C-1027 has been made from a comparison of C-1027 and its apoprotein by various analytical means. The results indicated the antibiotic to be abundant in beta-structure by measurements of Fourier-transform infrared (FT-IR) spectroscopy and the circular dichroism (CD) spectrum, and by a prediction of the secondary structure ba...
متن کاملDECOMPOSITION OF THE DIAGONAL ACTION OF Sn ON THE COINVARIANT SPACE OF Sn × Sn
The purpose of this paper is to give an explicit description of the irreducible decomposition of the multigraded Sn-module of coinvariants of Sn×Sn. Many of the results presented can be extended to S n , and analogous questions for other finite reflection group.
