Cloning and characterization of the streptothricin-resistance gene which encodes streptothricin acetyltransferase from Streptomyces lavendulae.
The streptothricin-resistance gene of Streptomyces lavendulae No. 1080 was cloned in S. lividans using pIJ41 as a vector. From subcloning experiments, the 1.6 kb BamH I fragment was determined to encode the structural gene. The cell extracts of S. lividans carrying the gene on the plasmid pKS7 had activity to inactivate streptothricin in the presence of S-acetyl coenzyme A, indicating that the ...
متن کاملNew streptothricin-group antibiotics, AN-201 I, II and III. II. Chemical structures.
The new, belonging to the streptothricin-group antibiotics AN-201 I, II and III were found to be produced by a soil actinomycete identified as Streptomyces nojiriensis C-13. The chemical structures and the physical and spectroscopic properties of these compounds are reported here. On the basis of NMR and fast atom bombardment mass spectrometry (FAB-MS) spectra the antibiotics were identified as...
متن کاملAnalytical method for streptothricin-type antibiotics: structure of antibiotic LL-BL136.
An analytical procedure was devised which can distinguish members of the streptothricin family of antibiotics. It is based upon an analysis of the hydrolysis products of the antibiotics using a Technicon amino acid autoanalyzer under special conditions. The various fragments including the different streptolidine-amino sugar compounds were well resolved. A basic water-soluble antibiotic discover...
متن کاملAction of streptothricin F on ribosomal functions.
The effect of streptothricin F on elongation factor-dependent and on elongation factor-free translation systems was studied. Streptothricin F inhibits factor-dependent as well as factor-free polypeptide synthesis. The results suggest that streptothricin F inhibits polypeptide synthesis via interaction with the ribosome. In partial reactions streptothricin F impairs EF-G-dependent translocation ...
