Abstract Background Psychiatric problems among college students on USA campuses are common. Little is known about similar problems in developing countries, particularly the Arab region. The goal of this study was to assess the frequency of selected p

Mutation and cloning of eryG, the structural gene for erythromycin O-methyltransferase from Saccharopolyspora erythraea, and expression of eryG in Escherichia coli

Autor: V E Luebke, J S Tuan, T. J. Paulus, L Katz, G. T. Maine, J. P. Dewitt

Publikováno v: Journal of Bacteriology. 172:2541-2546

A mutant strain derived by chemical mutagenesis of Saccharopolyspora erythraea (formerly known as Streptomyces erythreus) was isolated that accumulated erythromycin C and, to a lesser extent, its precursor, erythromycin D, with little or no productio

Publikováno v: Journal of Bacteriology. 172:2372-2383

We used a series of gene disruptions and gene replacements to mutagenically characterize 30 kilobases of DNA in the erythromycin resistance gene (ermE) region of the Saccharopolyspora erythraea chromosome. Five previously undiscovered loci involved i

Evidence for a sex factor in Streptomyces erythreus

Autor: J P DeWitt

Publikováno v: Journal of Bacteriology. 164:969-971

A lethal zygosis-sensitive mutant of Streptomyces erythreus, ER720, was isolated. Pocks were formed when spores of the parental type were plated on a lawn of ER720, suggesting the loss of a transmissible plasmid, SEP1, from this strain. Recombination
