Temperature-sensitive RNA polymerase of a mammalian cell mutant.
In our attempts to characterize a temperature-sensitive mutant (ts-2) of monkey kidney cell line BSC-i, we have provided evidence to show that the mutant was defective in the synthesis or processing of rRNA (45, 28 and 18 s) molecules at 39-5 °C and there was indication that the nucleolar RNA polymerase (I) or some factor associated with its functional activity was thermolabile at the restricte...
متن کاملA mutant of Escherichia coli with temperature-sensitive streptomycin protein.
The temperature-sensitive mutation in our Escherichia coli strain C1714 appears to be in a ribosomal protein. The mutation maps at the streptomycin locus. Protein synthesis in intact cells stops immediately when the temperature is shifted from 30 to 42 degrees C. Analysis of polyribosome distributions after shift-up suggests that initiation of protein synthesis is defective at the high temperat...
متن کاملTemperature-sensitive, colicin M-tolerant mutant of Escherichia coli.
A mutant sensitive to colicin M at 30 degrees C and tolerant at 42 degrees C to high concentrations of colicin M was isolated from Escherichia coli K-12. A temperature shift from 30 to 42 degrees C rescued all cells up to the time they started to lyse at 30 degrees C (25 min after addition of colicin M). The growth rate at 42 degrees C remained unaffected by colicin M. AT 42 degrees C the cell-...
متن کاملCharacterization of a temperature-sensitive DNA ligase from Escherichia coli.
DNA ligases are essential enzymes in cells due to their ability to join DNA strand breaks formed during DNA replication. Several temperature-sensitive mutant strains of Escherichia coli, including strain GR501, have been described which can be complemented by functional DNA ligases. Here, it is shown that the ligA251 mutation in E. coli GR501 strain is a cytosine to thymine transition at base 4...
متن کاملReplication of bacteriophage phiX174 DNA in a temperature-sensitive dnaC mutant of escherichia coli C.
Bacteriophage phiX174 cannot grow in a temperature-sensitive dnaC mutant of Escherichia coli C at the nonpermissive temperature. The inability to grow is the result of inhibition of virus DNA synthesis. Parental replicative form synthesis is not temperature sensitive. Single-stranded virus DNA continues to be synthesized for at least 45 min after shifting to the nonpermissive temperature late i...
