Stability of the Escherichia coli division inhibitor protein MinC requires determinants in the carboxy-terminal region of the protein.

abstract：:Crude cell extracts of Bacillus subtilis 168T exhibit enzyme activity capable of releasing free uracil from phage PBS1 deoxyribonucleic acid (DNA) in the presence of ethylenediaminetetraacetate. By measuring the enzyme activity in 300 clones that emanated from mutagenized cells, we obtained a mutant strain that did no...

abstract：:In Bacillus subtilis, the ermC gene encodes an mRNA that is unusually stable (40-min half-life) in the presence of erythromycin, an inducer of ermC gene expression. A requirement for this induced mRNA stability is a ribosome stalled in the ermC leader region. This property of ermC mRNA was used to study the decay of m...
