Halpern, Yeheskel S. (Hebrew University-Hadassah Medical School, Jerusalem, Israel), and Meir Lupo. Glutamate transport in wild-type and mutant strains of Escherichia coli. J. Bacteriol. 90:1288-1295. 1965.-Mutants of Escherichia coli able to grow on glutamate as their source of carbon showed glutamate dehydrogenase and glutamate-oxaloacetate transaminase(More)
Transcription factors (TFs) operate by the combined activity of their DNA-binding domains (DBDs) and effector domains (EDs) enabling the coordination of gene expression on a genomic scale. Here we show that in vivo delivery of an engineered DNA-binding protein uncoupled from the repressor domain can produce efficient and gene-specific transcriptional(More)
Genetically related Escherichia coli K-12 strains were found to differ widely in their l-glutamic acid decarboxylase (GAD) activity. This variation is due to differences in the amount of GAD produced by the different cultures, rather than to the appearance of altered enzymes differing in catalytic activity. A regulatory gene, gadR, which controls the amount(More)
