THE APPARENT CONSERVATION OF THE INTERNAL LOW EFFICIENCY PROMOTER OF THE TRYPTOPHAN OPERONS OF SEVERAL SPECIES OF ENTEROBACTERIACEAE

The specific activities of the tryptophan biosynthetic enzymes were determined for eleven different species of Enterobacteriaceae grown under repressing and non-repressing conditions. In all the bacteria examined the multipliciy of derepression for the first two enzymes of the pathway was at least t...

More Information
Summary:The specific activities of the tryptophan biosynthetic enzymes were determined for eleven different species of Enterobacteriaceae grown under repressing and non-repressing conditions. In all the bacteria examined the multipliciy of derepression for the first two enzymes of the pathway was at least twofold greater than the multiplicity of derepression for the last three enzymes.
