Studies on Escherichia coli tryptophan repressor-operator interactions
Trp repressor regulates the expression of TrpEDCBA, aroH, and TrpR operons. Recently, X-ray crystallographic analysis of a Trp repressor-operator complex has suggested a stoichiometry of one repressor dimer to one operator ...
A host-shutoff early gene of Bacillus subtilis bacteriophage SPO1
Shutoff of host biosynthesis is one of the earliest and most dramatic events occurring in viral infection and requires the expression of viral early genes. To understand the mechanisms of bacteriophage SPO1 induced ...
