The synthesis of tRNA by yeast RNA polymerase III (Pol III) is regulated in response to changing environmental conditions. This control is mediated by Maf1, the global negative regulator of Pol III transcription conserved from yeast to humans. Details regarding the molecular basis of Pol III repression by Maf1 are now emerging from recently reported structural and biochemical data on Pol III an...

How do state and protester violence affect whether protests grow or shrink? Previous research finds conflicting results for how affects protest dynamics. This article argues that expectations emotions should generate an n-shaped relationship between the severity of repression changes in size next day. Protester reduce appeal protesting increase expected cost protesting, decreasing subsequent si...

Inducer exclusion was not important in catabolite repression of the Bacillus subtilis gnt operon. The CcpA protein (also known as AlsA) was found to be necessary for catabolite repression of the gnt operon, and a mutation (crsA47, which is an allele of the sigA gene) partially affected this catabolite repression.
