Mutations in PurBox1 of the Bacillus subtilis pur operon control site affect adenine-regulated expression in vivo
《Science China(Life Sciences)》2005年第2期133-138,共6页Howard Zalkin 
This work was supported by the National Natural Science Foundation of China(Grant No.30070419).
Transcription of the Bacillus subtilis pur operon is regulated by a purine repressor (PurR)-DNA control site interaction. The pur operon control site has two PurBoxes that are re- quired for high-affinity PurR binding...
