摘要：

The raffinose (raf) operon is negatively controlled by the specific binding of raf repressor (rafR gene) to raf operator (rafO) DNA. Both rafR and rafO have been sequenced. The 1,011-base-pair rafR gene encodes a 336-amino-acid polypeptide containing an N-terminal helix-turn-helix motif. rafO, as defined by in vivo titration of raf repressor, consists of two nearly identical 18-base-pair palindromes that flank the -35 box of the raf promoter.
