The xyl operator of Bacillus subtilis W23 was identified by deletion analysis of the xyl regulatory region as a 25-base-pair (bp) sequence located 10 bp downstream from the xyl promoter. The outer 10 bp of the xyl operator exhibit perfect palindromic symmetry, while 5 central bp are nonpalindromic. It was demonstrated that the penultimate base pair near the end of this sequence is important for repressor binding. The location of the xylR gene encoding the repressor was determined by its ability to mediate xylose-dependent repression of a xyl-cat fusion on a multicopy plasmid. The nucleotide sequence of 1,355 bp from this DNA was analyzed and contains an open reading frame with a coding capacity for 384 amino acids leading to a protein with a calculated molecular weight of 42,270. A mutant with a deletion in this reading frame showed no repression of the xyl-cat fusion. The coding sequence is preceded by a suitable ribosome-binding sequence and uses GTG as a start codon and TAA as a stop codon. The relationship of these results to corresponding data obtained from B. subtilis 168 is discussed.
