Regulation of the bacterial cell wall: analysis of a mutant of Bacillus subtilis defective in biosynthesis of teichoic acid.

abstract：:The nucleotide sequence of a 2.0-kilobase DNA segment containing the Clostridium acetobutylicum glnA gene was determined. The upstream region of the glnA gene contained two putative extended promoter consensus sequences (p1 and p2), characteristic of gram-positive bacteria. A third putative extended gram-positive prom...
