Abstract excerpt
The dgkB gene is essential for the growth of Bacillus subtilis. It encodes a diacylglycerol (DG) kinase that converts DG to phosphatidic acid to reintroduce it into the phospholipid synthesis pathway. Repression of the dgkB gene placed under a regulatable promoter causes accumulation of DG and leads to lethality. DG is formed as a byproduct of the synthesis of lipoteichoic acid (LTA), a polyanionic component of...
