Bacterial Strain (AD93/pDD72) with Altered Phospholipid Composition for the Production Cardiolipin

Description:

Bacterial Strain with Altered Phospholipid Composition for the Production of Cardiolipin

The Technology: Dr. William Dowhan at the University of Texas Health Science Center at Houston (UTHSC-H) has developed a bacterial strain to construct null mutants in specific steps of phospholipid biosynthesis. The anionic phospholipid (phosphatidylglycerol and cardiolipin) content of the mitochondria can be varied and controlled in these mutants. Cardiolipin is an essential lipid of the mitochondria and until recently has been understudied as to function and regulation of synthesis because of the lack of mutants and cloned genes.
