E. coli strain JA200 carrying plasmid pPS3155-lambda (JA200/pPS3155-A)

Description:

E. coli Strain JA200 Carrying Plasmid pPS3155-lambda

The Technology: Dr. William Dowhan at the University of Texas Health Science Center at Houston (UTHealth) 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. This bacterial strain lacks phosphatidylethanolamine (PE) and contains monoglucosyldiacylglycerol. At present, the role of individual phospholipids in specific membrane functions is not completely understood. Mutants with defects in the biosynthesis of particular classes of phospholipids provide a powerful tool to study different membrane associated processes and specifically the involvement of phospholipids in protein translocation across membranes
