    Organism
    Escherichia coli str. K-12 substr. MG1655 (strain: K-12, substrain: MG1655)
    Lineage
    Bacteria; Pseudomonadota; Gammaproteobacteria; Enterobacterales; Enterobacteriaceae; Escherichia
    Also known as
    ECK1273
    Summary
    The pgpB gene is nonessential, but is synthetically lethal with a bacA ybjG double mutant, due to its UppP activity. ybjG, pgpB, and lpxT are paralogs. [More information is available at EcoGene: EG10705]. PgpB is one of three phosphatidylglycerophosphatase (PGP-ase) activities in Escherichia coli. [More information is available at EcoCyc: EG10705].
