Antibiotic production by myxobacteria plays a role in predation.

abstract：:Phosphatidylglycerol, the most abundant acidic phospholipid in Escherichia coli, is considered to play specific roles in various cellular processes that are essential for cell viability. A null mutation of pgsA, which encodes phosphatidylglycerophosphate synthase, does indeed confer lethality. However, pgsA null mutan...
