Studies on the biosynthesis of acylphosphatidylglycerol in Escherichia coli B and B/r.
The present study has demonstrated that one molecule of acylphosphatidylglycerol was synthesized from two molecules of phosphatidylgycerol by the transacylation reaction in which phosphatidylglycerol acted both as an acyl donor and an acceptor. Phosphatidylethanolamine was identified as an another acyl donor, participating in acylphosphatidylglycerol formation. These results are discussed in terms of a new pathway for the turnover of phosphatidylglycerol in Escherichia coli.
