CDP-DAG is converted to PGP by PGS1

At the inner mitochondrial (IM) membrane, CDP-diacylglycerol--glycerol-3-phosphate 3-phosphatidyltransferase (PGS1) converts cytidine diphosphate-diacylglycerol (CDP-DAG) and glycerol-3-phosphate (G3P) to phosphatidylglycerophosphate (PGP) and cytidine monophosphate (CMP). This event is inferred from rats. The enzyme PGS1 has been characterized in humans (Ota et al. 2004).

在细胞线粒体内部膜中，CDP-二酰甘油-甘油-3-磷酸3-磷酸酰基转移酶（PGS1）将胞苷二磷酸二酰甘油（CDP-DAG）和甘油-3-磷酸（G3P）转化为磷脂酰甘油磷酸（PGP）和胞苷单磷酸（CMP）。此过程根据对大鼠的研究进行推断。人类中的PGS1酶已被特征化，相关研究由Ota等人于2004年发表。
