Comment | Members of this protein family are bacterial, phosphatidylcholine-hydrolyzing phospholipase C enzymes, with a characteristic domain architecture as found in hemolytyic (PlcH) and nonhemolytic (PlcN) secreted enzymes of Pseudomonas aeruginosa. PlcH hydrolyzes phosphatidylcholine to diacylglycerol and phosphocholine, but unlike PlcN can also hydrolyze sphingomyelin to ceramide ((N-acylsphingosine)) and phosphocholine. Members of this family share the twin-arginine signal sequence for Sec-independent transport across the plasma membrane. PlcH is secreted as a heterodimer with a small chaperone, PlcR, encoded immediately downstream. |
