Bacterial phospholipases. Legionella pneumophila possesses a major cell-associated hemolytic phospholipase A (PlaB) which shares no homology to described phospholipases. PlaB preferentially hydrolyzes long-chain fatty acid substrates containing 12 or more carbon atoms. PlaB shows concentration-dependent phospholipase inactivation by tetramerization which may be a mechanism for self-protection. See Papers: Bender et al. 2009 and Kuhle et al. 2014. The tetramer is a dimer of identical dimers. Diwo et al. found in the structure eight NAD(H) molecules at the dimer/dimerinterface, suggesting that these molecules stabilize the tetramer leading to enzyme inactivation.
