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/dimer interface, suggesting that these molecules stabilize the tetramer leading to enzyme inactivation
