Furthermore, it is found that in the presence of p-bromophenacyl bromide (p-BPB), there is a significant decrease in enzymatic activity and associated antibacterial activities, suggesting that a strong association exists between catalytic activity and antimicrobial effects, which thereby destabilize the membrane bilayer.These studies encourage further in dept study on molecular mechanisms of bactericidal properties of NN-XIb-PLA2 and thereby help in development of this protein into a possible therapeutic lead molecule for treating bacterial infections. Here, PLA2G2A is linked to bacterial infectious disease.
