CHITINASE B FROM SERRATIA MARCESCENS IN COMPLEX WITH INHIBITOR PSAMMAPLIN
Overview
Several brominated tyrosine derived compounds, psammaplins A (1), K (2), and L (3) as well as bisaprasin (4) were isolated from the Fijian marine, sponge Aplysinella rhax during a bioassay guided isolation protocol. Their, structures were determined using NMR and MS techniques. Psammaplin A was, found to moderately inhibit chitinase B from Serratia marcescens, the mode, of inhibition being non-competitive. Crystallographic studies suggest that, a disordered psammaplin A molecule is bound near the active site., Interestingly, psammaplin A was found to be a potent antifungal agent.
