Sequence analysis, multiple templates structure prediction and binding site identification of bromelain from ananas comosus
Bromelain is a proteolytic enzyme derived from pineapples and categorized as a cysteine protease. This enzyme is widely used as an anti-inflammatory agent in therapeutic applications. In this study, the molecular interactions of bromelain against phospholipase A2 (Pla2), a target protein in inflamma...
