PEREZ, Aurora T. et al. Proteolytic activity of enzymatic extracts from plants of the Bromeliaceae family. Rev Cubana Plant Med [online]. 2006, vol.11, n.2. ISSN 1028-4796.

The proteolytic enzymes isolated from the Bromeliaceae family are widely used in the medical, biotechnological, and food industries. The studies conducted in recent years on the activity against metastasis and cysteine-proteases, increase the interest in screening new natural sources of obtention of phytoproteases. In the present paper, the authors assessed the proteolytic activity of enzymatic extracts obtained from different organs of the Bromeliaceae family plants. Five groups were collected and classified. Plants obtained belong to three genuses of the above mentioned family: 3 groups are of genus Tillandsia , one of genus Guzmania , and the other of genus Hohenbergia . The highest rates of specific activity (3.3 U/mg of proteins) were attained in preparations obtained from different organs of Hohenbergia penduliflora Mez. from whose extracts the influence of extraction pH was assessed. The specific activity was greater on carrying it out at pH3, starting from their stalks.
