Osmotin from Calotropis procera latex: New insights into structure and antifungal properties

►In this study we reported new insights into structure and antifungal properties of a latex protein. ►The protein was highly stable and active regardless pH conditions. ►It interacted and induced permeabilization of negatively charged large unilamellar vesicles. ►It also induced the membrane permeabilization of spores and hyphae from Fusarium solani, allowing for propidium iodide uptake.
