Inhibitory mechanism of lactoferrin on antibacterial activity of oenothein B: isothermal titration calorimetry and computational docking simulation

Journal of the Science of Food and Agriculture, 2020
AbstractBACKGROUNDMany foods contain proteins and polyphenols, but there is a poor understanding of the nature of the inhibitory effect of protein on the biologic activity of polyphenols. The inhibitory mechanism of the food protein lactoferrin on the antibacterial activity of oligomeric ellagitannin oenothein B (OeB) was investigated using ...
