Study on inactivation of Tobacco mosaic virus by y3 from Mushroom (Coprinus comatus)
Abstract: A antiviral protein y3, from mushroom Coprinus comatus, could inactivate Tobacco mosaic virus (TMV) in vitro. The inhibition rate against is 50.0% when the concentration of y3 is 2.0μg/mL. When RNase was added to the mixture of TMV and y3, the infection rate of TMV was 61.74%, decreased by 38.26% in contrast with the control. It was also shown that y3 can break TMV particles when observed under electron microscope.
