Abstract
An antiviral protein (AAP29) with ribosome-inactivating activity was purified and characterized from the leaves of the Amaranthus mangostanus. Purification was accomplished through crude extraction, ammonium sulfate precipitation, S-Sepharose chromatography, gel filtration, CM-Sepharose chromatography and Blue sepharose chromatography. This protein was about 29.2 kDa and strongly basic with the PI value between 9.0 and 9.6, indicating that AAP29 is similar to Type 1 RIP. The AAP29 showed high thermostability without activity toss even after 20 min at
참비름 (Amaranthus mangostanus) 잎에서 단백질을 추출하여 S-Sepharose, Sephacryl S-200 HR, CM-Sepharose, Blue sepharose column chromatography에 의하여 단백질 합성 저해능이 있는 항바이러스성 단백질 (Amarnanthus antiviral protein, AAP29)을 분리하였다. 정제된 단백질의 분자량은 SDS-PAGE에서 약 29,200이었으며, 등전점은 9.0
