abstract：:The noncapsid protein expressed from ORF-206 of turnip yellow mosaic virus (TYMV) is autocatalytically processed by a papain-like protease, producing N-terminal 150-kDa and C-terminal 70-kDa proteins. By introducing two methionine residues near the N-terminus of the 70-kDa protein, we have obtained N-terminal amino ac...
