Using the local MEME program, we compared the amino acid sequence of the Chinese wheat mosaic virus coat protein to that of a large collection of glycosyl hydrolase-related sequences (bacterial glycosyl hydrolase, plant glycosyl hydrolase) obtained from the Uniprot database. According to Table , the entire coat protein region contains Glyco trans X, Glyco hydro X, and GH X series glycosyl hydrolase domains. Hydrolyzing different glycosyl chains is an indication that the coat protein has this activity.
