Percent identity shared between the Rr-ENG-1 catalytic domain and the catalytic domains of other selected cellulases. Percent shared identity was determined using CLUSTALW. Gr (Globodera rostochiensis), Gt (G. tabacum), Hg (Heterodera glycines), Hs (H. schachtii), Rs (Radopholus similis), Dd (Ditylenchus destructor), Da (D. africanus), Mi (Meloidogyne incognita), Pp (Pratylenchus penetrans).
