This full-length cDNA sequence has 917 bp including 528 bp open reading frame encoding a protein of 175 amino acids, with a predicted molecular mass of 19.3 kD and pI of 9.32. OmE2 protein which had significant amino sequence identity and similarity with ubiquitin-conjugating enzyme from other species contained the conserved sequence and cysteine residue in active sites of ubiquitin-conjugating family. OmE2 had three trans-membrane domains. It is predicted that OmE2 protein is a kind of ubiquitin-conjugating protein and transmembrane protein. The expression of OmE2 inOryza meyeriana was induced by Xanthomonas campestris pv. oryzae. Therefore OmE2 gene which was first found in wild rice may participate in the signal transduction and the resistance response in Oryza meyeriana.
