Sequence analysis showed that the full-length cDNA sequence of Sc-SAMDC (GenBank Accession number: GQ246459) was 1 968 bp, with three open reading frames, tiny ORF, upstream ORF and main ORF. The mORF was 1200 bp encoding 399 amino acid residues with a molecular mass of 43.6 kD, and the deduced protein had two highly conserved function domains (proenzyme cleavage site and PEST domain).
