초록
A class I type 2 metallothionein (CMet2) cDNA from taproot of Codonopsis lanceolata was isolated and characterized. A CMet2 cDNA was 572 nucleotides long and had an open reading frame of 234 bp with a deduced amino acid sequence of 78 residues (pI = 4.99). The deduced amino acid sequence of CMet2 matched to the previously reported type 2 metallothionein- like protein genes and showed 74% identity with that of G. max (BAD18377) and C. arietinum (CAA65009). Expression of CMet2 by the RT-PCR was increased at 1 hr after cadmium and hydrogen peroxide treatment, respectively.
