    Protein Summary

    Gene Npun_R0239 from Nostoc punctiforme pcc 73102 encodes the YP_001863968 that belongs to the O-methyltransferase 2 group (PF00891).

    Pre-SCOP classifies the N-terminal domain (1-87) in the all alpha class, winged-helix DNA binding domain superfamily; the C-terminal domain (90-333) belongs to the alpha/beta class, S-adenosyl-L-methionine dependent methyltransferases superfamily. According to DALI, 2r3s shows structural similarity to several methyl-transferases (PDB codes: 1tw3 [Z=30], 3i5u [Z=29], 1fpx [Z=28], 2ip2 [Z=26], 1kyz [Z=25]).  In contrast to the glycine rich motif (DxGxG) present in similar methyltransferases, 2r3s has the "DISAS" sequence motif. 2r3s crystallizes as an homodimer.
