    Protein Summary

    The Npun_F1925 gene from Nostoc punctiforme pcc 73102 codifies for a DOPA dioxygenase-like protein. The structure solved here corresponds to sequence YP_001865521 with the point mutations E103A, Q104A and D106A. It belongs to the DOPA 4,5-dioxygenase family (PF08883). In its genome vicinity, with a STRING score 0.766, sits a D-lactose dehydrogenase (NP_484102).


    SCOP classifies 2peb in the alpha+beta class, ferredoxin-like fold, DOPA-like superfamily, DOPA dioxygenase-like family. 2peb chelates a Zn ion per molecule via the conserved side chains of residues H12, H14, H84 and an unknown compound; it is highly similar in terms of tertiary structure to 2p8i (SSM 80%; Dali Z-scr=20) and 2nyh (SSM 80%; Dali Z-scr=19.6).
