    Protein Summary

    The Npun_F6505 gene from Nostoc punctiforme pcc 73102 encodes the NP_001869710 protein of unknown function and adopts a heme oxygenase-like fold. HHPred strongly predicts homology with the TENA/THI-4/PQQC family (PF03070, P-value3.8E-21, residues 22-226), a prediction also supported by structural similarity (PDB id: 1RCW, FATCAT P-value 2.78e-12, DALI Z-score 18.0). The similarity with PDB id 1RCW suggests a role in host cell apoptosis modulation [Ref]


    To do: compare 1RCW di-iron center/coordinating residues/death domain interacting surface with Npun_F6505.
