    Protein Summary

    The tenA-1 (SSO2206) gene from S. solfataricus encodes the NP_343586.1 sequence that belongs to the transcriptional activator tenA/thiamine biosynthesis THI-4 family (PF03070). Based on gene fusion and co-ocurrence events, STRING provides a 0.84 hit with thiD-1 phosphomethyl pyrimidine kinase (NP_341579). 


    SCOP classifies 2qzc in the all-alpha class, heme oxygenase-like superfamily, TENA/THI-4 family. The crystal structure contains a molecule of imidazole per chain chelated by residues D47 and E198. High structural similarity (FFAS scr=-87; SSM 89%; Dali Z-scr=25; FATCAT P-val=5e-15) is observed with PDB:1udd [Ref], and PDB:2gm8, both TenA homologues.
