    Protein Summary

    The Sfri_1312 gene from Shewanella frigidimarina ncimb 400 encodes a tryptophan halogenase (PF04820) that shows strong sequence and structural similarity to a tryptophan 5-halogenase from Streptomyces rugosporus (PDB id: 2WES, DALI Z-score 46.2, rmsd 2.0 Å over 485 residues, identity 32%), suggesting this is also the specificity of Sfri_1312 (EC 1.33.99.B1). For more information on the structure and function of this protein see [Ref].


    To do: Confirm specificity by comparing FAD/catalytic site/residues; is Sfri_1312 also a tetramer?
