    Protein Summary

    The TM1828 from T. maritima - is a bifunctional protein found in bacteria and archaea. Its N-terminal part contains riboflavin-specific deaminase (cd01284), while  C-terminal part contains pyrimidine reductase (COG1985, ribD).

    TM1828 functions are interdependent with the folowing genomic neighbors having similar phylogenetic cooccurrence: TM1827 [Q9X2E7] - riboflavin synthase, alpha subunit; RIBH [RISB_THEMA] - 6,7-dimethyl-8-ribityllumazine synthase (EC; RIBA [GCH2_THEMA] - riboflavin biosynthesis protein ribA.

    TM1828 has strong structural similarity to: PDB:2b3z (DALI Z-score 38.8; RMSD 2.2; 40% identity within 337 superimposed residues), PDB:1d1g (DALI Z-score 17.0; RMSD 2.4; 22% identity within 156 superimposed residues), PDB:1uaq (DALI Z-score 15.5; RMSD 2.5; 29% identity within 126 superimposed residues), PDB:2g84 (DALI Z-score 15.2; RMSD 2.6; 29% identity within 119 superimposed residues), PDB:1teo (DALI Z-score 15.0; RMSD 1.9 ; 35% identity within 116 superimposed residues).

    Analysis of the crystallographic packing of TM1828 using the PQS server {Henrick, 1998 #73} indicates that a dimer is the biologically relevant form.
