1. Comparison of amino acid regions forming [4Fe-4S] clusters in the SplB amino acid sequences from Bacillus anthracis (B.an), B. amyloliquefaciens (B.am), B. stearothermophilus (B.st), B. subtilis (B.su),Clostridium acetobutylicum (C.ac), and C. difficile (C.di) with the [4Fe-4S] clusters of: the activating subunits of ribonucleotide reductase (NrdG) and pyruvate-formate lyase (Act) from Escherichia coli (E.co), phage T4 (T4), andHaemophilus influenzae (H.in) and the [4Fe-4S] clusters from lysine-2,3-aminomutase (KamA) from Clostridium subterminale (C.su), biotin synthase (BioB) from B. subtilis, and the probable lipoic acid synthase (YutB) fromB. subtilis.
