HHsearch alignment for GI: 254780911 and conserved domain: cd04903
>cd04903 ACT_LSD C-terminal ACT domain of the L-serine dehydratase (LSD), iron-sulfur-dependent, beta subunit. The C-terminal ACT domain of the L-serine dehydratase (LSD), iron-sulfur-dependent, beta subunit, found in various bacterial anaerobes such as Clostridium, Bacillis, and Treponema species. These enzymes catalyze the deamination of L-serine, producing pyruvate and ammonia. Unlike the eukaryotic L-serine dehydratase, which requires the pyridoxal-5'-phosphate (PLP) cofactor, the prokaryotic L-serine dehydratase contains an [4Fe-4S] cluster instead of a PLP active site. The LSD alpha and beta subunits of the 'clostridial' enzyme are encoded by the sdhA and sdhB genes. The single subunit bacterial homologs of L-serine dehydratase (LSD1, LSD2, TdcG) present in Escherichia coli, and other enterobacterials, lack the ACT domain described here. Members of this CD belong to the superfamily of ACT regulatory domains.
