Function

SUFS_BACSU Enzyme able to deliver sulfur to partners involved in Fe-S cluster assembly. Catalyzes the removal of elemental sulfur atoms from L-cysteine to produce L-alanine. Activity is stimulated 40-to 100-fold by SufU, which acts as a second substrate for this enzyme following release of Ala, and generating SufU.S. A mixture of SufS, SufU, Fra and L-cysteine is able to reconstitute Fe-S clusters on apo-aconitase (citB), reconstituting aconitase activity.[1] [2] [3]
