    ..Our findings reveal that S-sulfocysteine and the activity of S-sulfocysteine synthase play important roles in chloroplast function and are essential for light-dependent redox regulation within the chloroplast. ..

    ..In this study, we have cloned, expressed and characterised a cysteine desulphurase (SufS) from Haloferax volcanii and demonstrated that this protein is able to reconstitute the [Fe-S] cluster of halophilic ferredoxin...
