Secondary Information

Protein Function involved in mitochondrial biogenesis and bioenergetics via CysSSH(Cysteine hydropersulfide) production,which are essential structural components of several proteins and enzymes, e.g. serving as metal ligands in iron-sulfur clusters (or sulfide donors) and in iron-cysteine and zinc-cysteine complex.
Biochemical Properties  Binds 1 zinc ion per subunit.Recognizes tRNA-Cys and utilizes ATP as cofactor and L-Cysteine as substrate to form L-cysteinyl-tRNA-Cys.
