O-phospho-L-seryl-tRNA:Cys-tRNA synthase

O-phospho-L-seryl-tRNA:Cys-tRNA synthase (, SepCysS, Sep-tRNA:Cys-tRNA synthase) is an enzyme with systematic name O-phospho-L-seryl-tRNACys:hydrogen sulfide 2-aminopropanoate transferase. This enzyme catalyses the following chemical reaction


 * O-phospho-L-seryl-tRNACys + sulfide $$\rightleftharpoons$$ L-cysteinyl-tRNACys + phosphate
