Human Thiosulfate Sulfurtransferase, TST ELI

Formation of iron-sulfur complexes, cyanide detoxification or modification of sulfur-containing enzymes.

Other thiol compounds, besides cyanide, can act as sulfur ion acceptors.

Also has weak mercaptopyruvate sulfurtransferase (MST) activity (By similarity).

Together with MRPL18, acts as a mitochondrial import factor for the cytosolic 5S rRNA.

Only the nascent unfolded cytoplasmic form is able to bind to the 5S rRNA.
