May be a sulfotransferase involved in the transport of sulfate. Displays very low rhodanese activity. hydrogen cyanide + thiosulfate = 2 H(+) + sulfite + thiocyanate By sulfur deprivation. Contains two rhodanese domains with different primary structures but with near identical secondary structure conformations suggesting a common evolutionary origin. Only the C-terminal rhodanese domain contains the catalytic cysteine residue (By similarity).
