In a study on the sulfate-activating system of marine macroalgae, an interesting sulfate-containing nucleotide was found as the enzymatic reaction product, and was isolated by DEAE-Toyo Pearl column chromatography. This nucleotide showed an ultraviolet spectrum similar to that of IMP, and had an acid-labile phosphate-sulfate anhydride bond at the 5' position. It was identified as inosine-5'-phosphosulfate by comparison with a synthetic specimen. It was speculated that inosine-5'-phosphosulfate was formed from the active sulfate, adenosine-5'-phosphosulfate, by the enzymatic deamination.
