ABSTRACT
Figure 9.1 Complementary catalytic reactions controlled by STs and sulfatases. STs transfer a sulfuryl group (boxed) from the abundant, high-energy, sulfuryl donor PAPS to an awaiting oxygen or nitrogen acceptor, producing a sulfated biomolecule and the byproduct, PAP. Sulfatases catalyze the hydrolytic desulfurylation of sulfates (CO-SO3-) and sulfamates (CN-SO3-), generating a desulfurylated substrate and inorganic sulfate.
