Sulfotransferases are the first enzymes of the core sulfation pathways, they transfer sulfate from PAPS to the hydroxyl or amino group of a wide variety of acceptors, as given below

a. Molecular basis of symbiotic host specificity in Rhizobium meliloti: nodH and nodPQ genes encode the sulfation of lipochito-oligosaccharide signals

b. Sulfation of the choriogonadotropin alpha subunit in human placental explants

c. Tyrosine sulfation of the amino terminus of CCR5 facilitates HIV-1 entry

d. A tyrosine-sulfated peptide based on the N terminus of CCR5 interacts with a CD4-enhanced epitope of the HIV-1 gp120 envelope glycoprotein and inhibits HIV-1 entry.

e. The Xanthomonas oryzae pv. oryzae raxP and raxQ genes encode an ATP sulfurylase and APS kinase that are required for AvrXa21 avirulence.
