Enzymatic sulfation of phenolic hydroxy groups of various plant metabolites by an arylsulfotransferase
The bacterial arylsulfate sulfotransferase (AST) from Desulfitobacterium hafniense was used as a catalytic tool to derivatize poorly soluble aromatic compounds (polyphenols). As examples, we sulfated the natural occurring compounds p-coumaric acid, 6-hydroxyflavone, resveratrol, phloretin, and quercetin, using p-nitrophenylsulfate as the sulfate donor. The water-soluble sulfate esters were purified and characterized. Depending on the nature of the compound, one or more sulfate groups could be introduced in a stepwise order. The sulfation of resveratrol resulted in two different monosulfates (4′- and 3-sulfates), the 3,4′-disulfate, and the 3,5,4′-trisulfate. Sulfation of phloretin resulted in a monosulfate (4′-sulfate) and a disulfate (4,4′-disulfate). Although quercetin has five hydroxy groups that could be sulfated, surprisingly this enzyme system primarily catalyses the sulfation only at the 4′ position. This simple enzymatic one-step sulfation method is easy to use, and it allows a convenient and simple production of sulfated compounds with improved solubility.
