title: Improved synthesis and rapid isolation millimole quantities of adenylysulfate.
abstract: An improved enzymatic method for the synthesis of adenylysulfate (APS) from adenosine 5'-phosphate using APS-reductase from Thiobacillus denitrificans is described. Isolation of millimole quantitities of this sulfur nucleotide is achieved rapidly by means of ion exchange chromatography on a strongly basic ion exchange resin. A facile and reproducible desalting procedure is described.
