was considered in this study uses thioredoxin dependent adenylyl-sulfate reductase catalyzes the conversion of 5'-adenosinephosphosulfate into 5′-phosphosulfate. The 5'-phosphosulfate is then changed into 3′-phosphoadenosine 5′-phosphate and sulfite similarly to the general pathway that is a result of the combined products mentioned in the general reaction of adenylyl-sulfate reductase, regardless of the electron donor used. The resulting sulfite post-reaction is commonly used in Cysteine/Methionine production within cells utilizing this enzyme. References Further reading EC 1.8.4 Enzymes of known structure
