Effects of adenine nucleotides on rice-root adenosine triphosphate sulphurylase activity in vitro

The presence of ATP sulphurylase activity in the 30000g supernatant fraction of rice-root homogenate has been demonstrated. Studies of the effects of adenosine and its nucleotides on the enzymic activity showed that AMP activated but that ADP and adenosine inhibited the enzyme.
