ATP adenylyltransferase C-terminal domain
Members of this family of proteins catabolise Ap4N nucleotides (where N is A,C,G or U). Additionally they catalyze the conversion of adenosine-5-phosphosulfate (AMPs) plus Pi to ADP plus sulphate, the exchange of NDP and phosphate and the synthesis of Ap4A from AMPs plus ATP.
