Enzymes

General function:
Involved in ATP adenylyltransferase activity
Specific function:
Ap4A phosphorylase catabolizes Ap4N nucleotides (where N is A,C,G or U). Additionally this enzyme catalyzes the conversion of adenosine-5-phosphosulfate (AMPs) plus Pi to ADP plus sulfate, the exchange of NDP and phosphate and the synthesis of Ap4A from AMPs plus ATP
Gene Name:
APA1
Uniprot ID:
P16550
Molecular weight:
36492.19922
Reactions
ADP + ATP → phosphate + P(1),P(4)-bis(5'-adenosyl) tetraphosphate.
ADP + sulfate → phosphate + adenylyl sulfate.
Adenylylsulfate + ATP → P(1),P(4)-bis(5'-adenosyl)tetraphosphate + sulfate.
General function:
Involved in ATP adenylyltransferase activity
Specific function:
Sustains the catabolism of Np-4-N' nucleotides, rather than their synthesis
