FunctionAP4A_HUMAN Asymmetrically hydrolyzes Ap4A to yield AMP and ATP. Plays a major role in maintaining homeostasis. Publication Abstract from PubMedApA hydrolase (asymmetrical diadenosine tetraphosphate hydrolase, EC 3.6.1.17), an enzyme involved in a number of biological processes, is characterized as cleaving the polyphosphate chain at the fourth phosphate from the bound adenosine moiety. This paper presents the crystal structure of wild-type and E58A mutant human ApA hydrolase. Similar to the canonical Nudix fold, human ApA hydrolase shows the common alphabetaalpha-sandwich architecture. Interestingly, two sulfate ions and one diphosphate coordinated with some conserved residues were observed in the active cleft, which affords a better understanding of a possible mode of substrate binding. Crystal structure of wild-type and mutant human Ap4A hydrolase.,Ge H, Chen X, Yang W, Niu L, Teng M Biochem Biophys Res Commun. 2013 Mar 1;432(1):16-21. doi:, 10.1016/j.bbrc.2013.01.095. Epub 2013 Feb 4. PMID:23384440[1] From MEDLINE®/PubMed®, a database of the U.S. National Library of Medicine. References
