FunctionPublication Abstract from PubMedInorganic pyrophosphatase (PPase) plays an essential role in energy conservation and provides energy for many biosynthetic pathways. Here, we present two three-dimensional structures of PPase from Homo sapiens (Hu-PPase) at 2.38 A and 3.40 A in different crystallization conditions. One of the Hu-PPase structures complex of two magnesium metal ions was determined to be a monomer (Hu-PPase-mono) here, while the other one to be a dimer-dimer (Hu-PPase-dd). In each asymmetric unit of Hu-PPase-mono, there are four alpha-helices and ten beta-strands and folds as a barrel structure, and the active site contains two magnesium ions. Like PPases from many species, we found that Hu-PPase was able to undergo self-assembly. To our surprise, disruption of the self-assembly of Hu-PPase did not influence its enzymatic activity or the ability to promote cell growth. Our work uncovered that different structure forms of Hu-PPase and found that the pyrophosphatase activity of Hu-PPase is independent of its self-assembly.
