Реферат: Hexameric inorganic pyrophosphatase of Escherichia coli contains about 1 mol/mol of ‘structural’ pyrophosphate, which survives gel nitration and prolonged incubation with Mg2+, does not exchange with medium phosphate and pyrophosphate but is removed with 0.8 M perchloric acid. The site of pyrophosphate binding seems to be another than the active site. An additional 0.9 mol of enzyme-bound pyrophosphate is formed in the presence of phosphate and Mg2+ but this pyrophosphate is in fast equilibrium with medium phosphate and appears to be bound to the active site.
