英文摘要
We have recently identified PGAM5 as a novel type of protein phosphatase that relies on a histidine residue as a catalytic center; however, its mechanism of enzymatic action has not been revealed. In the current study, we found by structural analyses that the catalytic center of PGAM5 consists of two histidines and two arginines. We also found that PGAM5 forms a dimer and that the dimerization is required for the catalytic activity of PGAM5. These results provide important clues to the mechanism of action of the histidine-based protein phosphatases.
