PAPs are found in plants, animals and fungi; in humans they play an important role in bone turnover and are thus of interest for developing treatments for osteoporosis. The majority of metallohydrolases use a metal-bound hydroxide to initiate catalysis, which leads to the formation of a proposed five-coordinate oxyphosphorane species in the transition state. In this work, we crystallized PAP from red kidney beans (rkbPAP) in the presence of both adenosine and vanadate. The in crystallo-formed vanadate analogue of ADP provides detailed insight into the binding mode of a PAP substrate, captured in a structure that mimics the putative fivecoordinate transition state. Our observations not only provide unprecedented insight into the mechanism of metallohydrolases, but might also guide the structure-based design of inhibitors for application in the treatment of several human illnesses. The Binding Mode of an ADP Analogue to a Metallohydrolase Mimics the Likely Transition State.,Feder D, Gahan LR, McGeary RP, Guddat LW, Schenk G Chembiochem. 2019 Feb 4. doi: 10.1002/cbic.201900077.
