Reported here are three synthetic nickel pincer complexes that are both structural and functional models of the pincer cofactor in lactate racemase. DFT computations suggest the ipso-carbon atom of the pyridinium pincer ligands act as a hydride acceptor for lactate isomerization, whereas an organometallic pathway involving nickel-mediated beta-hydride elimination is less favored.Chemistry, MultidisciplinaryChemistrycofactorsenzymesnickelpincer ligandsreaction mechanismsdensity functionalsactive-sitecomplexhydrosilylationcatalysisbondFunctional Models of the Nickel Pincer Nucleotide Cofactor of Lactate Racemasetext::journal::journal article::research article
