The Sphingobium sp. strain SYK-6 genome contains three genes involved in salicylate catabolism: SLG_11260, SLG_11270, and SLG_11280. Here, we report that the gene product of SLG_11280 functions as a maleylpyruvate hydrolase (SsMPH) with Km and Kcat values of 166.2muM and 3.76 min(-1), respectively. This study also reveals the crystal structures of both the apo and pyruvate-manganese ion-bound SsMPH, which revealed that like other fumarylacetoacetate hydrolases, SsMPH dimerizes and has nine unique 310-helices. Molecular docking studies of maleylpyruvate also revealed the likely binding mode of SsMPH and its substrate. Structural insights into a maleylpyruvate hydrolase from sphingobium sp.
