Identification of the gene (aphA) encoding the class B acid phosphatase/phosphotransferase of Escherichia coli MG1655 and characterization of its product.

An open reading frame located in the tyrB-uvrA intergenic region of the Escherichia coli MG1655 chromosome was identified as encoding the class B acid phosphatase of this species on the basis of cloning and expression experiments. A protocol for purification of the enzyme (named AphA) was developed, and its properties were analyzed. The enzyme is a 100-kDa homotetrameric protein which apparently requires a metal co-factor for activity. Similarly to other bacterial class B acid phosphatases, it is able to dephosphorylate several organic phosphomonoesters as well as to catalyze the transfer of low-energy phosphate groups from phosphomonoesters to hydroxyl groups of various organic compounds. << Less

Haloacid dehalogenase (HAD)-like hydrolases are a vast superfamily of largely uncharacterized enzymes, with a few members shown to possess phosphatase, beta-phosphoglucomutase, phosphonatase, and dehalogenase activities. Using a representative set of 80 phosphorylated substrates, we characterized the substrate specificities of 23 soluble HADs encoded in the Escherichia coli genome. We identified small molecule phosphatase activity in 21 HADs and beta-phosphoglucomutase activity in one protein. The E. coli HAD phosphatases show high catalytic efficiency and affinity to a wide range of phosphorylated metabolites that are intermediates of various metabolic reactions. Rather than following the classical "one enzyme-one substrate" model, most of the E. coli HADs show remarkably broad and overlapping substrate spectra. At least 12 reactions catalyzed by HADs currently have no EC numbers assigned in Enzyme Nomenclature. Surprisingly, most HADs hydrolyzed small phosphodonors (acetyl phosphate, carbamoyl phosphate, and phosphoramidate), which also serve as substrates for autophosphorylation of the receiver domains of the two-component signal transduction systems. The physiological relevance of the phosphatase activity with the preferred substrate was validated in vivo for one of the HADs, YniC. Many of the secondary activities of HADs might have no immediate physiological function but could comprise a reservoir for evolution of novel phosphatases. << Less
