  Structural Determinants of Substrate Recognition in the HAD Superfamily Member d-glycero-d-manno-Heptose-1,7-bisphosphate Phosphatase (GmhB),

  摘要：

  The haloalkanoic acid dehalogenase (HAD) enzyme superfamily is the largest family of phosphohydrolases. In HAD members, the structural elements that provide the binding interactions that support substrate specificity are separated from those that orchestrate catalysis. For most HAD phosphatases, a cap domain functions in substrate recognition. However, for the HAD phosphatases that lack a cap domain, an alternate strategy for substrate selection must be operative. One such HAD phosphatase, GmhB of the HisB Subfamily, was selected for structure-function. analysis. Herein, the X-ray crystallographic structures of Escherichia coli GmhB in the apo form (1.6 angstrom resolution), in a complex with Mg2+ and orthophosphate (1.8 angstrom resolution), and in a complex with Mg2+ and D-glycero-D-manno-heptose 1 beta,7-bisphosphate (2.2 angstrom resolution) were determined, in addition to the Structure of Bordetella bronchiseptica GmhB bound to Mg2+ and orthophosphate (1.7 angstrom resolution). The Structures show that in place of a cap domain, the GmhB catalytic site is elaborated by three peptide inserts or loops that pack to form a concave, semicircular surface around the substrate leaving group. Structure-guided kinetic analysis of site-directed mutants was conducted in parallel with a bioinformatics study of sequence diversification within (lie HisB subfamily to identify loop residues that serve as substrate recognition elements and that distinguish GmhB from its subfamily counterpart, the histidinol-phosphate phosphatase domain of HisB. We show that GmhB and the histidinol-phosphate phosphatase domain use the same design of three Substrate recognition loops inserted into the cap domain yet, through selective residue usage on the loops, have achieved unique substrate specificity and thus novel biochemical function.

  Towards Gram-negative antivirulence drugs: New inhibitors of HldE kinase

  摘要：

  Gram-negative bacteria lacking heptoses in their lipopolysaccharide (LPS) display attenuated virulence and increased sensitivity to human serum and to some antibiotics. Thus inhibition of bacterial heptose synthesis represents an attractive target for the development of new antibacterial agents. HldE is a bifunctional enzyme involved in the synthesis of bacterial heptoses. Development of a biochemical assay suitable for high-throughput screening allowed the discovery of inhibitors 1 and 2 of HldE kinase. Study of the structure-activity relationship of this series of inhibitors led to highly potent compounds. (c) 2008 Elsevier Ltd. All rights reserved.

  D-glycero-D-manno-Heptose-1,7-bisphosphate phosphatase (GmhB) is a member of the histidinol-phosphate phosphatase (HisB) subfamily of the haloalkanoic acid dehalogenase (HAD) enzyme superfamily. GmhB supports two divergent biochemical pathways in bacteria: the D-glycero-D-manno-heptose-1 alpha-GDP pathway (in S-layer glycoprotein biosynthesis) and the L-glycero-D-manno-heptose-1 beta-ADP pathway (in lipid A biosynthesis). Herein, we report the comparative analysis Of Substrate recognition in selected GmhB orthologs. The substrate specificity of the L-glycero-D-manno-heptose-1 beta-ADP pathway GmhB from Escherichia coli K-12 was evaluated using hexose and heptose bisphosphates, histidinol phosphate, and common organophosphate metabolites. Only D-glycero-D-manno-heptose 1 beta,7-bisphosphate (k(cat)/k(m) = 7 x 10(6) M-1 s(-1)) and D-glycero-D-manno-heptose 1 alpha,7-bisphosphate (k(cat)/K-m, = 7 x 10(4) M-1 s(-1)) displayed physiologically significant Substrate activity. P-31 NMR analysis demonstrated that E. coli GmhB selectively removes the C(7) phosphate. Steady-state kinetic inhibition studies showed that D-glycero-D-manno-heptose 1 beta-phosphate (K-is = 60 mu M, and K-ii = 150 mu M) and histidinol phosphate (K-is = 1 mM, and K-ii = 6 mM), while not hydrolyzed, do in fact bind to E. coli GmhB, which leads to the conclusion that nonproductive binding contributes to substrate discrimination. High catalytic efficiency and a narrow substrate range are characteristic of a well-evolved metabolic enzyme, and as such, E. coli GmhB is set apart from most HAD phosphatases (which are typically inefficient and promiscuous). The specialization of the biochemical function of GmhB was examined by measuring the kinetic constants for hydrolysis of the alpha- and beta-anomers of D-glycero-D-manno-heptose 1 beta,7-bisphosphate catalyzed by the GmhB orthologs of the L-glycero-D-manno- 1 beta-ADP pathways operative in Bordetella bronchiseptica and Mesorhizobium and by the GmhB of the D-glycero-D-manno-heptose 1 alpha-GDP pathway operative in Bacteroides thetaiotaomicron. The results show that although each of these representatives possesses physiologically significant catalytic activity toward both anomers, each displays substantial anomeric specificity. Like E. coli GmhB, B. bronchiseptica GmhB and M. loti GmhB prefer the beta-anomer, whereas B. thetaiotaomicron GmhB is selective for the alpha-anomer. By determining the anomeric configuration of the physiological Substrate (D-glycero-D-manno-heptose 1,7- for each of the four GmhB orthologs, we discovered that the anomeric specificity of GmhB correlates with that of the pathway kinase. The conclusion drawn from this finding is that the evolution of the ancestor to GmhB in the HisB subfamily provided for specialization toward two distinct biochemical functions.

  An efficient one-pot three enzymes strategy for chemoenzymatic synthesis of ADP-D-glycero-beta-D-mannoheptose (ADP-D, D-heptose) was reported using chemically synthesized D, D-heptose-7-phosphate and the ADP-D, D-heptose biosynthetic enzymes HldE and GmhB. Moreover, the result of investigating substrate specificity of the kinase action of HldE revealed that HldE had highly restricted substrate specificity towards structurally modified heptose-7-phosphate analogs.
