full knowledge of opine metallophore stereochemistry is important as it is likely to influence receptor recognition as well as the coordination geometry for metal complexes. This is especially important for pseudopaline, because it incorporates an extra carboxylate ligand fromx022-oxoglutarate. As both PaODH and SaODH belong to the (R)-opine producing structural class, it is oproposed that they produce (R)-opine metallophores. The opine dehydrogenase reaction is reversible only for the opine metallophore product with (R)-stereochemistry at carbon C2 of the alpha-keto acid (prochiral prior to catalysis). Kinetic analysis using stopped-flow spectrometry with (R)- or (S)-staphylopine and kinetic and structural analysis with (R)- and (S)-pseudopaline confirms catalysis in the reverse direction for only (R)-staphylopine and (R)-pseudopaline, verifying the stereochemistry of these two opine metallophores. No NADP+ reduction with (S)-pseudopaline. Structural analysis at 1.57-1.85 A resolution captures the hydrolysis of (R)-pseudopaline and allows identification of a binding pocket for the L-histidine moiety of pseudopaline formed through a repositioning of Phe340 and Tyr289 during the catalytic cycle. Transient-state kinetic analysis reveals an ordered release of NADP+ followed by staphylopine, with staphylopine release being the rate-limiting step in catalysis. PaODH binds (S)-pseudopaline in a noncatalytic complex, (S)-pseudopaline binds above the nicotinamide ring of NADP+, structure analysis of enzyme-bound substrates, and reaction mechanism, detailed overview. PaODH crystals catalyze the hydrolysis of (R)-pseudopaline

full knowledge of opine metallophore stereochemistry is important as it is likely to influence receptor recognition as well as the coordination geometry for metal complexes. This is especially important for pseudopaline, because it incorporates an extra carboxylate ligand fromx022-oxoglutarate. As both PaODH and SaODH belong to the (R)-opine producing structural class, it is oproposed that they produce (R)-opine metallophores. The opine dehydrogenase reaction is reversible only for the opine metallophore product with (R)-stereochemistry at carbon C2 of the alpha-keto acid (prochiral prior to catalysis). Kinetic analysis using stopped-flow spectrometry with (R)- or (S)-staphylopine and kinetic and structural analysis with (R)- and (S)-pseudopaline confirms catalysis in the reverse direction for only (R)-staphylopine and (R)-pseudopaline, verifying the stereochemistry of these two opine metallophores. No NADP+ reduction with (S)-pseudopaline. Structural analysis at 1.57-1.85 A resolution captures the hydrolysis of (R)-pseudopaline and allows identification of a binding pocket for the L-histidine moiety of pseudopaline formed through a repositioning of Phe340 and Tyr289 during the catalytic cycle. Transient-state kinetic analysis reveals an ordered release of NADP+ followed by staphylopine, with staphylopine release being the rate-limiting step in catalysis. PaODH binds (S)-pseudopaline in a noncatalytic complex, (S)-pseudopaline binds above the nicotinamide ring of NADP+, structure analysis of enzyme-bound substrates, and reaction mechanism, detailed overview. PaODH crystals catalyze the hydrolysis of (R)-pseudopaline

opine dehydrogenases (ODHs) from the bacterial pathogens, e.g. Staphylococcus aureus, Pseudomonas aeruginosa, and Yersinia pestis, perform the final enzymatic step in the biosynthesis of the class of opine metallophores, which includes staphylopine, pseudopaline, and yersinopine, respectively. Comparison of structure-function relationships, overview
metabolism
the NADPH is oxidized to NADP+ by the PaODH in the presence of Pseudomonas aeruginosa nicotianamine synthase (PaNAS), S-adenosyl-L-methionine (SAM) and the correct amino acid and 2-oxo acid substrates. Pyruvate, oxaloacetate, and 2-oxoglutarate are screened with SAM, but no oxidation is observed, suggesting that SAM alone is not sufficient as a substrate for PaNAS. Screening of 42 L- and D-amino acid substrates in combination with pyruvate, oxaloacetate, or 2-oxoglutarate reveals that several amino acids, L-threonine, L-asparagine, and L-hydroxyproline (L-Hyp), show limited turnover, while the combination of L-histidine and 2-oxoglutarate results in significant oxidation of NADPH by PaODH. PaNAS is specific for L-histidine

structure-function analysis, stereochemic reaction, overview. Active site structure involving Asp153 and substrate binding analysis. The histidine is positioned to act as a general acid/general base deprotonating the nucleophile and then donating the proton back to the 2-carbon hydroxyl leading to water release and Schiff base formation. HisNA is oriented with the imidazole moiety deep in the active site to confer stereoselectivity. This places the primary amine of the aminobutyrate proximal to the plane between the hydride and His242, positioning the substrate for nucleophilic attack. The nicotinamide ring hydride is 8.5 A distant from the histidine proton, too far for catalysis, further supporting the necessity of domain closure
