Structure and Inhibition of Tuberculosinol Synthase and Decaprenyl Diphosphate Synthase from Mycobacterium tuberculosis
We have obtained the structure of the bacterial diterpene synthase, tuberculosinol/iso-tuberculosinol synthase (Rv3378c) from Mycobacterium tuberculosis , a target for anti-infective therapies that block virulence factor formation. This phosphatase adopts the same fold as found in the Z- or cis-prenyltransferases. We also obtained structures containing the tuberculosinyl diphosphate substrate t...
متن کاملDecaprenyl diphosphate synthesis in Mycobacterium tuberculosis.
Z-prenyl diphosphate synthases catalyze the sequential condensation of isopentenyl diphosphate with allylic diphosphates to synthesize polyprenyl diphosphates. In mycobacteria, these are precursors of decaprenyl phosphate, a molecule which plays a central role in the biosynthesis of essential mycobacterial cell wall components, such as the mycolyl-arabinogalactan-peptidoglycan complex and lipoa...
متن کاملRv0989c encodes a novel (E)-geranyl diphosphate synthase facilitating decaprenyl diphosphate biosynthesis in Mycobacterium tuberculosis.
Mycobacterium tuberculosis (Mtb) has a highly complex cell wall, which is required for both bacterial survival and infection. Cell wall biosynthesis is dependent on decaprenyl diphosphate as a glyco-carrier, which is hence an essential metabolite in this pathogen. Previous biochemical studies indicated (E)-geranyl diphosphate (GPP) is required for the synthesis of decaprenyl diphosphate. Here w...
متن کاملStructure of Mycobacterium tuberculosis nucleoside diphosphate kinase R80N mutant in complex with citrate.
The crystal structure of the wild-type nucleoside diphosphate kinase from Mycobacterium tuberculosis at 2.6 Å resolution revealed that the intersubunit salt bridge Arg80-Asp93 contributes to the thermal stability of the hexamer (Tm = 76°C). On mutating Asp93 to Asn to break the salt bridge, the thermal stability dramatically decreased by 27.6°C. Here, on mutating Arg80 to Asn, the thermal stabi...
متن کاملIdentification of Mycobacterium Tuberculosis Complex, Using Molecular Methods
Abstract Background and Objective: A high level of homogeneity observed within all bacteria in the Mycobacterium tuberculosis complex makes a property that seriously challenges traditional biochemical-based identification methods of these pathogens in the laboratory. The work presented here was conducted to characterize Mycobacterium tuberculosis complex isolates in Golestan, Northern Iran. ...
