Physiology of the thermophilic acetogen Moorella thermoacetica.
Moorella thermoacetica (originally isolated as Clostridium thermoaceticum) has served as the primary acetogenic bacterium for the resolution of the acetyl coenzyme A (acetyl-CoA) or Wood-Lijungdahl pathway, a metabolic pathway that (i) autotrophically assimilates CO2 and (ii) is centrally important to the turnover of carbon in many habitats. The purpose of this article is to highlight the diver...
متن کاملEngineering of a functional thermostable kanamycin resistance marker for use in Moorella thermoacetica ATCC39073.
A transformation system for Moorella thermoacetica ATCC39073 was developed using thermostable kanamycin resistant gene (kanR) derived from the plasmid pJH1 that Streptococcus faecalis harbored. When kanR with its native promoter was introduced into uracil auxotrophic mutant of M. thermoacetica ATCC39073 together with a gene to complement the uracil auxotrophy as a selection marker, it did not g...
متن کاملA reversible electron-bifurcating ferredoxin- and NAD-dependent [FeFe]-hydrogenase (HydABC) in Moorella thermoacetica.
Moorella thermoacetica was long the only model organism used to study the biochemistry of acetogenesis from CO(2). Depending on the growth substrate, this Gram-positive bacterium can either form H(2) or consume it. Despite the importance of H(2) in its metabolism, a hydrogenase from the organism has not yet been characterized. We report here the purification and properties of an electron-bifurc...
متن کاملOxalate metabolism by the acetogenic bacterium Moorella thermoacetica.
Whole-cell and cell-extract experiments were performed to study the mechanism of oxalate metabolism in the acetogenic bacterium Moorella thermoacetica. In short-term, whole-cell assays, oxalate consumption was low unless cell suspensions were supplemented with CO(2), KNO(3), or Na(2)S(2)O(3). Cell extracts catalyzed the oxalate-dependent reduction of benzyl viologen. Oxalate consumption occurre...
متن کاملCharacterization of a three-component vanillate O-demethylase from Moorella thermoacetica.
The Moorella thermoacetica aromatic O-demethylase was characterized as an inducible three-component system with similarity to the methanogenic methanol, methylamine, and methanethiol methyltransferases and to the O-demethylase system from Acetobacterium dehalogenans. MtvB catalyzes methyl transfer from a phenylmethylether to the cobalt center of MtvC, a corrinoid protein. MtvA catalyzes transme...
