Haloalkane dehalogenases: biotechnological applications.
Haloalkane dehalogenases (EC 3.8.1.5, HLDs) are α/β-hydrolases which act to cleave carbon-halogen bonds. Due to their unique catalytic mechanism, broad substrate specificity and high robustness, the members of this enzyme family have been employed in several practical applications: (i) biocatalytic preparation of optically pure building-blocks for organic synthesis; (ii) recycling of by-product...
متن کاملEvolving haloalkane dehalogenases.
Mechanistic insight into the biochemistry of carbon-halogen bond cleavage is rapidly growing because of recent structural, biochemical and computational studies that have provided further insight into how haloalkane dehalogenases achieve their impressive catalytic activity. An occluded water-free active-site cavity together with strong hydrogen bond donating groups reduce the transition state e...
متن کاملOrganohalide Respiring Bacteria and Reductive Dehalogenases: Key Tools in Organohalide Bioremediation
Organohalides are recalcitrant pollutants that have been responsible for substantial contamination of soils and groundwater. Organohalide-respiring bacteria (ORB) provide a potential solution to remediate contaminated sites, through their ability to use organohalides as terminal electron acceptors to yield energy for growth (i.e., organohalide respiration). Ideally, this process results in non-...
متن کاملViability of Coliform Bacteria in Antarctic Soil.
Boyd, William L. (Ohio State University, Columbus) and Josephine W. Boyd. Viability of coliform bacteria in antarctic soil. J. Bacteriol. 85:1121-1123. 1963.-The distribution of coliform bacteria in soils of Ross Island and the nearby mainland was studied. None was found in almost all of the samples collected, including some from the Adelie penguin rookeries at Cape Royds and Cape Crozier and i...
متن کاملBacteria-phage antagonistic coevolution in soil.
Bacteria and their viruses (phages) undergo rapid coevolution in test tubes, but the relevance to natural environments is unclear. By using a "mark-recapture" approach, we showed rapid coevolution of bacteria and phages in a soil community. Unlike coevolution in vitro, which is characterized by increases in infectivity and resistance through time (arms race dynamics), coevolution in soil result...
