Strukturní studie halogenalkandehalogenasy DgaA z \kur{Glaciecola agarilytica} NO2
BERKOVÁ, Ivana
Haloalkane dehalogenases (HLDs) are microbial enzymes that have attracted significant interest because of their ability to catalyze the irreversible hydrolysis of a wide range of halogenated compounds. These enzymes can be used as potential applicants in industrial catalysis, in the bioremediation and the biosensing of environmental pollutants. Novel haloalkane dehalogenase DgaA (EC 3.8.1.5, HLDs) belonging to the superfamily of / hydrolases, was isolated from a psychrophilic and moderately halophilic organism, Glaciecola agarilytica NO2, that was found in marine sediment collected from the East Sea, Korea. Main target of this thesis was the processing of diffraction data from crystals of DgaA proteins and subsequent solving and refinement of structure of studied protein.
Experimental methods for phase determination /MIR,MAD,SAD/ in crystallography of biological macromolecules
Brynda, Jiří
Importance of unbiased phases in post genomic era is emphasized. Article describes the classical methods of phase determination: 1) Multiple Isomorphous replacement, heavy-atom derivative (MIR) 2) Multiple Anomalous Dispersion (MAD) Phasing 3) Single Anomalous Dispersion (SAD) Phasing The better your initial, experimental map is, the more model you will be able to build confidently into this unbiased map before proceeding to phase combination. MAD phases result from perfectly isomorphous data, and do not deteriorate at low resolution as do MIR phases. MIR phases, on the other hand, provide superior phasing power at low resolution resulting in better connectivity. Not surprising, the best maps are either MAD or combined MIR-MAD maps.
