Purification, crystallization and preliminary crystallographic analysis of DehIVa, a dehalogenase from Burkholderia cepacia MBA4.
DehIVa is one of two dehalogenases produced by the soil- and water-borne bacterium Burkholderia cepacia MBA4. It acts to break down short-chain halogenated aliphatic acids through a nucleophilic attack and subsequent hydrolysis of an enzyme-substrate intermediate to remove the halide ions from L-enantiomers substituted at the C2 position (e.g L-2-monochloropropionic acid). Dehalogenases are an ...
متن کاملCrystallographic analysis of 1,2,3-trichloropropane biodegradation by the haloalkane dehalogenase DhaA31.
Haloalkane dehalogenases catalyze the hydrolytic cleavage of carbon-halogen bonds, which is a key step in the aerobic mineralization of many environmental pollutants. One important pollutant is the toxic and anthropogenic compound 1,2,3-trichloropropane (TCP). Rational design was combined with saturation mutagenesis to obtain the haloalkane dehalogenase variant DhaA31, which displays an increas...
متن کاملStereoselectivity and conformational stability of haloalkane dehalogenase DbjA from Bradyrhizobium japonicum USDA110: the effect of pH and temperature.
The effect of pH and temperature on structure, stability, activity and enantioselectivity of haloalkane dehalogenase DbjA from Bradyrhizobium japonicum USDA110 was investigated in this study. Conformational changes have been assessed by circular dichroism spectroscopy, functional changes by kinetic analysis, while quaternary structure was studied by gel filtration chromatography. Our study show...
متن کاملCrystallization and preliminary crystallographic analysis of human serine dehydratase.
L-Serine dehydratase (SDH) catalyzes the pyridoxal phosphate (PLP) dependent deamination of L-serine to yield pyruvate. Recombinant human serine dehydratase was crystallized by the hanging-drop vapour-diffusion method. Crystals were grown at 291 K using (NH4)(2)SO4 as precipitant. Diffraction data were obtained to a resolution of 2.5 A from a single frozen crystal using Cu Kalpha radiation. The...
متن کاملCrystallization and preliminary crystallographic analysis of allograft inflammatory factor 1.
Allograft inflammatory factor-1 (AIF-1) is a 17-kDa IFN-gamma inducible Ca2+-binding EF-hand protein involved in immune dysfunction and smooth muscle cell activation. AIF-1 was solubly expressed in E. coli and purified. Crystals of AIF-1 were grown at 291 K using PEG-8000 as precipitant. Diffraction by the AIF-1 crystal extends to 3.3 A resolution, and the crystal belongs to the space group P4(...
