Crystallization and preliminary X-ray diffraction analysis of the amidase domain of allophanate hydrolase from Pseudomonas sp. strain ADP
نویسندگان
چکیده
The allophanate hydrolase from Pseudomonas sp. strain ADP was expressed and purified, and a tryptic digest fragment was subsequently identified, expressed and purified. This 50 kDa construct retained amidase activity and was crystallized. The crystals diffracted to 2.5 Å resolution and adopted space group P21, with unit-cell parameters a = 82.4, b = 179.2, c = 112.6 Å, β = 106.6°.

Purification and characterization of allophanate hydrolase (AtzF) from Pseudomonas sp. strain ADP.
AtzF, allophanate hydrolase, is a recently discovered member of the amidase signature family that catalyzes the terminal reaction during metabolism of s-triazine ring compounds by bacteria. In the present study, the atzF gene from Pseudomonas sp. strain ADP was cloned and expressed as a His-tagged protein, and the protein was purified and characterized. AtzF had a deduced subunit molecular mass...
متن کاملCrystallization and preliminary x-ray crystallographic data of dienelactone hydrolase from Pseudomonas sp. B13.
Dienelactone hydrolase (EC 3.1.1.45) from Pseudomonas sp. B13 has been crystallized in a form suitable for high resolution x-ray diffraction study. The crystals are orthorhombic, the space group being P212121, with unit cell dimensions a = 48.9 A, b = 71.2 A, and c = 77.5 A. There appears to be 1 molecule in the asymmetric unit.
متن کاملComplete nucleotide sequence and organization of the atrazine catabolic plasmid pADP-1 from Pseudomonas sp. strain ADP.
The complete 108,845-nucleotide sequence of catabolic plasmid pADP-1 from Pseudomonas sp. strain ADP was determined. Plasmid pADP-1 was previously shown to encode AtzA, AtzB, and AtzC, which catalyze the sequential hydrolytic removal of s-triazine ring substituents from the herbicide atrazine to yield cyanuric acid. Computational analyses indicated that pADP-1 encodes 104 putative open reading ...
متن کاملEvidence that cysteine-166 is the active-site nucleophile of Pseudomonas aeruginosa amidase: crystallization and preliminary X-ray diffraction analysis of the enzyme.
Wild-type and site-specific mutants C166S and C166A (Cys-166-->Ser and Cys-166-->Ala respectively) of the amidase (acylamide amidohydrolase, EC 3.5.1.4) from Pseudomonas aeruginosa were expressed in Escherichia coli by using the vector pKK223-3. Both mutant proteins were catalytically inactive but showed complete cross-reactivity with polyclonal antiserum raised against the wild-type enzyme, as...
متن کاملStructural analysis of bacteriophage-encoded peptidoglycan hydrolase domain KMV36C: crystallization and preliminary X-ray diffraction.
The C-terminus of gp36 of bacteriophage varphiKMV (KMV36C) functions as a particle-associated muramidase, presumably as part of the injection needle of the phiKMV genome during infection. Crystals of KMV36C were obtained by hanging-drop vapour diffusion and diffracted to a resolution of 1.6 A. The crystals belong to the cubic space group P432, with unit-cell parameters a = b = c = 102.52 A. KMV...
