Crystallization 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 کاملTransformation of Low Concentrations of 3-Chlorobenzoate by Pseudomonas sp. Strain B13: Kinetics and Residual Concentrations.
The transformation of 3-chlorobenzoate (3CB) and acetate at initial concentrations in the wide range of 10 nM to 16 mM was studied in batch experiments with Pseudomonas sp. strain B13. Transformation rates of 3CB at millimolar concentrations could be described by Michaelis-Menten kinetics (K(infm), 0.13 mM; V(infmax), 24 nmol (middot) mg of protein(sup-1) (middot) min(sup-1)). Experiments with ...
متن کاملUnusual integrase gene expression on the clc genomic island in Pseudomonas sp. strain B13.
An unusual type of gene expression from an integrase promoter was found in cultures of the bacterium Pseudomonas sp. strain B13. The promoter controls expression of the intB13 integrase gene, which is present near the right end of a 105-kb conjugative genomic island (the clc element) encoding catabolism of aromatic compounds. The enzymatic activity of integrase IntB13 is essential for site-spec...
متن کاملPurification 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 کاملGene transfer from a bacterium injected into an aquifer to an indigenous bacterium.
Two novel 3-chlorobenzoate-degrading bacteria were previously isolated from an aquifer in which no such bacteria could be enriched prior to the introduction of the 3-chlorobenzoate-degrading strain, Pseudomonas sp. B13. To understand the origin of 3-chlorobenzoate-degrading genes in the two novel isolates, the 16S ribosomal RNA, clcD (dienelactone hydrolase) and clcA (chlorocatechol oxygenase) ...
