With Pseudomonas aeruginosa PAO1 dihydropyrimidinase; In aq. buffer; at 25℃;pH 8.0;Enzymatic reaction;Kinetics; | A rapid spectrophotometric assay was used to determine the enzymatic activity according to a previously described protocol for hydantoinase [12], allantoinase [11,15], dihydroorotase [11,15], and imidase [3,4,5]. Dihydrouracil, 5-propyl-hydantoin, and phthalimide were used as substrates. Unless explicitly stated otherwise, <strong>[504-07-4]dihydrouracil</strong> (2 mM) was used as the substrate in the standard assay of dihydropyrimidinase. Briefly, the decrease in absorbancy at 230, 248, and 298 nm was measured upon hydrolysis of <strong>[504-07-4]dihydrouracil</strong>, 5-propyl-hydantoin, and phthalimide as the substrate at 25C, respectively. To start the reaction, the purified dihydropyrimidinase (10-70 mug) was added to a 2 mL solution containing the substrate and 100 mM Tris-HCl (pH 8.0). Substrate hydrolysis was monitored with a UV/vis spectrophotometer (Hitachi U3300, Hitachi High-Technologies, Tokyo, Japan). The extinction coefficient of each substrate was determined experimentally by direct measurement with a spectrophotometer. The extinction coefficients of <strong>[504-07-4]dihydrouracil</strong>, 5-propyl-hydantoin, and phthalimide were 0.683 mM-1cm-1 at 230 nm, 0.0538 mM-1cm-1 at 248 nm, and 3.12 mM-1cm-1 at 298 nm, respectively. The initial rates of change were a function of enzyme concentration within the absorbance range of 0.01-0.18 min-1. A unit of activity was defined as the amount of enzyme catalyzing the hydrolysis of 1 mumol substrate/min, and the specific activity was expressed in terms of units of activity per milligram of enzyme. The kinetic parameters Km and Vmax were determined from a non-linear plot by fitting the hydrolyzing rate from individual experiments to the Michaelis-Menten equation (Enzyme Kinetics module of Sigma-Plot; Systat Software, Chicago, IL, USA). |

Standard enzymatic reaction was carried out with (R,S)-5-METDHU as substrate (10 mM) in 100 mM sodium phosphate buffer (pH 8.0), at 30 ?C in 1 ml reaction volume. Aliquots of 100 l were taken and stopped by addition of 900 l of 1% H3PO4. After centrifuging, the resulting supernatants were analyzed by high-performance liquid chromatography (HPLC). The HPLC system (LC2000Plus HPLC System, Jasco, Madrid, Spain) equipped with a Luna C18 column (4.6×250 mm; Phenomenex, Madrid, Spain) was used to determine the concentrations of 5-METDHU, N-carbamoyl-3-AiBA, and 3-AiBA. The mobile phase used in the analysis was 95% phosphoric acid (20 mM, pH 3.2) and 5% methanol, pumped at a flow rate of 1 ml min-1. The UV detector was fixed at 200 nm. All reactions conducted for the bienzymatic system characterization were carried out in triplicate. Optimal temperature of the bienzymatic system was evaluated from 25 to 60 ?C. Thermal stability was measured after 24 h of preincubation at temperatures from 4 to 50 ?C. A pH range of 6.0-9.0 was assayed (sodium phosphate and Tris/HCl buffers), at a concentration of 100 mM. Standard enzymatic reaction was then carried out with the Ni-amended At car (1 M) and SmelDhp (1 M) enzymes. The reaction progress was monitored by HPLC analysis as described above. |
