- An object of the present invention is to provide a means capable of performing accurate measurement even in a high concentration region where accurate measurement was impossible in the conventional method. Disclosure of the invention
- FIG. 2 is a graph showing the difference in creatine consumption in the presence (curve 4) and in the absence (curve 3) of the 6-phosphodalconolactonase of the present invention.
- the measuring method and the measuring composition of the present invention comprise newly coexisting 6-phosphodalconolactonase in a conventional G6P measuring system.
- 6-phosphogluconolactonase is present in the dehydrogenation reaction of the above formula (I).
- the present invention can be used in any method in which the entire reaction system comprising the formulas (VI) and (I) is carried out in one step or in multiple steps. Therefore, 6-phosphodalconolactonase may be present from the beginning of the whole reaction system or added later.
- the test sample for the G1c measurement method is not particularly limited as long as it is a sample that may contain Glc, but it is particularly blood or a liquid derived from blood (particularly serum or plasma), or urine. Alternatively, a tissue extract can be mentioned.
- reaction of the formula (2) progresses relatively rapidly with PH 8.5 or more when 6-phosphodalconolactonase according to the present invention is not present. It was found that the reaction of equation (2) progressed relatively quickly at pH 8.5 or higher, whereas the reaction progress rate of equation (2) was extremely slow at pH 8.5 or lower.
- CK (derived from egret muscle: Boehringer's Mannheim) is added to human pool serum at a concentration of 5000 UZ liter, then diluted with purified water, and 10 species (500 UZ, 1000 U, 1500 UZ, 2000 U / L) , 2500 UZ liters, 3000 UZ liters, 3500 UZ liters, 4000 UZ liters, 4500 UZ liters, and 5000 U liters).
- Glucose was diluted with purified water to prepare diluted solutions having concentrations of 40 OmgZd1, 700 mgZdl and 1000 mg / dl.
- curve 5C shows 6-phosphodalconorak in a diluted solution of 40 mg of glucose / d1.
- Curve 5E shows 6-Phosphodalconolactonase in a 400 mg / d 1 glucose solution
- Curve 6C shows 6-Phosphogluconolactonase in a 70 OmgZd 1 glucose solution.
- Curve 6E shows the addition of 6-phosphodalconolactonase in a 70 Omg / d1 glucose dilute solution
- Curve 7C shows the absence of 6-Phosphodalconolactonase in a 1000 mg / d1 glucose dilute solution.
- Curve 7E shows the results of adding 6-phosphodalconolactonase to a diluted solution of glucose 100 Omg / d1 and curve 8 shows 6-phosphodalconolactone in purified water without glucose. The result when the enzyme was added is shown.
- Pseudomonas fluorescens Pseudomonas fluorescens: RI MD 1615005; obtained from Osaka University Research Institute for Microbial Diseases
- Penassay broth manufactured by Diico
- This culture was further cultured in a Heart Fusion medium at 30 ° C. for one day.
- the obtained culture was centrifuged to collect bacteria. After washing with saline, the cells were disrupted by ultrasonication in Tris buffer and further centrifuged. The supernatant was fractionated with ammonium sulfate at pH 7.5,
- Solution D The solution was prepared with 10 OmM imidazo-mono-acetic acid buffer (PH 6.5) containing 1 OmM magnesium chloride so that NADP was 0.85 mM and G6P was 0.08 mM.
- Solution F 6—PGDH ammonium sulfate suspension (12 OU / m 1: Kirk-Mannheim).
- ⁇ is the change in absorbance
- T is the reaction time (mi ⁇ )
- ⁇ is the extinction coefficient of NAD ⁇ (6.22 cmV / mo 1)
- d is the cell length (cm)
- V is The final liquid (m 1)
- V is the liquid (m 1) of the 6-phosphodalconolactonase-containing liquid
- DF is the dilution ratio of the 6-phosphodalconolactonase-containing liquid.
- the present invention provides a method for producing 6-phosphogalconic acid (6PG) from glucose-6-phosphate (G6P) by allowing 6-phosphogluconolactonase to be present in a dehydrogenation reaction step. It accelerates the reaction to PG and enables quick, accurate, and highly accurate measurements.
- physiologically active substances contained in various biological samples such as creatine kinase (CK), which is a diagnostic index for myocardial infarction and muscular dystrophy, and amylase (AMY ) Or by quantitatively inducing G6P from glucose (G1c), which serves as a diagnostic indicator for diabetes and the like, and further producing NAD (P) H, and measuring the amount thereof, thereby achieving the aforementioned physiological activity.
