Definitions
- the present invention relates to a method for producing N-acetylneuraminic acid.
- N-Acetyl neuraminic acid is the most ubiquitous sialic acid substance, is widely distributed in tissues, fluids, secretions, etc. of living organisms, and is involved in hemagglutination, intercellular recognition, turnover of serum proteins, etc. This is an important substance known.
- N-acetylneuraminic acid is conventionally produced by the hydrolysis of capsular polysaccharide of Escherichia coli, as well as the hydrolysis of natural products such as swallow's nest, chicken eggs and milk. It is also manufactured by
- Kim et al. J. Am. Chem. Soc.], 110, 648 1-64 8 6 (198 8) is a method for reacting N-acetyl mannosamine with pyruvate in the presence of N-acetyl neuraminic acid lyase to obtain N-acetyl neuraminase.
- a method for producing acid is reported.
- this method lacks practicality because it uses N-acetylmannosamine, which is expensive and difficult to obtain in large quantities, as a raw material.
- N-acetyl neuraminic acid Reaction of N-acetylglucosamine with pyruvate in the presence of N-acetylneuraminic acid lyase and epimerase A method for obtaining N-acetyl neuraminic acid has also been proposed [for example, Kiegl (Kieg 1) et al., Angew. Chem. Int. Ed. Engl., 30_, 82] 7-8282 (1991)).
- N-acetyl darcosamine is sequentially converted into N-acetylmannosamine by the action of epimerase, and then this N-acetylmannosamine is subjected to the action of N-acetylneuraminic acid lyase to give N-acetylethylnosamine. Converted to acetyl neuraminic acid.
- epimerase that isomerizes N-acetyldarcosamine
- the conversion rate of N-acetyltilcosamine to N-acetylneuraminic acid is 25%. Low, this method is not practical.
- An object of the present invention is to provide a simple and practical method for producing N-acetylneuraminic acid.
- the present inventors have conducted intensive studies in order to achieve the above object, and as a result, in order to avoid the inactivation of the enzyme in the past and to determine the optimal pH of N-acetylneuraminic acid lyase. 7.7) The alkalinity that was not used to deviate from N-acetylacetylglucosamine and pyruvate in the high pH region in the presence of N-acetylneuraminic acid lyase When reacted, the inactivation of the enzyme is suppressed by the protective effect of the substrates N-acetylglucosamine and pyruvate, and N-acetyl We found that dalcosamine was effectively converted to N-acetyl neuraminic acid.
- the present invention provides a method for producing N-acetylneuraminic acid, which comprises reacting N-acetylneuraminic acid lyase in the presence of N-acetyldarcosamine and pyruvate under alkaline conditions. It provides a manufacturing method.
- the term "hydrophilic conditions" means that the pH of the reaction solution is usually about 8 to 12, preferably about 9 to 12, more preferably about 10 to 12, and most preferably about 10 to 12. It is preferably about 10 to 11. If the pH of the reaction mixture is too low, little or no conversion of N-acetylglucosamine to N-acetylmannosamine occurs, so the reaction does not proceed and the pH of the reaction mixture becomes too high. And N-acetyl neuraminic acid lyase are inactivated, and the reaction yield is reduced.
- the reaction temperature is about 10 to 80 ° C, preferably about 20 to 50 ° C, and the reaction time is about 30 minutes to 240 hours, preferably 20 hours to 12 hours. It is about 0 hours. The reaction is carried out in a stationary or stirred state.
- the concentration of each component in the reaction solution is as follows. (1)
- the amount of N-acetyldarcosamine used is not particularly limited, and it can be used at any concentration up to the saturation solubility, but is preferably about 1 to 20 WZV%, more preferably 10 to 10%. Used around 20 WZV%.
- the amount of pyruvic acid used is not particularly limited and can be used at any concentration up to the saturation solubility, but is preferably about 1 to 20 WZV%, more preferably about 10 to 20 WZV%. Used once.
- the amount of N-acetyl neuraminic acid lyase used is not particularly limited and can be selected from a wide range according to the amount of the substrate, but is preferably 0.01 U or more per 1 ml of the reaction solution, more preferably. 0.1 U or more: about LOOU, most preferably about 1 U to 50 U.
- the concentrations of the substrates N-acetylglucosamine and pyruvate are too low, the absolute amount of N-acetylneuraminic acid produced will decrease, and the concentrations of the substrates N-acetyldarcosamine and pyruvate will decrease. If it is too high, the ratio of N-acetyl neuraminic acid at the end of the reaction will decrease, making purification difficult.
- sodium hydroxide, potassium hydroxide, lithium hydroxide or the like may be used as a method for adjusting the pH of the reaction solution to alkalinity.
- N-Acetylglucosamine can be used in any form of free base and salts such as hydrochloric acid and sulfuric acid.
- Pyruvic acid can be used in any form of a free acid and a salt such as sodium and potassium.
- N-Acetylneuraminic acid lyase can use enzymes derived from both animal and plant sources, and is not significantly affected by the purity of the enzyme.
- N-Acetylneuraminic acid produced by the method of the present invention can be easily separated and purified from the reaction solution by known means. For example, after purification by ion exchange column chromatography, concentration can be performed to obtain a crystal in an organic solvent.
- the reaction is carried out under alkaline conditions in which the enzyme is conventionally deactivated by the enzyme protecting action of the substrate. Therefore, the following excellent effects can be achieved.
- N-acetyldarcosamine which is inexpensive and available in large quantities, the reaction can be performed at a high substrate concentration, enabling mass synthesis of N-acetylneuraminic acid.
- N-acetylneuramin can be obtained in a high yield of 50% or more (mol ratio) to N-acetylacetylglucosamine. Acid can be produced.
- reaction product was isolated by ion exchange chromatography using D0weX1 (registered trademark, manufactured by Dow Chemical Co., Ltd.), concentrated, and then 10 g of needle-like N-acetylneuraminic acid was obtained according to a conventional method. Obtained.
- N-acetyldarcosamine and 200 g of pyruvate were dissolved in 100 mM phosphate buffer ( ⁇ ⁇ ⁇ .0), and N-acetylneuraminic acid lyase was obtained. U was added to make the total amount 1 liter, and the reaction was carried out at 35 ° C for 120 hours. The amount of N-acetylneuraminic acid in the reaction solution was 56 g, and the conversion to the N-acetylglucosamine used was about 40%.
- the reaction was performed under the same conditions as in Example 2 except that the concentrations of N-acetylglucosamine and pyruvate, the concentration of N-acetylneuraminate lyase, the reaction time, and the pH of the phosphate buffer were changed. Went.
