  • Patent number: 11421255
    Abstract: A method for enzymatic preparation of fludarabine phosphate, comprising reaction of fludarabine with a high-energy phosphate compound under the action of deoxyribonucleic acid kinase. According to said method, acetate kinase and acetyl phosphate free acid or acetyl phosphate are also added. The technical problems present in the existing processes are successfully addressed by employing the enzymatic process to prepare the fludarabine phosphate. The usage of the high-energy phosphate compound is reduced by means of adding acetate kinase to recycle and regenerate a small amount of the high-energy phosphate compound, thereby reducing the generation of by-products having similar structures to the fludarabine phosphate, enhancing the operation convenience of purification steps in the industrial production of the fludarabine phosphate. The process is environment friendly, the reaction conditions are moderate, the cost is low, and the yield and the purity of the product obtained are high.

  • Publication number: 20110250651
    Abstract: Disclosed is a method of producing 5?-guanosine monophosphate using a novel microorganism which has a malate dehydrogenase activity higher than that of a wild-type, thereby showing improved ATP productivity. Also, a novel microorganism is disclosed. The method comprises: culturing the corynebacteria strain which is enhanced in malate dehydrogenase activity over the endogenous activity, thus producing ATP in high yield; producing XMP in the culture; adding to the culture an enzyme or microorganism having XMP amination activity; and obtaining GMP from the culture.

  • Publication number: 20110195461
    Abstract: The invention provides a non-naturally occurring microbial organism having an acetyl-CoA pathway and the capability of utilizing syngas or syngas and methanol. In one embodiment, the invention provides a non-naturally occurring microorganism, comprising one or more exogenous proteins conferring to the microorganism a pathway to convert CO, CO2 and/or H2 to acetyl-coenzyme A (acetyl-CoA), methyl tetrahydrofolate (methyl-THF) or other desired products, wherein the microorganism lacks the ability to convert CO or CO2 and H2 to acetyl-CoA or methyl-THF in the absence of the one or more exogenous proteins. For example, the microbial organism can contain at least one exogenous nucleic acid encoding an enzyme or protein in an acetyl-CoA pathway. The microbial organism is capable of utilizing synthesis gases comprising CO, CO2 and/or H2, alone or in combination with methanol, to produce acetyl-CoA.
