专利号:US-5824472-A 优先权日:1986-03-24 标 题 :Process for the synthesis of sugar nucleotides using recombinant-DNA methods 发明人:BETLACH MICHAEL R; DOHERTY DANIEL H; VANDERSLICE REBECCA W 权利人:MONSANTO CO 摘要:A recombinant-DNA mediated method for the synthesis of sugar nucleotides is disclosed. This method utilizes portable DNA sequences capable of directing the microbial synthesis of various enzymes that catalyze the synthesis of sugar nucleotides, including UDP-glucose, UDP-glucuronic acid and GDP-mannose. The sugar moieties of these sugar nucleotides may subsequently be incorporated into industrially-useful polysaccharides such as xanthan gum. It has been found that vectors containing the portable DNA sequences described herein are capable both of causing sugar nucleotide production in microorganisms previously incapable of such synthesis and of causing increased sugar nucleotide production in organisms capable of synthesizing small quantities of these compounds. In particular, plasmids pAS7, pAS9 and pTS13 are disclosed. These plasmids are capable of directing sugar nucleotide synthesis in various hosts, including Xanthomonas sp. such as X. campestris and other organisms such as E. coli and various Pseudomonas sp.
专利号:US-6350595-B1 优先权日:1997-10-28 标题:Synthesis of polynucleotides having random sequences 发明人:NEUNER PHILIPPE 权利人:ISTITUTO DI RICERCHE DI MOLECO 摘要:Subject of this invention is a process for the chemical synthesis of polynucleotides having totally or partially random sequences, based on the utilization, as synthesis monomer units for the random sequence part, or presynthesized mononucleotides and dinucleotides. Said synthesis is carried out on separate supports, so that on each of those supports is alternated at least one reaction cycle wherein a mixture of said dinucleotides is bound, with at least one reaction cycle wherein a mononucleotide is bound, and that in a preferred embodiment at the end of the n cycles required for a codon synthesis, the supports are mixed and then redivided into one or more reaction containers. The resulting polynucleotides are such that, for the random sequence part, each trinucleotide unit is fit to match only a limited number of codons, predefined for each unity in number and sequence, and the genetic code degeneracy effects can thus be eliminated. FIG. 1 shows the chemical structure of the dinucleotides utilized as monomer units for the synthesis of codons forming the final sequence.

专利号:US-10865390-B2 优先权日:2018-02-12 标 题 :Alcohol dehydrogenase mutant and application thereof in synthesis of diaryl chiral alcohols 发明人:NI YE; ZHOU JIEYU; XU GUOCHAO; WANG YUE 权利人:UNIV JIANGNAN 摘要:The present disclosure discloses an alcohol dehydrogenase mutant and application thereof in synthesis of diaryl chiral alcohols, and belongs to the technical field of bioengineering. The alcohol dehydrogenase mutant of the present disclosure has excellent catalytic activity and stereoselectivity, and may efficiently catalyze the preparation of a series of chiral diaryl alcohols in R- and S-configurations. By coupling alcohol dehydrogenase of the present disclosure to glucose dehydrogenase or formate dehydrogenase, the synthesis of chiral diaryl alcohol intermediates of various antihistamines may be achieved. Compared with the prior art, a method for preparing diaryl chiral alcohols through asymmetric catalytic reduction using the alcohol dehydrogenase of the present disclosure has the advantages of simple and convenient operation, high substrate concentration, complete reaction and high product purity, and has great industrial application prospects.
