标题:Loktanella Atrirudea 芳香氨裂解酶的生物催化潜力
摘要:来自loktanella Atrirudea (La Aal) 的芳香氨裂解酶对 3,4-二甲氧基反式肉桂酸表现出高活性,而对天然 Aal 底物的活性却出人意料地降低.在最佳反应条件下,La Aal 表现出多种肉桂酸转化的多功能性.虽然la Aal 可能被归类为酪氨酸氨裂解酶(tal,Ec 4.3.1.23),但其强烈独特的属性表明其在非天然苯丙氨酸的转化中发挥着重要作用.

标题 :Genetic engineering bacterium for de novo synthesis of cis,cis-muconic acid by taking glucose as substrate and applications thereof
发明人：TAN TIANWEI; LI MENGLEI
权利人:UNIV BEIJING CHEM TECH
摘要:The present invention discloses a genetic engineering bacterium for de novo synthesis of cis,cis-muconic acid by taking glucose as a substrate and applications thereof, and belongs to the technical field of genetic recombination and metabolic engineering. The genetic engineering bacterium for de novo synthesis of cis,cis-muconic acid (MA) by taking glucose as the substrate disclosed in the present invention is modified with chassis microbes, and includes recombinant Corynebacterium glutamicum for a cis,cis-muconic acid pathway construction module and an intermediate high-yield module. Production capacity of strains is greatly improved; MA of 90.2 g/L is finally obtained in fermentation liquor; and possibilities are provided for green and low-cost production of numerous chemicals such as adipic acid and nylon-66.

标 题:Synthesis of purine locked nucleic acid analogues
发明人：KOCH TROELS; JENSEN FLEMMING REISSIG
权利人:SANTARIS PHARMA AS
摘要:The present invention relates to a new method for the synthesis of purine LNA (Locked Nucleic Acid) analogues which provides a higher overall yield. The method comprising a regioselective 9-N purine glycosylation reaction followed by a one-pot nucleophilic aromatic substitution reaction of the 6-substituent in the purine ring and simultaneous nucleophile-induced intramolecular ring closure of the C-branched carbohydrate to form novel purine LNA analogues. The novel strategy is illustrated by the synthesis of the novel compound (1S,3R,4R,7S)-7-benzyloxy-1-methanesulfonylmethyl-3-(guanin-9-yl)-2,5-dioxabicyclo[2.2.1]heptane which is easily converted into (1S,3R,4R,7S)-7-hydroxy-1-hydroxymethyl-3-((2-N-isobutyrylguanin-9-yl)-2,5-dioxabicyclo[2.2.1]heptane after isobutyryl protection of the 2-amino purine group and subsequent substitution of 1-methanesulfonyl with benzoate, debenzoylation and debenzylation.

摘要:Some embodiments relate to genetically engineered bacterial strains for modulation of levels of the bacterial metabolite 4-ethylphenol (4EP) and its sulfated form, 4-ethylphenyl sulfate (4EPS). In some embodiments, the bacteria reduce or inhibit production of 4EP or 4EPS in the gut of a subject. The bacteria can ameliorate, delay the onset, or reduce the likelihood of one or more symptoms associated with anxiety and/or autism spectrum disorder (ASD) in the subject.
