标题:Materials and methods for the photodirected synthesis of oligonucleotide arrays

摘要:Materials and methods for photodirected synthesis of oligonucleotide arrays on a solid substrate by photodirected synthesis are disclosed which employ a film formed from (i) a photoacid generator that on photolysis generates acid that is capable of directly removing the protecting group of the linker molecules or oligonucleotides and (ii) a polymer substantially lacking electronegative heteroatoms that are capable of hydrogen bonding with photogenerated acid. Methods of synthesizing an oligomer arrays are also described that use a film that restricts diffusion of reactants and products on the substrate during synthesis of the array and which includes a precursor of a deprotecting reagent. The method involves removing one or more of the non-required products of the deprotection reaction from the reactive array elements at which they are produced during the reaction, in order to displace the deprotection reaction towards completion.

摘要:The present invention provides engineered polypeptides that are useful for the asymmetric synthesis of β-hydroxy-α-amino acids under industrial-relevant conditions. The engineered polypeptides disclosed in this invention were developed through directed evolution based on the ability of catalytic synthesis of (2S, 3R)-2-amino-3-hydroxy-3-(4-nitrophenyl) propanoic acid. The present disclosure also provides polynucleotides encoding engineered polypeptides, host cells capable of expressing engineered polypeptides, and methods of producing β-hydroxy-α-amino acids using engineered polypeptides. Compared to other processes of preparation, the use of the engineered polypeptides of the present invention for the preparation of β-hydroxy-α-amino acids results in high purity of the desired stereoisomers, mild reaction conditions, low pollution and low energy consumption. So, it has good industrial application prospects.

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.

摘要:Disclosed is a method for the combined synthesis of at least two vinylic monomers, at least one of which being an acrylic compound, comprising subjecting a monoconjugated alkene-1-carboxylic compound to reaction with a C 2 -C 4 alkene under conditions of olefin cross-metathesis. The invention is particularly useful for extracting value from protein side streams. Upon protein hydrolysis, suitable amino acids (preferably phenylalanine or tyrosine) are subjected to reductive amination so as to form the corresponding alkene-1-carboxylic acid. Preferably after esterification and separation, this is used in cross-metathesis for the concomitant production of styrene resp. hydroxy styrene, and acrylates. The invention is applicable more widely, to the synthesis of olefins on the basis of carbohydrates, naturally occurring phenolic components, natural protein resources, or amino acids obtained from fermentations.
