Publication number: 20190359965Abstract: Provided herein are novel materials and methods for site-specific incorporation of phosphotyrosines into proteins. The novel methods of the invention encompass the use of a novel aminoacyl tRNA synthetase capable of charging compatible tRNAs with a phosphotyrosine precursor.

Methylopila sp. that produces enzymes is subjected to cell immobilization, and is then applied to the biological resolution of a racemate (R,S)-?-ethyl-2-oxo-1-pyrrolidineacetic acid ethyl ester to prepare high optically pure (S)-?-ethyl-2-oxo-1-pyrrolidineacetic acid ethyl ester, which is further subjected to a hydrolysis reaction to obtain (S)-?-ethyl-2-oxo-1-pyrrolidineacetate. The present invention achieves a high conversion yield up to 50.0% or more, a good stereoselectivity, and an enantiomeric excess value e.e.s(%) of (S)-?-ethyl-2-oxo-1-pyrrolidineacetic acid ethyl ester not less than 99.5; the catalytic efficiency is high; the concentration of the racemic substrate in the resolution reaction is up to 500 g/L, the reaction time does not exceed 15 h, the number of reuse times of the immobilized cells is not lower than 35.Type: ApplicationFiled: September 19, 2017Publication date: November 28, 2019Inventors: Yanming Xiao, Likun Zhang, Minfan Qian, Yanbing Yan, Weiping Tan

Publication number: 20190360013Abstract: An enzymatic method of making a polynucleotide is provided. The method includes combining a selected nucleotide triphosphate, one or more cations, a template-independent polymerase, and an associated processivity factor in an aqueous reaction medium including a target substrate comprising an initiator sequence and having a 3? terminal nucleotide attached to a single stranded portion, such that the template-independent polymerase and the associated processivity factor interact with the target substrate under conditions which covalently add one or more of the selected nucleotide triphosphate to the 3? terminal nucleotide. Also provided are mutant template-independent polymerases having a processivity factor attached thereto.Type: ApplicationFiled: December 4, 2017Publication date: November 28, 2019Applicant: President and Fellows of Harvard CollegeInventors: Kettner John Frederick GRISWOLD, JR., Brian M. TURCZYK, Daniel Jordan WIEGAND, George M. CHURCH, Alexander GARRUSS

Publication number: 20190360014Abstract: The current invention reports a promoter that has the nucleic acid sequence of SEQ ID NO: 02 or SEQ ID NO: 03 which is a human CMV major immediate-early (hCMV-MIE) promoter/enhancer with C to G point mutation at position ?41 and/or ?179 relative to the transcription start site. This new promoter is especially useful for the production of polypeptides at large scale as it shows reduced promoter silencing and improved polypeptide production.Type: ApplicationFiled: May 3, 2019Publication date: November 28, 2019Applicant: Hoffmann-La Roche Inc.Inventors: Ulrich Goepfert, Benjamin Moritz
