专利号:US-9938509-B2 优先权日:2010-12-08 标 题 :Biocatalysts and methods for the synthesis of armodafinil 发明人:ANG EE LUI; ALVIZO OSCAR; BEHROUZIAN BEHNAZ; CLAY MICHAEL D; COLLIER STEVEN J; EBERHARD ELLEN D; FAN FU; SONG SHIWEI; SMITH DEREK J; WIDEGREN MAGNUS; WILSON ROBERT; XU JUNYE; ZHU JUN 权利人:CODEXIS INC 摘要:The present invention relates to non-naturally occurring polypeptides useful for preparing armodafinil, polynucleotides encoding the polypeptides, and methods of using the polypeptides. The non-naturally occurring polypeptides of the present invention are effective in carrying out biocatalytic conversion of the (i) 2-(benzhydrylsulfinyl)acetamide to (−)-2-[(R)-(diphenylmethyl)sulfinyl]acetamide (armodafinil), or (ii) benzhydryl-thioacetic acid to (R)-2-(benzhydrylsulfinyl)acetic acid, which is a pivotal intermediate in the synthesis of armodafinil, in enantiomeric excess.
专利号:US-12378290-B2 优先权日:2019-09-05 标题:Method for protein nanowire synthesis and tunable control of nanowire length 发明人:REGUERA GEMMA; COSERT KRISTA MARIE 权利人:UNIV MICHIGAN STATE 摘要:Methods for synthesizing nanowires are provided. Modified PilA peptides are used as peptide building blocks for synthesizing the nanowires. The method places the peptide building blocks in an assembly buffer with a hydrophobe. Addition of a hydrophobe and molecular crowding by evaporation of the assembly buffer triggers the self-assembly of the peptide building blocks into fibers. Multiple elongation cycles of addition of peptide building blocks, mixing and evaporation are conducted to promote elongation of the fibers and synthesis of nanowires. Electronic characterization of the synthesized nanowires is provided.
