专利号:US-2024391961-A1 优先权日:2021-08-25 标题:Autonomous organisms for synthesis of permanently phosphorylated proteins 发明人:COOLEY RICHARD B; MEHL RYAN A; ZHU PHILLIP 权利人:UNIV OREGON STATE 摘要:Embodiments of the present disclosure provide compositions and methods for biosynthesizing a stable, functional mimic of phosphoserine. The compositions and methods described herein genetically program a host cell to express a biosynthetic pathway that can synthesize the amino acid, 2-amino-4-phosphobobutyric acid, that is a non-hydrolyzable phosphoserine (nhpSer) because it contains a carbon-phosphorus, e.g., phosphonate, bond. In one embodiment the genetically programed cells express the enzymes of a pathway from a Streptomyces bacterium . In some embodiments, nhpSer is translationally incorporated into protein of interest at one or more programmed UAG amber codons using Genetic Code Expansion (GCE) technology.
专利号:US-11781122-B2 优先权日:2017-07-11 标 题:Ectoine-producing yeast 发明人:LOUIS DOMINIQUE; JAILLARDON KARINE; THOMAS DOMINIQUE 权利人:ALDERYS; GIVAUDAN SA 摘要:The present invention relates to the field of bio-production of ectoine. There is a need in the art for ectoine production methods allowing its highly efficient synthesis and secretion. The solution proposed in the present invention is the use of a genetically modified yeast comprising many modifications as described in the present text.
