摘要:Site-specific modifications of proteins are desirable in biotechnological applications such as biopharmaceuticals, immunotherapy, vaccines, and are useful in chemical biology. Gluconoylation is a non-enzymatic, covalent, post-translational modification commonly observed on N-terminal His-Tags bearing proteins. We synthesized glucono-1,5-lactone derivatives, including azido variants for selective acylation. High yield acylation is achieved by simply mixing derivatives with target protein amidst diverse conditions of temperatures, aqueous buffers, excipients, or complex cell lysate.

发明人：SELIFONOV SERGEY A; NEWMAN LISA M
权利人:MAXYGEN INC; SELIFONOV SERGEY A; NEWMAN LISA M
摘要:This invention provides improved polypeptides, including dioxygenases, dehydrogenases, ligases and transferases that are useful for the biocatalytic synthesis of compounds such as α-hydroxycarboxylic acids, and aryl- and alkyl-hydroxy and carboxylic acid compounds. The polypeptides provided herein are improved in properties such as regioselectivity, enzymatic activity, stereospecificity, and the like. Methods for obtaining recombinant polynucleotides that encode these improved polypeptides are also provided, as are organisms that express the polypeptides and are thus useful for carrying out said biocatalytic syntheses. Also provided by the invention are methods for increasing said solvent resistance of organisms that are used in the synthetic methods.
