Unnatural Protein Engineering: Producing Proteins with Unnatural Amino Acids
Less than a decade ago, the ability to generate proteins with unnatural modifications was a Herculean task available only to specialty labs. Recent advances make it possible to generate reasonable quantities of protein with unnatural amino acids both in vitro and in vivo . The combination of solid-phase peptide synthesis and enzymatic or chemoselective ligation now permits construction of entir...
متن کاملAntibody conjugates with unnatural amino acids.
Antibody conjugates are important in many areas of medicine and biological research, and antibody-drug conjugates (ADCs) are becoming an important next generation class of therapeutics for cancer treatment. Early conjugation technologies relied upon random conjugation to multiple amino acid side chains, resulting in heterogeneous mixtures of labeled antibody. Recent studies, however, strongly s...
متن کاملProbing protein stability with unnatural amino acids.
Unnatural amino acid mutagenesis, in combination with molecular modeling and simulation techniques, was used to probe the effect of side chain structure on protein stability. Specific replacements at position 133 in T4 lysozyme included (i) leucine (wt), norvaline, ethylglycine, and alanine to measure the cost of stepwise removal of methyl groups from the hydrophobic core, (ii) norvaline and O-...
متن کاملUnnatural amino acids: better than the real things?
Considerable effort has been dedicated to the development of technology for the site-specific incorporation of unnatural amino acids into proteins, with nonsense codon suppression and expressed protein ligation emerging as two of the most promising methods. Recent research advances in which these methods have been applied to study protein function and mechanism are briefly highlighted, and the ...
متن کاملReversible biomechano-responsive surface based on green fluorescent protein genetically modified with unnatural amino acids.
GFP has been genetically modified at two specific positions of its molecular architecture. These modifications allow its covalent attachment onto PEG brushes grafted on functionalized silicone surfaces. The stretching of this material leads to a reversible decrease of the fluorescence intensity due to stretch-induced forces applying on GFP molecules.
