Membrane labeling and immobilization via copper-free click chemistry.
نویسندگان
چکیده
Copper-free click chemistry was employed to derivatize membrane bilayers. This approach uses an azido-lipid conjugate presented on liposomes, which can be labeled in bioorthogonal fashion via cyclooctyne-tagged reagents. An immobilization-based approach using streptavidin-coated microplates was exploited to evaluate membrane derivatization.

Specific labeling of zinc finger proteins using noncanonical amino acids and copper-free click chemistry.
Zinc finger proteins (ZFPs) play a key role in transcriptional regulation and serve as invaluable tools for gene modification and genetic engineering. Development of efficient strategies for labeling metalloproteins such as ZFPs is essential for understanding and controlling biological processes. In this work, we engineered ZFPs containing cysteine-histidine (Cys2-His2) motifs by metabolic inco...
متن کاملA click chemistry approach to site-specific immobilization of a small laccase enables efficient direct electron transfer in a biocathode.
Controlled orientation of a small laccase on a multi-walled carbon nanotube electrode was achieved via copper-free click chemistry mediated immobilization. Modification of the enzyme was limited to only the tethering site and involved the genetic incorporation of the unnatural amino acid 4-azido-L-phenylalanine (AzF). This approach enabled efficient direct electron transfer.
متن کاملHigh density orthogonal surface immobilization via photoactivated copper-free click chemistry.
Surfaces containing reactive ester polymer brushes were functionalized with cyclopropenone-masked dibenzocyclooctynes for the light activated immobilization of azides using catalyst-free click chemistry. The photodecarbonylation reaction in the amorphous brush layer is first order for the first 45 s with a rate constant of 0.022 s(-1). The catalyst-free cycloaddition of surface bound dibeznocyc...
متن کاملSite‐Specific Immobilization of the Peptidoglycan Synthase PBP1B on a Surface Plasmon Resonance Chip Surface
Surface plasmon resonance (SPR) is one of the most powerful label-free methods to determine the kinetic parameters of molecular interactions in real time and in a highly sensitive way. Penicillin-binding proteins (PBPs) are peptidoglycan synthesis enzymes present in most bacteria. Established protocols to analyze interactions of PBPs by SPR involve immobilization to an ampicillin-coated chip su...
متن کاملNucleotidyl transferase assisted DNA labeling with different click chemistries.
Here, we present a simple, modular and efficient strategy that allows the 3'-terminal labeling of DNA, regardless of whether it has been chemically or enzymatically synthesized or isolated from natural sources. We first incorporate a range of modified nucleotides at the 3'-terminus, using terminal deoxynucleotidyl transferase. In the second step, we convert the incorporated nucleotides, using e...
