Abstract
Protein lipid modification involves the attachment of hydrophobic groups to proteins via ester, thioester, amide, or thioether linkages. In this review, the specific click chemical reactions that have been employed to study protein lipid modification and their use for specific labeling applications are first described. This is followed by an introduction to the different types of protein lipid modifications that occur in biology. Next, the roles of click chemistry in elucidating specific biological features including the identification of lipid-modified proteins, studies of their regulation, and their role in diseases are presented. A description of the use of protein-lipid modifying enzymes for specific labeling applications including protein immobilization, fluorescent labeling, nanostructure assembly, and the construction of protein-drug conjugates is presented next. Concluding remarks and future directions are presented in the final section.

Abstract
The copper-catalyzed azide/alkyne cycloaddition reaction (CuAAC) has emerged as the most useful "click" chemistry. Polymer science has profited enormously from CuAAC by its simplicity, ease, scope, applicability and efficiency. Basic principles of the CuAAC are reviewed with a focus on homogeneous and heterogeneous catalysts, ligands, anchimeric assistance, and basic chemical principles. Recent developments of ligand design and acceleration are discussed.

Abstract
Bioconjugation chemistry has been used to prepare modified biomolecules with functions beyond what nature intended. Central to these techniques is the development of highly efficient and selective bioconjugation reactions that operate under mild, biomolecule compatible conditions. Methods that form a nucleophile-sp2 carbon bond show promise for creating bioconjugates with new modifications, sometimes resulting in molecules with unparalleled functions. Here we outline and review sulfur, nitrogen, selenium, oxygen, and carbon arylative bioconjugation strategies and their applications to modify peptides, proteins, sugars, and nucleic acids.

Abstract
Protein labeling is enormously useful for characterization of protein function in live cells and study of the related cellular processes. Covalent labeling of protein using affinity conjugation confers stable and selective labeling of protein in cells. Affinity conjugation combines a specific ligand-protein interaction with a proximity-induced reaction to selectively label the protein of interest (POI) in the cell. Therefore, either a fluorogenic probe is directly introduced to the POI or a bioorthogonal group is incorporated to the POI, which is subsequently labeled with a fluorescent probe. Here, we describe a method for affinity conjugation of protein with a fluorogenic probe and a "tagging-then-labeling" approach by a combination of affinity conjugation with bioorthogonal reactions.

Abstract
Bioconjugates represent an emerging class of medicines, which offer therapeutic opportunities overtaking those of the individual components. Many novel bioconjugates have been explored in order to address various emerging medical needs. The last decade has witnessed the exponential growth of new site-selective bioconjugation techniques, however very few methods have made the way into human clinical trials. Here we discuss various applications of site-selective conjugation in biomedicines, including half-life extension, antibody-drug conjugates, conjugate vaccines, bispecific antibodies and cell therapy. The review is intended to highlight both the progress and challenges, and identify a potential roadmap to address the gap.

Abstract
Biomacromolecules offer complex and precise functions embedded in their monomer sequence such as enzymatic activity or specific interactions towards other molecules. Their informational content and capability to organize in higher ordered structures is superior to those of synthetic molecules. In comparison, synthetic polymers are easy to access even at large production scales and they are chemically more diverse. Solubilization, shielding against enzymatic degradation to more advanced functions like switchability or protein mimicry, etc., are accessible through the world of polymer chemistry. Bio-inspired hybrid materials consisting of peptides or proteins and synthetic polymers thereby combine the properties of both molecules to give rise to a new class of materials with unique characteristics and performance. To obtain well-defined bioconjugate materials, high yielding and site-specific as well as biorthogonal ligation techniques are mandatory. Since the first attempts of protein PEGylation in the 1970s and the concept of “click” chemistry arising in 2001, continuous progress in the field of peptide– and protein–polymer conjugate preparation has been gained. Herein, we provide an overview on ligation techniques to prepare functional bioconjugates published in the last decade, also referred to as “post-click” methods. Furthermore, chemoenzymatic approaches and biotransformation reactions used in peptide or protein modification, as well as highly site-specific and efficient reactions originated in synthetic macromolecular chemistry, which could potentially be adapted for bioconjugation, are presented. Finally, future perspectives for the preparation and application of bioconjugates at the interface between biology and synthetic materials are given.

Abstract
Over the years, there have been remarkable efforts in the development of selective protein labeling strategies. In this review, we deliver a comprehensive overview of the currently available bioorthogonal and chemoselective reactions. The ability to introduce bioorthogonal handles to proteins is essential to carry out bioorthogonal reactions for protein labeling in living systems. We therefore summarize the techniques that allow for site-specific "installation" of bioorthogonal handles into proteins. We also highlight the biological applications that have been achieved by selective chemical labeling of proteins.

Abstract
Attempts to identify the prenyl-proteome of cells or changes in prenylation following drug treatment have used 'clickable' alkyne-modified analogs of the lipid substrates farnesyl- and geranylgeranyl-diphosphate (FPP and GGPP). We characterized the reactivity of four alkyne-containing analogs of FPP with purified protein farnesyltransferase and a small library of dansylated peptides using an in vitro continuous spectrofluorimetric assay. These analogs alter prenylation specificity and reactivity suggesting that in vivo results obtained using these FPP analogs should be interpreted cautiously.

Abstract
Site-selective functionalization of complex molecules is one of the most significant challenges in chemistry. Typically, protecting groups or catalysts must be used to enable the selective modification of one site among many that are similarly reactive, and general strategies that selectively tune the local chemical environment around a target site are rare. Here, we show a four-amino-acid sequence (Phe-Cys-Pro-Phe), which we call the 'π-clamp', that tunes the reactivity of its cysteine thiol for site-selective conjugation with perfluoroaromatic reagents. We use the π-clamp to selectively modify one cysteine site in proteins containing multiple endogenous cysteine residues. These examples include antibodies and cysteine-based enzymes that would be difficult to modify selectively using standard cysteine-based methods. Antibodies modified using the π-clamp retained binding affinity to their targets, enabling the synthesis of site-specific antibody-drug conjugates for selective killing of HER2-positive breast cancer cells. The π-clamp is an unexpected approach to mediate site-selective chemistry and provides new avenues to modify biomolecules for research and therapeutics.

Abstract
Site-specific protein labeling is an important technique in protein chemistry and is used for diverse applications ranging from creating protein conjugates to protein immobilization. Enzymatic reactions, including protein prenylation, have been widely exploited as methods to accomplish site-specific labeling. Enzymatic prenylation is catalyzed by prenyltransferases, including protein farnesyltransferase (PFTase) and geranylgeranyltransferase type I (GGTase-I), both of which recognize C-terminal CaaX motifs with different specificities and transfer prenyl groups from isoprenoid diphosphates to their respective target proteins. A number of isoprenoid analogues containing bioorthogonal functional groups have been used to label proteins of interest via PFTase-catalyzed reaction. In this study, we sought to expand the scope of prenyltransferase-mediated protein labeling by exploring the utility of rat GGTase-I (rGGTase-I). First, the isoprenoid specificity of rGGTase-I was evaluated by screening eight different analogues and it was found that those with bulky moieties and longer backbone length were recognized by rGGTase-I more efficiently. Taking advantage of the different substrate specificities of rat PFTase (rPFTase) and rGGTase-I, we then developed a simultaneous dual labeling method to selectively label two different proteins by using isoprenoid analogue and CaaX substrate pairs that were specific to only one of the prenyltransferases. Using two model proteins, green fluorescent protein with a C-terminal CVLL sequence (GFP-CVLL) and red fluorescent protein with a C-terminal CVIA sequence (RFP-CVIA), we demonstrated that when incubated together with both prenyltransferases and the selected isoprenoid analogues, GFP-CVLL was specifically modified with a ketone-functionalized analogue by rGGTase-I and RFP-CVIA was selectively labeled with an alkyne-containing analogue by rPFTase. By switching the ketone-containing analogue to an azide-containing analogue, it was possible to create protein tail-to-tail dimers in a one-pot procedure through the copper(I)-catalyzed alkyne-azide cycloaddition (CuAAC) reaction. Overall, with the flexibility of using different isoprenoid analogues, this system greatly extends the utility of protein labeling using prenyltransferases.

Abstract
Site-specific modification of proteins is a major challenge in modern chemical biology due to the large number of reactive functional groups typically present in polypeptides. Because of its importance in biology and medicine, the development of methods for site-specific modification of proteins is an area of intense research. Selective protein modification procedures have been useful for oriented protein immobilization, for studies of naturally occurring post-translational modifications, for creating antibody–drug conjugates, for the introduction of fluorophores and other small molecules on to proteins, for examining protein structure, folding, dynamics, and protein–protein interactions, and for the preparation of protein–polymer conjugates. One of the most important approaches for protein labeling is to incorporate bioorthogonal functionalities into proteins at specific sites via enzymatic reactions. The incorporated tags then enable reactions that are chemoselective, whose functional groups not only are inert in biological media, but also do not occur natively in proteins or other macromolecules. This review article summarizes the enzymatic strategies, which enable site-specific functionalization of proteins with a variety of different functional groups. The enzymes covered in this review include formylglycine generating enzyme, sialyltransferases, phosphopantetheinyltransferases, O-GlcNAc post-translational modification, sortagging, transglutaminase, farnesyltransferase, biotin ligase, lipoic acid ligase, and N-myristoyltransferase.

Abstract
![]()
Protein farnesytransferase (PFTase)
catalyzes the farnesylation
of proteins with a carboxy-terminal tetrapeptide sequence denoted
as a Ca1a2X box. To explore the specificity
of this enzyme, an important therapeutic target, solid-phase peptide
synthesis in concert with a peptide inversion strategy was used to
prepare two libraries, each containing 380 peptides. The libraries
were screened using an alkyne-containing isoprenoid analogue followed
by click chemistry with biotin azide and subsequent visualization
with streptavidin-AP. Screening of the CVa2X and CCa2X libraries with Rattus norvegicus PFTase revealed reaction by many known recognition sequences as
well as numerous unknown ones. Some of the latter occur in the genomes
of bacteria and viruses and may be important for pathogenesis, suggesting
new targets for therapeutic intervention. Screening of the CVa2X library with alkyne-functionalized isoprenoid substrates
showed that those prepared from C10 or C15 precursors
gave similar results, whereas the analogue synthesized from a C5 unit gave a different pattern of reactivity. Lastly, the
substrate specificities of PFTases from three organisms (R. norvegicus, Saccharomyces cerevisiae, and Candida albicans) were compared
using CVa2X libraries. R. norvegicus PFTase was found to share more peptide substrates with S. cerevisiae PFTase than with C.
albicans PFTase. In general, this method is a highly
efficient strategy for rapidly probing the specificity of this important
enzyme.

Abstract
There is a growing library of functionalized non-natural substrates for the enzyme protein farnesyltransferase (PFTase). PFTase covalently attaches these functionalized non-natural substrates to proteins ending in the sequence CAAX, where C is a cysteine that becomes alkylated, A represents an aliphatic amino acid, and X is Ser, Met, Ala, or Gln. Reported substrates include a variety of functionalities that allow modified proteins to undergo subsequent bioconjugation reactions. To date the most common strategy used in this approach has been copper catalyzed azide-alkyne cycloaddition (CuAAC). While being fast and bioorthogonal CuAAC has limited use in live cell experiments due to copper's toxicity.(1) Here, we report the synthesis of trans-cyclooctene geranyl diphosphate. This substrate can be synthesized from geraniol in six steps and be enzymatically transferred to peptides and proteins that end in a CAAX sequence. Proteins and peptides site-specially modified with trans-cyclooctene geranyl diphosphate were subsequently targeted for further modification via tetrazine ligation. As tetrazine ligation is bioorthogonal, fast, and is contingent on ring strain rather than the addition of a copper catalyst, this labeling strategy should prove useful for labeling proteins where the presence of copper may hinder solubility or biological reactivity.

Abstract
Herein, a combination of microcontact printing of functionalized alkanethiols and site-specific modification of proteins is utilized to chemoselectively immobilize proteins onto gold surfaces, either by oxime- or copper-catalyzed alkyne-azide click chemistry. Two molecules capable of click reactions were synthesized, an aminooxy-functionalized alkanethiol and an azide-functionalized alkanethiol, and self-assembled monolayer (SAM) formation on gold was confirmed by IR spectroscopy. The alkanethiols were then individually patterned onto gold surfaces by microcontact printing. Site-specifically modified proteins-horse heart myoglobin (HHMb) containing an N-terminal α-oxoamide and a red fluorescent protein (mCherry-CVIA) with a C-terminal alkyne-were immobilized by incubation onto respective stamped functionalized alkanethiol patterns. Pattern formation was confirmed by fluorescence microscopy.

Abstract
The copper-catalyzed azide-alkyne cycloaddition (CuAAC) is one of the most broadly applicable and easy-to-handle reactions in the arsenal of organic chemistry. However, the mechanistic understanding of this reaction has lagged behind the plethora of its applications for a long time. As reagent mixtures of copper salts and additives are commonly used in CuAAC reactions, the structure of the catalytically active species itself has remained subject to speculation, which can be attributed to the multifaceted aggregation chemistry of copper(I) alkyne and acetylide complexes. Following an introductory section on common catalyst systems in CuAAC reactions, this review will highlight experimental and computational studies from early proposals to very recent and more sophisticated investigations, which deliver more detailed insights into the CuAAC's catalytic cycle and the species involved. As diverging mechanistic views are presented in articles, books and online resources, we intend to present the research efforts in this field during the past decade and finally give an up-to-date picture of the currently accepted dinuclear mechanism of CuAAC. Additionally, we hope to inspire research efforts on the development of molecularly defined copper(I) catalysts with defined structural characteristics, whose main advantage in contrast to the regularly used precatalyst reagent mixtures is twofold: on the one hand, the characteristics of molecularly defined, well soluble catalysts can be tuned according to the particular requirements of the experiment; on the other hand, the understanding of the CuAAC reaction mechanism can be further advanced by kinetic studies and the isolation and characterization of key intermediates.

Abstract
Site-specific chemical modification of proteins is important for many applications in biology and biotechnology. Recently, our laboratory and others have exploited the high specificity of the enzyme protein farnesyltransferase (PFTase) to site-specifically modify proteins through the use of alternative substrates that incorporate bioorthogonal functionality including azides and alkynes. In this study, we evaluate two aldehyde-containing molecules as substrates for PFTase and as reactants in both oxime and hydrazone formation. Using green fluorescent protein (GFP) as a model system, we demonstrate that the purified protein can be enzymatically modified with either analogue to yield aldehyde-functionalized proteins. Oxime or hydrazone formation was then employed to immobilize, fluorescently label, or PEGylate the resulting aldehyde-containing proteins. Immobilization via hydrazone formation was also shown to be reversible via transoximization with a fluorescent alkoxyamine. After characterizing this labeling strategy using pure protein, the specificity of the enzymatic process was used to selectively label GFP present in crude E. coli extract followed by capture of the aldehyde-modified protein using hydrazide-agarose. Subsequent incubation of the immobilized protein using a fluorescently labeled or PEGylated alkoxyamine resulted in the release of pure GFP containing the desired site-specific covalent modifications. This procedure was also employed to produce PEGylated glucose-dependent insulinotropic polypeptide (GIP), a protein with potential therapeutic activity for diabetes. Given the specificity of the PFTase-catalyzed reaction coupled with the ability to introduce a CAAX-box recognition sequence onto almost any protein, this method shows great potential as a general approach for selective immobilization and labeling of recombinant proteins present in crude cellular extract without prior purification. Beyond generating site-specifically modified proteins, this approach for polypeptide modification could be particularly useful for large-scale production of protein conjugates for therapeutic or industrial applications.

Abstract
Protein modification with isoprenoid lipids affects hundreds of signaling proteins in eukaryotic cells. Modification of isoprenoids with reporter groups is the main approach for the creation of probes for the analysis of protein prenylation in vitro and in vivo. Here, we describe a new strategy for the synthesis of functionalized phosphoisoprenoids that uses an aminederivatized isoprenoid scaffold as a starting point for the synthesis of functionalized phosphoisoprenoid libraries. This overcomes a long-standing problem in the field, where multistep synthesis had to be carried out for each individual isoprenoid analogue. The described approach enabled us to synthesize a range of new compounds, including two novel fluorescent isoprenoids that previously could not be generated by conventional means. The fluorescent probes that were developed using the described approach possess significant spectroscopic advantages to all previously generated fluorescent isoprenoid analogue. Using these analogues for flow cytometry and cell imaging, we analyzed the uptake of isoprenoids by mammalian cells and zebrafish embryos. Furthermore, we demonstrate that derivatization of the scaffold can be coupled in a one-pot reaction to enzymatic incorporation of the resulting isoprenoid group into proteins. This enables rapid evaluation of functional groups for compatibility with individual prenyltransferases and identification of the prenyltransferase specific substrates.

Abstract
Protein lipidation and lipid trafficking control many key biological functions in all kingdoms of life. The discovery of diverse lipid species and their covalent attachment to many proteins has revealed a complex and regulated network of membranes and lipidated proteins that are central to fundamental aspects of physiology and human disease. Given the complexity of lipid trafficking and the protein targeting mechanisms involved with membrane lipids, precise and sensitive methods are needed to monitor and identify these hydrophobic molecules in bacteria, yeast, and higher eukaryotes. Although many analytical methods have been developed for characterizing membrane lipids and covalently modified proteins, traditional reagents and approaches have limited sensitivity, do not faithfully report on the lipids of interest, or are not readily accessible. The invention of bioorthogonal ligation reactions, such as the Staudinger ligation and azide-alkyne cycloadditions, has provided new tools to address these limitations, and their use has begun to yield fresh insight into the biology of protein lipidation and lipid trafficking. In this Account, we discuss how these new bioorthogonal ligation reactions and lipid chemical reporters afford new opportunities for exploring the biology of lipid-modified proteins and lipid trafficking. Lipid chemical reporters from our laboratory and several other research groups have enabled improved detection and large-scale proteomic analysis of fatty-acylated and prenylated proteins. For example, fatty acid and isoprenoid chemical reporters in conjunction with bioorthogonal ligation methods have circumvented the limited sensitivity and hazards of radioactive analogues, allowing rapid and robust fluorescent detection of lipidated proteins in all organisms tested. These chemical tools have revealed alterations in protein lipidation in different cellular states and are beginning to provide unique insights in mechanisms of regulation. Notably, the purification of proteins labeled with lipid chemical reporters has allowed both the large-scale analysis of lipidated proteins as well as the discovery of new lipidated proteins involved in metabolism, gene expression, and innate immunity. Specific lipid reporters have also been developed to monitor the trafficking of soluble lipids; these species are enabling bioorthogonal imaging of membranes in cells and tissues. Future advances in bioorthogonal chemistry, specific lipid reporters, and spectroscopy should provide important new insight into the functional roles of lipidated proteins and membranes in biology.

Abstract
In the past decade, numerous chemical technologies have been developed to allow the site-specific post-translational modification of proteins. Traditionally covalent chemical protein modification has been accomplished by the attachment of synthetic groups to nucleophilic amino acids on protein surfaces. These chemistries, however, are rarely sufficiently selective to distinguish one residue within a literal sea of chemical functionality. One solution to this problem is to introduce a unique chemical handle into the target protein that is orthogonal to the remainder of the proteome. In practice, this handle can be a novel peptide sequence, which forms a 'tag' that is selectively and irreversibly modified by enzymes. Furthermore, if the enzymes can tolerate substrate analogs, it becomes possible to engineer chemically modified proteins in a site-specific fashion. This review details the significant progress in creating techniques for the chemoenzymatic generation of protein-small molecule constructs and provides examples of novel applications of these methodologies.

Abstract
The similarity ensemble approach (SEA) relates proteins based on the set-wise chemical similarity among their ligands. It can be used to rapidly search large compound databases and to build cross-target similarity maps. The emerging maps relate targets in ways that reveal relationships one might not recognize based on sequence or structural similarities alone. SEA has previously revealed cross talk between drugs acting primarily on G-protein coupled receptors (GPCRs). Here we used SEA to look for potential off-target inhibition of the enzyme protein farnesyltransferase (PFTase) by commercially available drugs. The inhibition of PFTase has profound consequences for oncogenesis, as well as a number of other diseases. In the present study, two commercial drugs, Loratadine and Miconazole, were identified as potential ligands for PFTase and subsequently confirmed as such experimentally. These results point toward the applicability of SEA for the prediction of not only GPCR-GPCR drug cross talk but also GPCR-enzyme and enzyme-enzyme drug cross talk.
