Abstract
HUH-tags have emerged as versatile fusion partners that mediate sequence specific protein-ssDNA bioconjugation through a simple and efficient reaction. Here we present HUHgle, a python-based interactive tool for the visualization, design, and optimization of substrates for HUH-tag mediated covalent labeling of proteins of interest with ssDNA substrates of interest. HUHgle streamlines design processes by integrating an intuitive plotting interface with a search function capable of predicting and displaying protein-ssDNA bioconjugate formation efficiency and specificity in proposed HUH-tag/ssDNA sequence combinations. Validation demonstrates that HUHgle accurately predicts product formation of HUH-tag mediated bioconjugation for single- and orthogonal-labeling reactions. In order to maximize the accessibility and utility of HUHgle, we have implemented it as a user-friendly Google Colab notebook which facilitates broad use of this tool, regardless of coding expertise.

Abstract
Engineered macromolecules offer compelling means for the therapy of conventionally undruggable interactions in human disease. However, their efficacy is limited by barriers to tissue and intracellular delivery. Inspired by recent advances in molecular barcoding and evolution, we developed BarcodeBabel, a generalized method for the design of libraries of peptide barcodes suitable for high-throughput mass spectrometry proteomics. Combined with PeptideBabel, a Monte Carlo sampling algorithm for the design of peptides with evolvable physicochemical properties and sequence complexity, we developed a barcoded library of cell penetrating peptides (CPPs) with distinct physicochemical features. Using quantitative targeted mass spectrometry, we identified CPPS with improved nuclear and cytoplasmic delivery exceeding hundreds of millions of molecules per human cell while maintaining minimal membrane disruption and negligible toxicity in vitro. These studies provide a proof of concept for peptide barcoding as a homogeneous high-throughput method for macromolecular screening and delivery. BarcodeBabel and PeptideBabel are available open-source from https://github.com/kentsisresearchgroup/.

Abstract
The functionalization of proteins with DNA through the formation of covalent bonds enables a wide range of biotechnology advancements. For example, single-molecule analytical methods rely on bioconjugated DNA as elastic biolinkers for protein immobilization. Labeling proteins with DNA enables facile protein identification, as well as spatial and temporal organization and control of protein within DNA-protein networks. Bioconjugation reactions can target native, engineered, and non-canonical amino acids (NCAAs) within proteins. In addition, further protein engineering via the incorporation of peptide tags and self-labeling proteins can also be used for conjugation reactions. The selection of techniques will depend on application requirements such as yield, selectivity, conjugation position, potential for steric hindrance, cost, commercial availability, and potential impact on protein function.

Abstract
Phage display links the phenotype of displayed polypeptides with the DNA sequence in the phage genome and offers a universal method for the discovery of proteins with novel properties. However, the display of large multisubunit proteins on phages remains a challenge. A majority of protein display systems are based on monovalent phagemid constructs, but methods for the robust display of multiple copies of large proteins are scarce. Here, we describe a DNA-encoded display of a ∼ 200 kDa tetrameric l-asparaginase protein on M13 and fd phages produced by ligation of SpyCatcher-Asparaginase fusion (ScA) and PEGylated-ScA (PEG-ScA) to barcoded phage clones displaying SpyTag peptide. Starting from the SpyTag display on p3 or p8 coat proteins yielded constructs with five copies of ScA displayed on p3 (ScA-p3), ∼100 copies of ScA on p8 protein (ScA-p8) and ∼300 copies of PEG-ScA on p8 protein (PEG-ScA-p8). Display constructs of different valencies and chemical modifications on protein (e.g., PEGylation) can be injected into mice and analyzed by deep sequencing of the DNA barcodes associated with phage clones. In these multiplexed studies, we observed a density and protein-dependent clearance rate in vivo. Our observations link the absence of PEGylation and increase in density of the displayed protein with the increased rate of the endocytosis by cells in vivo. In conclusion, we demonstrate that a multivalent display of l-asparaginase on phages could be used to study the circulation life of this protein in vivo, and such an approach opens the possibility to use DNA sequencing to investigate multiplexed libraries of other multisubunit proteins in vivo.

Abstract
Pathogenic autoreactive antibodies that may be associated with life-threatening coronavirus disease 2019 (COVID-19) remain to be identified. Here, we show that self-assembled genome-scale libraries of full-length proteins covalently coupled to unique DNA barcodes for analysis by sequencing can be used for the unbiased identification of autoreactive antibodies in plasma samples. By screening 11,076 DNA-barcoded proteins expressed from a sequence-verified human ORFeome library, the method, which we named MIPSA (for Molecular Indexing of Proteins by Self-Assembly), allowed us to detect circulating neutralizing type-I and type-III interferon (IFN) autoantibodies in five plasma samples from 55 patients with life-threatening COVID-19. In addition to identifying neutralizing type-I IFN-α and IFN-ω autoantibodies and other previously known autoreactive antibodies in patient plasma, MIPSA enabled the detection of as yet unidentified neutralizing type-III anti-IFN-λ3 autoantibodies that were not seen in healthy plasma samples or in convalescent plasma from ten non-hospitalized individuals with COVID-19. The low cost and simple workflow of MIPSA will facilitate unbiased high-throughput analyses of protein-antibody, protein-protein and protein-small-molecule interactions.

Abstract
A large collection of unique molecular barcodes is useful in the simultaneous sensing or screening of molecular analytes. Though the sequence of DNA has been widely applied to encode for molecular barcodes, decoding of these barcodes is normally assisted by sequencing. We here demonstrate a barcode system based solely on self-assembly of synthetic nucleic acids and direct nanopore decoding. Each molecular barcode is composed of "n" distinct information nodes in a non-binary manner and can be sequentially scanned and decoded by a Mycobacterium smegmatis porin A (MspA) nanopore. Nanopore events containing step-shaped features were consistently reported. 14 unique information nodes were developed which in principle could encode for 14n unique molecular barcodes in a barcode containing "n" information nodes. These barcode probes were adapted to detect different antibody proteins or cancer-related microRNAs, suggesting their immediate application in a wide variety of sensing applications.

Abstract
The genome in a eukaryotic cell is packaged into chromatin and regulated by chromatin-binding and chromatin-modifying factors. Many of these factors and their complexes have been identified before, but how each genomic locus interacts with its surrounding proteins in the nucleus over time and in changing conditions remains poorly described. Measuring protein-DNA interactions at a specific locus in the genome is challenging and current techniques such as capture of a locus followed by mass spectrometry require high levels of enrichment. Epi-Decoder, a method developed in budding yeast, enables systematic decoding of the proteome of a single genomic locus of interest without the need for locus enrichment. Instead, Epi-Decoder uses massive parallel chromatin immunoprecipitation of tagged proteins combined with barcoding a genomic locus and counting of coimmunoprecipitated barcodes by DNA sequencing (TAG-ChIP-Barcode-Seq). In this scenario, DNA barcode counts serve as a quantitative readout for protein binding of each tagged protein to the barcoded locus. Epi-Decoder can be applied to determine the protein-DNA interactions at a wide range of genomic loci, such as coding genes, noncoding genes, and intergenic regions. Furthermore, Epi-Decoder provides the option to study protein-DNA interactions upon changing cellular and/or genetic conditions. In this protocol, we describe in detail how to construct Epi-Decoder libraries and how to perform an Epi-Decoder analysis.

Abstract
Templated chemistry offers the prospect of addressing specificity challenges occurring in bioconjugation reactions. Here, we show two peptide-templated amide-bond forming reactions that enable the concurrent labelling of two different membrane proteins with two different peptide nucleic acid (PNA) barcodes. The reaction system is based on the mutually selective coiled coil interaction between two thioester-linked PNA–peptide conjugates and two cysteine peptides serving as genetically encoded peptide tags. Orthogonal coiled coil templated covalent labelling is highly specific, quantitative and proceeds within a minute. To demonstrate the usefulness, we evaluated receptor internalisation of two membranous receptors EGFR (epidermal growth factor) and ErbB2 (epidermal growth factor receptor 2) by first staining PNA-tagged proteins with fluorophore–DNA conjugates and then erasing signals from non-internalized receptors via toehold-mediated strand displacement. A pair of orthogonal coiled coils templates highly specific live cell bioconjugation of two different proteins. PNA tagging and hybridisation with fluorophore–DNA reporters enables rapid dual receptor internalisation analysis of EGFR and ErbB2.![]()

Abstract
Understanding how genotypes map onto phenotypes, fitness, and eventually organisms is arguably the next major missing piece in a fully predictive theory of evolution. We refer to this generally as the problem of the genotype-phenotype map. Though we are still far from achieving a complete picture of these relationships, our current understanding of simpler questions, such as the structure induced in the space of genotypes by sequences mapped to molecular structures, has revealed important facts that deeply affect the dynamical description of evolutionary processes. Empirical evidence supporting the fundamental relevance of features such as phenotypic bias is mounting as well, while the synthesis of conceptual and experimental progress leads to questioning current assumptions on the nature of evolutionary dynamics-cancer progression models or synthetic biology approaches being notable examples. This work delves with a critical and constructive attitude into our current knowledge of how genotypes map onto molecular phenotypes and organismal functions, and discusses theoretical and empirical avenues to broaden and improve this comprehension. As a final goal, this community should aim at deriving an updated picture of evolutionary processes soundly relying on the structural properties of genotype spaces, as revealed by modern techniques of molecular and functional analysis.

Abstract
We report a series of 2'-deoxyribonucleoside triphosphates bearing dicarba-nido-undecaborate ([C2B9H11]1-), [3,3'-iron-bis(1,2-dicarbollide)]- (FESAN, [Fe(C2B9H11)2]2-) or [3,3'-cobalt-bis(1,2-dicarbollide)]- (COSAN, [Co(C2B9H11)2]2-) groups prepared either through the Sonogashira cross-coupling or the CuAAC click reaction. The modified dNXTPs were substrates for KOD XL DNA polymerase in enzymatic synthesis of modified DNA through primer extension (PEX). The nido-carborane- and FESAN-modified nucleotides gave analytically useful oxidation signals in square-wave voltammetry and were used for redox labeling of DNA. The redox-modified DNA probes were prepared by PEX using tailed primers and were hybridized to electrode (gold or glassy carbon) containing capture oligonucleotides. The combination of nido-carborane- and FESAN-linked nucleotides with 7-ferrocenylethynyl-7-deaza-dATP and 7-deaza-dGTP allowed polymerase synthesis of DNA fully modified at all four nucleobases, and each of the redox labels gave four differentiable and ratiometric signals in voltammetry. Thus, the combination of these four redox labels constitutes the first fully orthogonal redox coding of all four canonical nucleobases, which can be used for determination of nucleobase composition of short DNA stretches in one simple PEX experiment with electrochemical readout.

Abstract
Unbiased antibody profiling can identify the targets of an immune reaction. A number of likely pathogenic autoreactive antibodies have been associated with life-threatening SARS-CoV-2 infection; yet, many additional autoantibodies likely remain unknown. Here we present Molecular Indexing of Proteins by Self Assembly (MIPSA), a technique that produces ORFeome-scale libraries of proteins covalently coupled to uniquely identifying DNA barcodes for analysis by sequencing. We used MIPSA to profile circulating autoantibodies from 55 patients with severe COVID-19 against 11,076 DNA-barcoded proteins of the human ORFeome library. MIPSA identified previously known autoreactivities, and also detected undescribed neutralizing interferon lambda 3 (IFN-λ3) autoantibodies. At-risk individuals with anti- IFN-λ3 antibodies may benefit from interferon supplementation therapies, such as those currently undergoing clinical evaluation.

Abstract
Replication initiator proteins (Reps) from the HUH-endonuclease superfamily process specific single-stranded DNA (ssDNA) sequences to initiate rolling circle/hairpin replication in viruses, such as crop ravaging geminiviruses and human disease causing parvoviruses. In biotechnology contexts, Reps are the basis for HUH-tag bioconjugation and a critical adeno-associated virus genome integration tool. We solved the first co-crystal structures of Reps complexed to ssDNA, revealing a key motif for conferring sequence specificity and for anchoring a bent DNA architecture. In combination, we developed a deep sequencing cleavage assay, termed HUH-seq, to interrogate subtleties in Rep specificity and demonstrate how differences can be exploited for multiplexed HUH-tagging. Together, our insights allowed engineering of only four amino acids in a Rep chimera to predictably alter sequence specificity. These results have important implications for modulating viral infections, developing Rep-based genomic integration tools, and enabling massively parallel HUH-tag barcoding and bioconjugation applications.

Abstract
Research at the biological-material interface often has translation in mind, with applications in medical implants, drug delivery, and regenerative medicine. While the clinical impact of this research is undeniable, a clearer picture of the in vivo behavior of materials is needed to address longstanding limitations in performance and function. Advances in chemical biology and biotechnology have propelled our understanding of how small molecules and biologics behave in living systems. Adapting these techniques to the study of synthetic materials, enabled by modern polymer chemistry, will bring molecular resolution to biological-material interactions and guide the development of next-generation biomaterials for therapeutic and diagnostic applications.

Abstract
Hedgehog (Hh) precursor proteins contain an autoprocessing domain called HhC whose native function is protein cleavage and C-terminal glycine sterylation. The transformation catalyzed by HhC occurs in cis from a precursor protein and exhibits wide tolerance toward both sterol and protein substrates. Here, we repurpose HhC as a 1:1 protein-nucleic acid ligase, with the sterol serving as a molecular linker. A procedure is described for preparing HhC-active sterylated DNA, called steramers, using aqueous compatible chemistry and commercial reagents. Steramers have KM values of 7-11 μM and reaction t1/2 values of ∼10 min. Modularity of the HhC/steramer method is demonstrated using four different proteins along with structured and unstructured sterylated nucleic acids. The resulting protein-DNA conjugates retain the native solution properties and biochemical function. Unlike self-tagging domains, HhC does not remain fused to the conjugate; rather, enzymatic activity is mechanistically coupled to conjugate release. That unique feature of HhC, coupled with efficient kinetics and substrate tolerance, may ease access and open new applications for these suprabiological chimeras.

Identification of dual histone modification-binding protein interaction by combining mass spectrometry and isothermal titration calorimetric analysis. J Adv Res 2019; 22:35-46.

Abstract
The interaction between combinatorial histone modifications and tandem-domain reader proteins was identified. Four tandem-domain proteins (BPTF-PB, CBP-BP, TRIM24-PB, TAF1-BB) could read the peptides with dual-modifications. The binding affinities were detected by isothermal titration calorimetry. The interaction between BPTF-PB and peptides with PTMs is the strongest. The binding proteins to the tandem-domains were quantified. 78 enriched proteins were further characterized. The molecule network of “histone modification-reader-binding proteins” was analyzed.
Histone posttranslational modifications (HPTMs) play important roles in eukaryotic transcriptional regulation. Recently, it has been suggested that combinatorial modification codes that comprise two or more HPTMs can recruit readers of HPTMs, performing complex regulation of gene expression. However, the characterization of the multiplex interactions remains challenging, especially for the molecular network of histone PTMs, readers and binding complexes. Here, we developed an integrated method that combines a peptide library, affinity enrichment, mass spectrometry (MS) and bioinformatics analysis for the identification of the interaction between HPTMs and their binding proteins. Five tandem-domain-reader proteins (BPTF, CBP, TAF1, TRIM24 and TRIM33) were designed and prepared as the enriched probes, and a group of histone peptides with multiple PTMs were synthesized as the target peptide library. First, the domain probes were used to pull down the PTM peptides from the library, and then the resulting product was characterized by MS. The binding interactions between PTM peptides and domains were further validated and measured by isothermal titration calorimetry analysis (ITC). Meanwhile, the binding proteins were enriched by domain probes and identified by HPLC-MS/MS. The interaction network of histone PTMs-readers-binding complexes was finally analyzed via informatics tools. Our results showed that the integrated approach combining MS analysis with ITC assay enables us to understand the interaction between the combinatorial HPTMs and reading domains. The identified network of “HPTMs-reader proteins-binding complexes” provided potential clues to reveal HPTM functions and their regulatory mechanisms.

Abstract
A longstanding challenge in quantitative analysis is the relationship between a sensor's dynamic range and a background: the response range must align with the target's background value. If this condition is not met, a reliable measurement is impossible. The requirement is especially critical for sensing systems displaying sharp responses. In this work, we have solved the problem of response range/background misalignment via design of sensing systems that adjust their response to actual unknown backgrounds. The sensing systems are based on nucleic acid scaffolds: due to an intrinsic trait of multidimensional tunability, the sensors can assess the actual background and adjust response range accordingly. We established a general methodology and demonstrated, as a proof-of-concept, a practically meaningful example of detecting very small changes in proton concentrations over unknown aqueous backgrounds using a DNA i-motif sensor. Owing to multidimensional tunability of a DNA i-motif, this sensor could reliably measure changes in proton concentration that are 3 orders of magnitude below currently available methodologies.

Abstract
Isocyanide multicomponent reactions play a prominent role in drug discovery. This chemistry has hardly been investigated for compatibility with DNA-encoded combinatorial synthesis. The Ugi, Ugi-azide, and Groebke-Blackburn-Bienaymé reactions are well-tolerated by DNA on the solid phase and show a broad scope. However, an oxadiazole-forming variant of the Ugi reaction caused DNA depurination, requiring a more stable hexathymidine DNA for encoded library synthesis. Cheminformatic analysis revealed that isocyanide multicomponent-reaction-based encoded libraries cover a diverse chemical space.
