    Abstract Many amino acid-containing natural products are biosynthesized by large, multifunctional enzymes known as non-ribosomal peptide synthetases (NRPSs). Adenylation (A) domains in NRPSs are responsible for the incorporation of amino acid building blocks and can be considered as engineering domains; therefore, advanced techniques are required to not only rapidly verify expression and folding, but also accelerate the functional prediction of the A-domains in lysates from native and heterologous systems. We recently developed activity-based protein profiling (ABPP) of NRPSs that offers a simple and robust analytical platform for A-domains and provides insights into their enzyme-substrate specificity. In this chapter, we describe the design and synthesis of these ABPP probes and provide a summary of our work on the development of a series of protocols for labeling, visualizing, and analyzing endogenous NRPSs in complex biological systems.

    Abstract 4'-Phosphopantetheinylation is an essential posttranslational modification of the primary and secondary metabolic pathways in prokaryotes and eukaryotes. Several peptide-based natural products are biosynthesized by large, multifunctional enzymes known as nonribosomal peptide synthetases (NRPSs), responsible for producing virulence factors and many pharmaceuticals. The thiolation (T) domain serves as a covalent tether for substrates and intermediates in nonribosomal peptide biosynthesis and must be posttranslationally modified with a 4'-phosphopantetheinyl group. To detect 4'-phosphopantetheinylation of NRPS in bacterial proteomes, we developed a 5'-(vinylsulfonylaminodeoxy)adenosine scaffold with a clickable functionality, enabling effective chemical labeling of 4'-phosphopantethylated NRPSs. In this chapter, we describe the design and synthesis of an activity-based protein profiling probe and summarize our work toward developing a series of protocols for the labeling and visualization of 4'-phosphopantetheinylation of endogenous NRPSs in complex proteomes.

    Abstract Proteins in the cells are born (synthesized), work, and die (decomposed). In the life of a protein, its birth is obviously important, but how it dies is equally important in living organisms. Proteases secreted into the outside of cells are used to decompose the external proteins and the degradation products are taken as the nutrients. On the other hand, there are also proteases that decompose unnecessary or harmful proteins which are generated in the cells. In eukaryotes, a large enzyme complex called the proteasome is primarily responsible for degradation of such proteins. Bacteria, which are prokaryotes, have a similar system as the proteasome. We would like to explain the bacterial degradation system of proteins or the death of proteins, which is performed by ATP-dependent protease Clp, with a particular focus on the ClpXP complex, and with an aspect as a target for antibiotics against bacteria.

    Abstract Nonribosomal peptide synthetases (NRPSs) biosynthesize nonribosomal peptide (NRP) natural products, which belong to the most promising resources for drug discovery and development because of their wide range of therapeutic applications. The results of genetic, biochemical, and bioinformatics analyses have enhanced our understanding of the mechanisms of the NRPS machinery. A major goal in NRP biosynthesis is to reprogram the NRPS machinery to enable the biosynthetic production of designed peptides. Reprogramming strategies for the NRPS machinery have progressed considerably in recent years, thereby increasing the yields and generating modified peptides. Here, the recent progress in NRPS reprogramming and its application in peptide synthesis are described.

    Abstract Non-ribosomal peptide synthetases (NRPSs) biosynthesize many pharmaceuticals and virulence factors. The biosynthesis of these natural peptide products from biosynthetic gene clusters depends on complex regulations in bacteria. However, our current knowledge of NRPSs is based on enzymological studies using full NRPS systems and/or a single NRPS domain in heterologous hosts. Chemical and/or biochemical strategies to capture the endogenous activities of NRPSs facilitate studies on NRPS cell biology in bacterial cells. Here, we describe a chemical scaffold for the rapid and selective photoaffinity labelling of NRPSs in purified systems, crude biological samples and living bacterial cells. We synthesized photoaffinity labelling probes coupled with 5'-

    Abstract Aggressive cancers, such as triple-negative breast cancer (TNBC), are mostly fatal because of their potential to metastasize to distant organs. Cancer cells acquire various abilities to metastasize, including resistance to anoikis, an apoptotic cell death induced by loss of anchorage to the extracellular matrix. Transcriptional coactivator with PDZ binding motif (TAZ) and Yes-associated protein (YAP), the downstream effectors of the Hippo pathway, regulate cell- and tissue-level architectures by responding to mechanical microenvironments of cells, including the cell-extracellular matrix interaction. The Hippo pathway is frequently disrupted in cancer cells, and TAZ and YAP are irrelevantly activated, potentially resulting in anchorage-independent survival/proliferation of cancer cells and metastatic progression. The study aims to investigate the roles of TAZ and YAP in anoikis resistance in basal-like (BL) TNBC cells, which comprise a major subtype (>70%) of TNBC. We found that TAZ and YAP had nonredundant roles in anchorage-independent cancer cell survival or anoikis resistance. Particularly, TAZ was indispensable for anoikis resistance in BL-TNBC cells but not for survival of non-transformed mammary epithelial cells (MECs). In contrast, YAP, a paralog of TAZ, was indispensable for survival of both non-transformed MECs and cancer cells. Therefore, TAZ might be a preferable therapeutic target against dissemination of aggressive cancer cells without killing normal cells. Interestingly, TAZ was abnormally stabilized in BL-TNBC cells under non-adherent conditions, which promoted anoikis resistance. Furthermore, OTUB1, a deubiquitinating enzyme, was responsible for the stabilization of TAZ in detached BL-TNBC cells. Importantly, simultaneous high expression of TAZ and OTUB1 was associated with poor prognosis in BC. Thus, OTUB1 has emerged as a potentially druggable target. Successful inhibition of OTUB1 enzymatic activity is expected to downregulate TAZ and eventually prevents metastasis of aggressive cancers, such as BL-TNBC.
