Abstract
The reversible attachment of ubiquitin (Ub) and ubiquitin like modifiers (Ubls) to proteins are crucial post-translational modifications (PTMs) for many cellular processes. Not only do cells possess hundreds of ligases to mediate substrate specific modification with Ub and Ubls, but they also have a repertoire of more than 100 dedicated enzymes for the specific removal of ubiquitin (Deubiquitinases or DUBs) and Ubl modifications (Ubl-specific proteases or ULPs). Over the past two decades, there has been significant progress in our understanding of how DUBs and ULPs function at a molecular level and many novel DUBs and ULPs, including several new DUB classes, have been identified. Here, the development of chemical tools that can bind and trap active DUBs has played a key role. Since the introduction of the first activity-based probe for DUBs in 1986, several innovations have led to the development of more sophisticated tools to study DUBs and ULPs. In this review we discuss how chemical biology has led to the development of activity-based probes and substrates that have been invaluable to the study of DUBs and ULPs. We summarise our currently available toolbox, highlight the main achievements and give an outlook of how these tools may be applied to gain a better understanding of the regulatory mechanisms of DUBs and ULPs.

Abstract
This mini-review will cover the various chemical biology approaches employed to prepare and modulate ubiquitin chains and the ubiquitin-proteasome system. Emphasis will be given to the biochemistry and chemical biology of poly-ubiquitin chain preparation as a tool to elucidate its roles in biological systems as well as the hijacking of the ubiquitin proteasome system using heterobifunctional compounds to induce intracellular ubiquitination.

Abstract
Ubiquitination is a versatile posttranslational modification that elicits signaling roles to impact on various cellular processes and disease states. The versatility is a result of the complexity of ubiquitin conjugates, ranging from a single ubiquitin monomer to polymers with different length and linkage types. Recent studies have revealed the abundant existence of branched ubiquitin chains in which one ubiquitin molecule is connected to two or more ubiquitin moieties in the same ubiquitin polymer. Compared to the homotypic ubiquitin chain, the branched chain is recognized or processed differently by readers and erasers of the ubiquitin system, respectively, resulting in a qualitative or quantitative alteration of the functional output. Furthermore, certain types of branched ubiquitination are induced by cellular stresses, implicating their important physiological role in stress adaption. In addition, the current chemical methodologies of solid phase peptide synthesis and expanding genetic code approach have been developed to synthesize different architectures of branched ubiquitin chains. The synthesized branched ubiquitin chains have shown their significance in understanding the topologies and binding partners of the branched chains. Here, we discuss the recent progresses on the detection, functional characterization and synthesis of branched ubiquitin chains as well as the future perspectives of this emerging field.
