BACKGROUND Analysis of global changes in gene transcription and translation by systems-based genomics and proteomics approaches provides only indirect information about protein function. In many cases, enzymatic activity fails to correlate with transcription or translation levels. Therefore, a direct method for broadly determining activities of an entire class of enzymes on a genome-wide scale would be of great utility. RESULTS We have engineered chemical probes that can be used to broadly… 
Activity Profiling of Papain-Like Cysteine Proteases in Plants1
TLDR
Together, these results demonstrate that this technology can identify differentially activated proteases and/or characterize the activity of a particular protease within complex mixtures.

TLDR
Preliminary results involving the solid-phase synthesis of cathepsin B-specific ABPs based on the E-64 scaffold and development of a method that would allow facile attachment of diverse peptide sequences on both sides of the epoxide moiety are reported.
Activity-based probes for the proteomic profiling of metalloproteases.
TLDR
It is demonstrated that MPs can display overlapping inhibitor sensitivities despite lacking sequence homology and the need to evaluate MP inhibitors broadly across this enzyme class to develop agents with suitable target selectivities in vivo is stressed.
Activity‐Based Protein Profiling for Type I Methionine Aminopeptidase by Using Photo‐Affinity Trimodular Probes
TLDR
An advanced technique is introduced, “CC-ABPP”, in which the reporter tag is attached to the probe by the bio-orthogonal copper(I)-catalyzed azide and alkyne cycloaddition reaction following covalent labeling of the protein target, and a similar strategy for the design and chemical synthesis of a trimodular affinity probe is reported.
In-cell Selectivity Profiling of Serine Protease Inhibitors by Activity-based Proteomics*S
TLDR
This novel ABP was shown to label the active site of several serine proteases with greater efficiency than a previously reported fluorophosphonate probe and open new perspectives for safety profiling studies in uncovering potential cellular “side effects” of drugs (unanticipated off-target inhibition or activation) that may be overlooked by standard selectivity profiling methods.
Chemical proteomics applied to target identification and drug discovery.
TLDR
A new research area has been created to begin to address protein function at the level of regulation of enzyme activity, which makes use of small molecules that can covalently attach to catalytic residues in an enzyme active site and has the potential to accelerate the discovery of new drug targets.
From covalent glycosidase inhibitors to activity-based glycosidase probes.
TLDR
This concept presents the current progress and future directions in the design of activity-based probes targeting retaining Glycosidases, enzymes that employ a double displacement mechanism in the hydrolysis of glycosidic bonds with overall retention.
Small Molecules as Versatile Tools for Activity-Based Protein Profiling Experiments
TLDR
In combination with applications for competitive inhibitor screening and molecular imaging, ABPP represents a key technology not only important for the functional characterization of enzyme activity but also indispensable for drug discovery programs.
Protease proteomics: revealing protease in vivo functions using systems biology approaches.
TLDR
Methods to assess protease expression at the messenger RNA level using DNA microarrays and at the protein level using mass spectrometry-based proteomics are described and methods to reveal and quantify the activity state of proteases and to identify their biological substrates are reviewed.
Applications of Copper-Catalyzed Click Chemistry in Activity-Based Protein Profiling
TLDR
Recent examples of CuAAC in ABPP are summarized to illustrate the contribution of bioorthogonal chemistry to advancing discoveries in this field.

Activity-based protein profiling: the serine hydrolases.
TLDR
The chemical synthesis and utility of an active-site directed probe for visualizing dynamics in the expression and function of an entire enzyme family, the serine hydrolases, is described and it is shown that FP-biotin labels these proteins in an activity-dependent manner that can be followed kinetically.
Selective targeting of lysosomal cysteine proteases with radiolabeled electrophilic substrate analogs.
TLDR
These probes are used to show that cathepsin activity is regulated in tumor tissues and during differentiation of placental-derived cytotrophoblasts to invasive cells required for establishing blood circulation in a developing embryo.
Substrate binding and sequence preference of the proteasome revealed by active-site-directed affinity probes.
TLDR
These studies indicate that it is possible to generate inhibitors that are largely specific for individual beta subunits of the proteasome by modulation of the P4 and carboxy-terminal vinyl sulfone moieties.
Structural basis of inhibition of cysteine proteases by E-64 and its derivatives.
This paper focuses on the inhibitory mechanism of E-64 and its derivatives (epoxysuccinyl-based inhibitors) with some cysteine proteases, based on the binding modes observed in the x-ray crystal
Covalent modification of the active site threonine of proteasomal beta subunits and the Escherichia coli homolog HslV by a new class of inhibitors.
TLDR
125I-NIP-L3VS covalently modifies the HSlV subunit of the Escherichia coli protease complex HslV/HslU, a reaction that requires ATP, and supports a catalytic mechanism shared with that of the eukaryotic proteasome.
Methionine aminopeptidase (type 2) is the common target for angiogenesis inhibitors AGM-1470 and ovalicin.
TLDR
This finding suggests that MetAP2 may play a critical role in the proliferation of endothelial cells and may serve as a promising target for the development of new anti-angiogenic drugs.
Structure of rat procathepsin B: model for inhibition of cysteine protease activity by the proregion.
TLDR
The structure of procathepsin B provides the first insight into the mode of interaction between a mature cysteine protease from the papain superfamily and its prosegment, and suggests a novel strategy for inhibitor design.
Molecular cloning and expression of human alveolar macrophage cathepsin S, an elastinolytic cysteine protease.
TLDR
The data establish that human macrophages express at least two cysteine proteases with elastinolytic activity, and the relatively broad pH range of human cathepsin S activity suggests this enzyme may contribute to the contact-dependent elastase activity of live human alveolar macrophage.
Human and mouse proteomic databases: novel resources in the protein universe
TLDR
The problems one faces when using powerful proteomic technology to study heterogeneous tissue and tumor biopsies are discussed, and the importance of building comprehensive databases that contain a critical mass of information for both known and novel proteins in normal and disease conditions are emphasized.
Peptidyl fluoromethyl ketones as thiol protease inhibitors.
TLDR
F fluoromethyl ketone derivatives of peptides are considerably less reactive to nucleophiles such as the thiol group of glutathione, than chlorometHyl ketones and, therefore, this new class of inhibitors may provoke fewer side reactions when used in biological studies.
