Abstract
Neurodegeneration is characterized by a disturbance in neurotransmitter-mediated signaling pathways. Recent studies have highlighted the significant role of transition metal ions, including Cu(i/ii), Zn(ii), and Fe(ii/iii), in neurotransmission, thereby making the coordination chemistry of neurotransmitters a growing field of interest in understanding signal dysfunction. This review outlines the physiological functions of transition metal ions and neurotransmitters, with the metal-binding properties of small molecule-based neurotransmitters and neuropeptides. Additionally, we discuss the structural and conformational changes of neurotransmitters induced by redox-active metal ions, such as Cu(i/ii) and Fe(ii/iii), and briefly describe the outcomes arising from their oxidation, polymerization, and aggregation. These observations have important implications for neurodegeneration and emphasize the need for further research to develop potential therapeutic strategies.

Novel p.G250A Mutation Associated with Chronic Pancreatitis Highlights Misfolding-Prone Region in Carboxypeptidase A1 (CPA1). Int J Mol Sci 2022; 23:ijms232415463.

Abstract
Inborn mutations in the digestive protease carboxypeptidase A1 (CPA1) gene may be associated with hereditary and idiopathic chronic pancreatitis (CP). Pathogenic mutations, such as p.N256K, cause intracellular retention and reduced secretion of CPA1, accompanied by endoplasmic reticulum (ER) stress, suggesting that mutation-induced misfolding underlies the phenotype. Here, we report the novel p.G250A CPA1 mutation found in a young patient with CP. Functional properties of the p.G250A mutation were identical to those of the p.N256K mutation, confirming its pathogenic nature. We noted that both mutations are in a catalytically important loop of CPA1 that is stabilized by the Cys248-Cys271 disulfide bond. Mutation of either or both Cys residues to Ala resulted in misfolding, as judged by the loss of CPA1 secretion and intracellular retention. We re-analyzed seven previously reported CPA1 mutations that affect this loop and found that all exhibited reduced secretion and caused ER stress of varying degrees. The magnitude of ER stress was proportional to the secretion defect. Replacing the naturally occurring mutations with Ala (e.g., p.V251A for p.V251M) restored secretion, with the notable exception of p.N256A. We conclude that the disulfide-stabilized loop of CPA1 is prone to mutation-induced misfolding, in most cases due to the disruptive nature of the newly introduced side chain. We propose that disease-causing CPA1 mutations exhibit abolished or markedly reduced secretion with pronounced ER stress, whereas CPA1 mutations with milder misfolding phenotypes may be associated with lower disease risk or may not be pathogenic at all.

Abstract
Activity-based probes enable discrimination between the active enzyme and its inactive or inactivated counterparts. Since metalloproteases catalysis is non-covalent, activity-based probes targeting them have been systematically developed by decorating reversible inhibitors with photo-crosslinkers. By exploiting two types of ligand-guided chemistry, we identified novel activity-based probes capable of covalently modifying the active site of matrix metalloproteases (MMPs) without any external trigger. The ability of these probes to label recombinant MMPs was validated in vitro and the identity of the main labelling sites within their S3 ' region unambiguously assigned. We also demonstrated that our affinity probes can react with rhMMP12 at nanogram scale (that is, at 0.07 % (w/w)) in complex proteomes. Finally, this ligand-directed chemistry was successfully applied to label active MMP-12 secreted by eukaryote cells. We believe that this approach could be transferred more widely to many other metalloproteases, thus contributing to tackle their unresolved proteomic profiling in vivo.

Abstract
Botulinum neurotoxin A (BoNT/A) is categorized as a Tier 1 bioterrorism agent and persists within muscle neurons for months, causing paralysis. A readily available treatment that abrogates BoNT/A's toxicity and longevity is a necessity in the event of a widespread BoNT/A attack and for clinical treatment of botulism, yet remains an unmet need. Herein, we describe a comprehensive warhead screening campaign of bifunctional hydroxamate-based inhibitors for the irreversible inhibition of the BoNT/A light chain (LC). Using the 2,4-dichlorocinnamic hydroxamic acid (DCHA) metal-binding pharmacophore modified with a pendent warhead, a total of 37 compounds, possessing 13 distinct warhead types, were synthesized and evaluated for time-dependent inhibition against the BoNT/A LC. Iodoacetamides, maleimides, and an epoxide were found to exhibit time-dependent inhibition and their k GSH measured as a description of reactivity. The epoxide exhibited superior time-dependent inhibition over the iodoacetamides, despite reacting with glutathione (GSH) 51-fold slower. The proximity-driven covalent bond achieved with the epoxide inhibitor was contingent upon the vital hydroxamate-Zn2+ anchor in placing the warhead in an optimal position for reaction with Cys165. Monofunctional control compounds exemplified the necessity of the bifunctional approach, and Cys165 modification was confirmed through high-resolution mass spectrometry (HRMS) and ablation of time-dependent inhibitory activity against a C165A variant. Compounds were also evaluated against BoNT/A-intoxicated motor neuron cells, and their cell toxicity, serum stability, and selectivity against matrix metalloproteinases (MMPs) were characterized. The bifunctional approach allows the use of less intrinsically reactive electrophiles to intercept Cys165, thus expanding the toolbox of potential warheads for selective irreversible BoNT/A LC inhibition. We envision that this dual-targeted strategy is amenable to other metalloproteases that also possess non-catalytic cysteines proximal to the active-site metal center.

Abstract
Carboxypeptidase A (CPA) (EC 3.4.17.1) is one of the main members of the M14 family that release one amino acid from the C-terminal region of the polypeptides at each time. The purpose of the present study was to study the effect of spermidine (NH2(CH2)3NH(CH2)4NH2) on the conformation, thermal stability, and activity of native CPA from bovine pancreas, by employing ultraviolet-visible (UV-Vis) spectroscopy, intrinsic fluorescence, thermal stability, circular dichroism (CD), kinetic techniques and molecular docking. It was found that the decrease in the CPA, UV-Vis absorption could be due to the formation of the CPA-spermidine complexes. The results of fluorescence spectroscopic measurements at the temperatures of 308 and 318 K also revealed that spermidine had the capability to quench the intrinsic fluorescence of CPA with the static mode. Further, the thermodynamic parameters, (Gibbs free-energy, enthalpy and entropy changes) showed that the binding process of spermidine to CPA was spontaneous and the main force in stabilizing the complex was the van der Waals and hydrogen interactions, along with the molecular docking results. In addition, CD spectra and fluorescence results revealed that spermidine had a partial effect on the CPA structure, leading to some changes in its secondary structure. The Tm studies of the CPA-spermidine complex also indicated that the Tm values were enhanced with increasing the spermidine concentration. Kinetic studies further showed that by spermidine binding, the Vmax value and activity of the enzyme were increased.

Abstract
Translationally controlled tumor protein (TCTP), also called histamine releasing factor, is an evolutionarily conserved multifunctional protein in eukaryotes. We previously reported that extracellular TCTP acquires its cytokine-like function following dimerization. This study aims to identify the functional domain involved in the cytokine-like function of dimerized TCTP (dTCTP). We performed X-ray crystallographic studies and a deletion mutant of dTCTP which lacks the flexible loop domain. Synthetic peptides corresponding to TCTP domains and antibodies developed against them were examined for the anti-allergic effect. In an OVA-induced airway inflammation mouse model, inhibitory effect of synthetic peptides was evaluated. dTCTP was mediated by dimers between Cys172s of TCTP monomers. Synthetic peptides corresponding to the flexible loop and helix 2 domain of TCTP, and antibodies against them inhibited dTCTP-induced IL-8 release. In particular, the TCTP mutant lacking the flexible loop domain decreased the inflammatory cytokine activity of dTCTP. We conclude that the flexible loop and helix 2 domain of TCTP are the functional domains of dTCTP. They may have the potential to be therapeutic targets in the suppression of allergic reactions induced by dTCTP.
