Abstract
Activity-based protein profiling (ABPP) serves as a chemical proteomic platform to discover and characterize functional amino acids in proteins on the basis of their enhanced reactivity towards small-molecule probes. This approach, to date, has mainly targeted nucleophilic functional groups, such as the side chains of serine and cysteine, using electrophilic probes. We show here that "reverse-polarity" (RP)-ABPP using clickable, nucleophilic hydrazine probes can capture and identify protein-bound electrophiles in cells, including the pyruvoyl cofactor of S-adenosyl-l-methionine decarboxylase (AMD1), which we find is dynamically controlled by intracellular methionine concentrations, and a heretofore unknown modification – an N-terminally bound glyoxylyl group – in the poorly characterized protein secernin-3. RP-ABPP thus provides a versatile method to monitor the metabolic regulation of electrophilic cofactors and discover novel types of electrophilic modifications on proteins in human cells. A chemical proteomic strategy is described for the discovery of protein-bound electrophilic groups in human cells and used to characterize dynamic regulation of the pyruvoyl catalytic cofactor in S-adenosyl-l-methionine decarboxylase and to discover an N-terminal glyoxylyl modification on Secernin proteins.

High dietary taurine inhibits myocardial apoptosis during an atherogenic diet: association with increased myocardial HSP70 and HSF-1 but not caspase 3. Eur J Nutr 2013; 53:929-37.

Abstract
BACKGROUND AND AIM Apoptosis is a major cause of myocyte death, and taurine is anti-apoptotic. Heat shock protein 70 (HSP70) (which is regulated by heat shock factor-HSF-1) is also anti-apoptotic, and caspase 3 stimulates the apoptotic pathway. This study investigated whether taurine affects atherogenic diet-induced myocardial apoptosis, and whether HSP70, HSF-1 and caspase 3 are involved. METHODS New Zealand white rabbits were divided into 3 groups for 4 weeks according to their diet. Group 1 (control) was fed a normal rabbit diet; Group 2 (MC) received a normal rabbit diet with 1% methionine plus 0.5% cholesterol. Group 3 received MC diet + 2.5% taurine (MCT). RESULTS The atherogenic diet did not affect myocardial HSP70 or HSF-1 protein, but increased myocardial apoptotic nuclei to 40% (p < 0.01) versus 7% in con and 12% in MCT (p < 0.01). However, in MCT, myocardial HSP70 expression increased by 42.7% versus con and MC (p = 0.016), HSF-1 by 12% versus con and MC (p < 0.05), and total nuclei count increased by 37% versus MC (p < 0.05). Caspase 3 subunits remained unchanged in all groups, and HSP70 was increased approximately twofold in endothelial layer of arterioles (p = 0.01). CONCLUSION This study shows that taurine could reduce myocardial apoptotic nuclei and thus confer myocardial cytoprotection via stimulating myocardial HSP70 via HSF-1 and caspase 3-independent mechanisms.

Abstract
Nicotinamide N-methyltransferase (NNMT) is overexpressed in a variety of human cancers, where it contributes to tumorigenesis by a still poorly understood mechanism. Here, we show using metabolomics that NNMT impairs the methylation potential of cancer cells by consuming methyl units from S-adenosyl methionine to create the stable metabolic product 1-methylnicotinamide. As a result, NNMT-expressing cancer cells possess an altered epigenetic state that includes hypomethylated histones and other cancer-related proteins combined with heightened expression of pro-tumorigenic gene products. Our findings thus point to a direct mechanistic link between the deregulation of a metabolic enzyme and widespread changes in the methylation landscape of cancer cells.

Methionine/galactose ratio on newborn blood spots useful for reduction of false positives for homocystinuria and galactosemia by high-performance anion-exchange chromatography with pulsed amperometric detection. Clin Chim Acta 2012; 413:182-6. [PMID: 21951896 DOI: 10.1016/j.cca.2011.09.020] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2011] [Revised: 09/12/2011] [Accepted: 09/13/2011] [Indexed: 11/25/2022]
Abstract
BACKGROUND Methionine (Met) in blood and urine is a useful diagnostic marker for homocystinuria (HCU). However, galactosemia could be misdiagnosed as HCU when Met is used as the sole marker, since elevated excretion of Met presents in both galactosemia and HCU. Use of a more specific diagnostic marker in addition to Met is therefore necessary for reduction of false positive results for HCU as well as confirmative diagnosis of HCU. METHODS Chromatographic separation was performed using an anion-exchange column. The levels of Met and galactose (Gal) on blood were measured and Met/Gal ratios were calculated from blood spot samples from 300 normal volunteers, eight galactosemia patients, and three HCU patients. RESULTS The Met/Gal ratio ranged 0-4.95 for normal blood spots (n=300), 0-0.22 for galactosemia samples (n=8), and >1250 for HCU patient samples. CONCLUSIONS Separation, extraction, and deproteinization procedures were established for Met and Gal in blood spots. And Met/Gal ratio allowed HCU to clearly distinguish from galactosemia. As a way of second tier confirmative analysis, the ratio is the best way to reduce false positives. The assay is most appropriate to reduce false positives in labs that do not screen for galactosemia.

Abstract
Electrophilic halogenating agents, including hypohalous acids and haloamines, oxidize free methionine and the N-terminal methionines of peptides and proteins (e.g., Met-1 of anti-inflammatory peptide 1 and ubiquitin) to produce dehydromethionine (a five-membered isothiazolidinium heterocycle). Amide derivatives of methionine are oxidized to the corresponding sulfoxide derivatives under the same reaction conditions (e.g., Met-3 of anti-inflammatory peptide 1). Other biological oxidants, including hydrogen peroxide and peroxynitrite, also produce only the corresponding sulfoxides. Hypothiocyanite does not react with methionine residues. We suggest that dehydromethionine may be a useful biomarker for the myeloperoxidase-induced oxidative stress associated with many inflammatory diseases.
