Abstract
Nitric oxide (NO) has emerged as an important signal molecule in plants, having myriad roles in plant development. In addition, NO also orchestrates both biotic and abiotic stress responses, during which intensive cellular metabolic reprogramming occurs. Integral to these responses is the location of NO biosynthetic and scavenging pathways in diverse cellular compartments, enabling plants to effectively organize signal transduction pathways. NO regulates plant metabolism and, in turn, metabolic pathways reciprocally regulate NO accumulation and function. Thus, these diverse cellular processes are inextricably linked. This review addresses the numerous redox pathways, located in the various subcellular compartments that produce NO, in addition to the mechanisms underpinning NO scavenging. We focus on how this molecular dance is integrated into the metabolic state of the cell. Within this context, a reciprocal relationship between NO accumulation and metabolite production is often apparent. We also showcase cellular pathways, including those associated with nitrate reduction, that provide evidence for this integration of NO function and metabolism. Finally, we discuss the potential importance of the biochemical reactions governing NO levels in determining plant responses to a changing environment.

Endogenous S-nitrosocysteine proteomic inventories identify a core of proteins in heart metabolic pathways. Redox Biol 2021; 47:102153. [PMID: 34610554 PMCID: PMC8497991 DOI: 10.1016/j.redox.2021.102153] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2021] [Revised: 09/24/2021] [Accepted: 09/27/2021] [Indexed: 12/25/2022] Open
Abstract
Protein cysteine residues are essential for protein folding, participate in enzymatic catalysis, and coordinate the binding of metal ions to proteins. Enzymatically catalyzed and redox-dependent post-translational modifications of cysteine residues are also critical for signal transduction and regulation of protein function and localization. S-nitrosylation, the addition of a nitric oxide equivalent to a cysteine residue, is a redox-dependent modification. In this study, we curated and analyzed four different studies that employed various chemoselective platforms coupled to mass spectrometry to precisely identify S-nitrosocysteine residues in mouse heart proteins. Collectively 1974 S-nitrosocysteine residues in 761 proteins were identified and 33.4% were identified in two or more studies. A core of 75 S-nitrosocysteine residues in 44 proteins were identified in all four studies. Bioinformatic analysis of each study indicated a significant enrichment of mitochondrial proteins participating in metabolism. Regulatory proteins in glycolysis, TCA cycle, oxidative phosphorylation and ATP production, long chain fatty acid β-oxidation, and ketone and amino acid metabolism constitute the major functional pathways impacted by protein S-nitrosylation. In the cardiovascular system, nitric oxide signaling regulates vasodilation and cardiac muscle contractility. The meta-analysis of the proteomic data supports the hypothesis that nitric oxide signaling via protein S-nitrosylation is also a regulator of cardiomyocyte metabolism that coordinates fuel utilization to maximize ATP production. As such, protein cysteine S-nitrosylation represents a third functional dimension of nitric oxide signaling in the cardiovascular system to ensure optimal cardiac function.

Abstract
Post-translational modification by S-nitrosylation regulates numerous cellular functions and impacts most proteins across phylogeny. We describe a protocol for isolating S-nitrosylated proteins (SNO-proteins) from C. elegans, suitable for assessing SNO levels of individual proteins and of the global proteome. This protocol features efficient nematode lysis and SNO capture, while protection of SNO proteins from degradation is the major challenge. This protocol can be adapted to mammalian tissues. For complete information on the generation and use of this protocol, please refer to Seth et al. (2019).

Abstract
Cysteine oxidative modification of cellular proteins is crucial for many aspects of cardiac hypertrophy development. However, integrated dissection of multiple types of cysteine oxidative post-translational modifications (O-PTM) of proteomes in cardiac hypertrophy is currently missing. Here we developed a novel discovery platform that encompasses a customized biotin switch-based quantitative proteomics pipeline and an advanced analytic workflow to comprehensively profile the landscape of cysteine O-PTM in an ISO-induced cardiac hypertrophy mouse model. Specifically, we identified a total of 1655 proteins containing 3324 oxidized cysteine sites by at least one of the following three modifications: reversible cysteine O-PTM, cysteine sulfinylation (CysSO2H), and cysteine sulfonylation (CysSO3H). Analyzing the hypertrophy signatures that are reproducibly discovered from this computational workflow unveiled four biological processes with increased cysteine O-PTM. Among them, protein phosphorylation, creatine metabolism, and response to elevated Ca2+ pathways exhibited an elevation of cysteine O-PTM in early stages, whereas glucose metabolism enzymes were increasingly modified in later stages, illustrating a temporal regulatory map in cardiac hypertrophy. Our cysteine O-PTM platform depicts a dynamic and integrated landscape of the cysteine oxidative proteome, through the extracted molecular signatures, and provides critical mechanistic insights in cardiac hypertrophy. Data are available via ProteomeXchange with identifier PXD010336.

Abstract
Reactive nitrogen species (RNS) and their cognate redox signalling networks pervade almost all facets of plant growth, development, immunity, and environmental interactions. The emerging evidence implies that specificity in redox signalling is achieved by a multilayered molecular framework. This encompasses the production of redox cues in the locale of the given protein target and protein tertiary structures that convey the appropriate local chemical environment to support redox-based, post-translational modifications (PTMs). Nascent nitrosylases have also recently emerged that mediate the formation of redox-based PTMs. Reversal of these redox-based PTMs, rather than their formation, is also a major contributor of signalling specificity. In this context, the activities of S-nitrosoglutathione (GSNO) reductase and thioredoxin h5 (Trxh5) are a key feature. Redox signalling specificity is also conveyed by the unique chemistries of individual RNS which is overlaid on the structural constraints imposed by tertiary protein structure in gating access to given redox switches. Finally, the interactions between RNS and ROS (reactive oxygen species) can also indirectly establish signalling specificity through shaping the formation of appropriate redox cues. It is anticipated that some of these insights might function as primers to initiate their future translation into agricultural, horticultural, and industrial biological applications.

Abstract
Nitric oxide (NO), initially identified as endothelium-derived relaxing factor (EDRF), is a gaso-transmitter with important regulatory roles in the cardiovascular, nervous and immune systems. In the former, this diatomic molecule and free radical gas controls vascular tone and cardiac mechanics, among others. In the cardiovascular system, it is now understood that β-adrenergic receptor (βAR) activation is a key modulator of NO generation. Therefore, it is not surprising that the up-regulation of G protein-coupled receptor kinases (GRKs), in particular GRK2, that restrains βAR activity contributes to impaired cardiovascular functions via alteration of NO bioavailability. This review, will explore the specific interrelation between βARs, GRK2 and NO in the cardiovascular system and their inter-relationship for the pathogenesis of the onset of disease. Last, we will update the readers on the current status of GRK2 inhibitors as a potential therapeutic strategy for heart failure with an emphasis on their ability of rescuing NO bioavailability.
