Highlights

  • Nitric oxide (NO) is an important redox molecule fulfilling a wide variety of signalling functions

  • One of its most important modes of action is protein S-nitrosation, the covalent attachment of NO to the thiol group of protein cysteine residues.Tyrosine nitration refers to the addition of a nitro group to susceptible tyrosine residues in the ortho position to the hydroxyl group yielding 3-nitrotyrosine

  • Investigation of NO production and NO signalling is challenging because many available methods suffer from a lack of specificity and/or sensitivity, or are just unsuitable for the detection of NO in vivo.in some cases, the production might be restricted to a few cells, such as guard cells or pollen (Corpas et al, 2004; Prado et al, 2004; Neil et al, 2008)

Summary

Nitric oxide sensor proteins with revolutionary potential

Nitric oxide (NO) is involved in regulation of plant growth and development, as well as the response to biotic and abiotic stressors. Nitric oxide (NO) is an important redox molecule fulfilling a wide variety of signalling functions. These cover growth and development, as well as stress responses, in humans, animals, plants, fungi and bacteria (Besson-Bard et al, 2008; Sudhamsu and Crane, 2009; Murad, 2011; Arasimowicz-Jelonek and Floryszak-Wieczorek, 2016; Byung-Wook et al, 2016; Canovas et al, 2016). NO can be produced by oxidative and reductive pathways (Moreau et al, 2010;Yu et al, 2014) and is sensed within the cell through redox modification of proteins, such as cysteine nitrosation, tyrosine nitration and metal nitrosylation (Astier et al, 2012; Astier and Lindermayr, 2012; Mata-Perez et al, 2016). In a direct metal nitrosylation reaction, NO (Lewis base) binds to the transition metal (Lewis acid) of metalloproteins yielding a metal–nitrosyl complex
