Identification and functional characterization of S-nitrosated proteins from Klebsormidium nitens in response to salt stress

2023

The small gaseous molecule nitric oxide (NO) is well established as a major ubiquitouscomponent of cell signalling. A key signalling mechanism mediating NO effects is Snitrosation, a post-translational modification by which NO can impact the target proteinactivities, subcellular localizations, and capacities to form protein complexes. The identificationof proteins targeted by NO is of major interest in order to elucidate NO functions. Interestingly,land plants lack NO synthase (NOS), which is the main enzyme for NO synthesis in metazoans,while a few algal species possess it, thus raising many interrogations. Therefore, we focused onthe identification of S-nitrosated proteins during salt str…
