S-nitrosylation is a nitric oxide (NO)-based post-translational modification
regulating protein function and signalling. We used a combination between the
biotin switch method and labelling with isotope-coded affinity tag to identify
endogenously S-nitrosylated peptides in Arabidopsis thaliana proteins extracted
from plantlets. The relative level of S-nitrosylation in the identified peptides
was compared between unstressed and cold-stress seedlings. We thereby detected
62 endogenously nitrosylated peptides out of which 20 are over-nitrosylated
following cold exposure. Taken together these data provide a new repertoire of
endogenously S-nitrosylated proteins in Arabidopsis with cysteine
S-nitrosylation site. Furthermore they highlight the quantitative modification
of the S-nitrosylation status of specific cysteine following cold stress.
