Application of proteomics has made a profound impact on the cyanobacterial
research. It has not only provided a global identification of expressed
proteins in cyanobacterial cells, but has also brought valuable
insights into dynamics of cell responses to environmental challenges,
regulation mechanisms, structure of protein complexes,
compartmentalization, and other important biological questions. In this
review, we highlight current trends in proteomics of cyanobacteria and
bring to focus rising techniques which have a huge potential in
expanding our knowledge about cyanobacterial proteins and in developing
cyanobacteria-based biotechnological applications.
