    "abstract": "The unicellular cyanobacterium Synechococcus PCC 7942 has been used as a\nmodel organism for studies of prokaryotic circadian rhythms,\ncarbon-concentrating mechanisms, response to a variety of nutrient and\nenvironmental stresses, and cell division. This paper presents the results of\nthe first proteomic exploratory study of Synechococcus PCC 7942. The proteome\nwas analyzed using two-dimensional gel electrophoresis followed by MALDI-TOF\nmass spectroscopy, and database searching. Of 140 analyzed protein spots, 110\nwere successfully identified as 62 different proteins, many of which occurred\nas multiple spots on the gel. The identified proteins were organized into 18\ndifferent functional categories reflecting the major metabolic and cellular\nprocesses occurring in the cyanobacterial cells in the exponential growth\nphase. Among the identified proteins, 14 previously unknown or considered to be\nhypothetical are here shown to be true gene products in Synechococcus sp. PCC\n7942, and may be helpful for annotation of the newly sequenced genome.",
