Functional distinctness in the exoproteomes of marine Synechococcus.

ABSTRACT: The exported protein fraction of an organism may reflect its life strategy and, ultimately, the way it is perceived by the outside world. Bioinformatic prediction of the exported pan-proteome of Prochlorococcus and Synechococcus lineages demonstrated that (i) this fraction of the encoded proteome had a much higher incidence of lineage-specific proteins than the cytosolic fraction (57% and 73% homologue incidence respectively) and (ii) exported proteins are largely uncharacterized to date (54%) compared with proteins from the cytosolic fraction (35%). This suggests that the genomic and functional diversity of these organisms lies largely in the diverse pool of novel functions these organisms export to/through their membranes playing a key role in community diversification, e.g. for niche pa
