Proteome Remodeling in Response to Sulfur Limitation in Candidatus Pelagibacter ubique


ABSTRACT: P. ubique was investigated to understand the response to limited sulfur in seawater. Sulfur absorption was found to be localized to a rapidly evolving region of the genome.

The alphaproteobacterium "<i>Candidatus</i> Pelagibacter ubique" strain HTCC1062 and most other members of the SAR11 clade lack genes for assimilatory sulfate reduction, making them dependent on organosulfur compounds that occur naturally in seawater. To investigate how these cells adapt to sulfur limitation, batch cultures were grown in defined medium containing either limiting or nonlimiting amounts of dimethylsulfoniopropionate (DMSP) as the sole sulfur source.
