Proteins Identified by LC-MS/MS proteomic analysis^a.

aMS-identified proteins with coverage above 25% are reported according to the Hfx. volcanii gene locus tag from the National Center for Biotechnology Information and were unique to samples prepared from strain ΔncsA expressing the FLAG-tagged SAMP1 in tandem with StrepII-tagged NcsA, FLAG-tagged SAMP2 in tandem with StrepII-tagged NcsA, or StrepII-tagged NcsA alone compared to the vector alone. Theoretical molecular mass (Mr) estimated from deduced polypeptide based on Hfx. volcanii DS2 genome sequence.
