Proteins identified by LC-ESI-MS/MS associated with biogenic and nonbiogenic elemental selenium^a

^aFor matches relating to homologous proteins in different organisms, all accession numbers (GI numbers) are given, yet only the organism with the highest ion score is mentioned. Proteins with an anticipated role in selenium reduction are highlighted in gray.

^bA protein score greater than 42 is considered significant (P < 0.05).

^c% Apparent mass, percentage of the apparent mass as determined by SDS.
