Identified proteins.

<p>The spot number refers to the numbers in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0083817#pone-0083817-g002" target="_blank">Fig. 2</a>. The MOWSE (MOlecular Weight SEarch) score is used to identify proteins from the molecular weight of peptides produced by proteolytic digestion. Mr, theoretical molecular mass; p<i>I</i>, isoelectric point. The sequence coverage of matching peptides was calculated by using Biotools™ software.
