Table 1.

The 7 potential Chlamydomonas PCAPs identified. 0.3M and 0.5M represent the NaCl elution concentrations. The numbers of the MS/MS identified matching peptides from the elutions are shown under each salt concentration. The annotations are based on predicted homologs in yeast, human and Arabidopsis, with e-values shown for the best Blast matches. The conventions are used in Table 2 and supplementary tables
