Global analysis of the proteins identified by LC-MS/MS in the yECM and LGM of wt and gup1∆ mutant strains. a Numbers of proteins unequivocally identified by GC-MS/MS in yECM and liquid growth medium LGM, of S. cerevisiae wt and gup1∆ mutant: 401 proteins are exclusive of wt yECM, 213 of which are common to gup1∆ mutant, while 159 are exclusive of this mutant yECM. In opposition, and as previously reported [26], the gup1∆ mutant secretes 3.5x more proteins into liquid growth medium than wt strain. b Compared functional distribution of the proteins found by LC-MS/MS in S. cerevisiae wt yECM (upper panel) and in liquid medium LGM (lower panel). Functional classes absent from LGM are mentioned in grey insert. c Identical compared functional distribution from the proteins found in gup1∆ yECM (upper panel) and in LGM (lower panel)
