Relative Abundance of Proteins Across Four Fractions of Golgi Membranes After FFE.

(A) Portion of the profile of fractions from FFE enriched in Golgi proteins.

(B) Profiles of proteins proposed as markers for ER- and Golgi-residence (in blue and red, respectively). Distribution of abundance of three proteins, ECA4, SYP32, and α-Man (in green), did not strictly follow an expected ER- or Golgi-residence profile. SNAP, Synaptosomal nerve-associated protein.

(C) Enzymes of nucleotide-sugar interconversion.

(D) Proteins of pectin and hemicellulose synthesis.

(E) CesAs.

(F) Profiles of three proteins associated with cellulose synthesis, STELLO, KOR, and COBRA (in blue), with CslF proteins (in red).

A complete list of the proteins associated with noncellulosic polysaccharide synthesis and metabolism is provided in Supplemental Data Set 3.
