The plant cell wall mostly comprises complex glycans, which are synthesized by numerous enzymes located in the Golgi apparatus and plasma membrane. Protein-protein interactions have been shown to constitute an important organizing principle for glycan biosynthetic enzymes in mammals and yeast. Recent genetic and biochemical data also indicate that such interactions could be common in plant cell wall biosynthesis. In this review, we examine the new findings in protein-protein interactions among plant cell wall biosynthetic enzymes and discuss the possibilities for enzyme complexes in the Golgi apparatus. These new insights in the field may contribute to novel strategies for molecular engineering of the cell wall.
