TBL3 and TBL31, Two Arabidopsis DUF231 Domain Proteins, are Required for 3-O-Monoacetylation of Xylan.

Abstract excerpt

Xylan, a major constituent of secondary cell walls, is made of a linear chain of β-1,4-linked xylosyl residues that are often substituted with glucuronic acid/methylglucuronic acid side chains and acetylated at O-2 and O-3. Previous studies have shown that ESK1, an Arabidopsis DUF231 protein, is an acetyltransferase catalyzing 2-O- and 3-O-monoacetylation of xylan. However, the esk1 mutation only causes a partial...
