The activities of GXM1, GXM2 and GXM3 (this protein) are responsible for all of the glucuronic acid (GlcA) methylation in xylan in stems, and the degree of GlcA methylation in xylan can be modified by altered expression of GXMs.
Title: Modification of the degree of 4-O-methylation of secondary wall glucuronoxylan.

DUF579 domain-containing proteins, GXM1, GXM2 and GXM3, are methyltransferases catalyzing 4-O-methylation of glucuronic acid side chains on xylan.
Title: Three Arabidopsis DUF579 domain-containing GXM proteins are methyltransferases catalyzing 4-o-methylation of glucuronic acid on xylan.

An Arabidopsis gene (At1g33800) encodes a cation-dependent glucuronoxylan methyltransferase (GXMT)that specifically methylates O-4 of the GlcA substituents of glucuronoxylan.
Title: 4-O-methylation of glucuronic acid in Arabidopsis glucuronoxylan is catalyzed by a domain of unknown function family 579 protein.
