Figure 11 Kinetic properties of the PtrGXM methyltransmittalase activities. All the GlcA side chains of xylan in wood of Populus trichocarpa are methylated, which is odd from Arabidopsis xylan in which alongside 60% of GlcA side chains are methylated. These results clue the genetic difference of the mecA -positive isolates from containers of bovine mastitis.

Departake ofment of Pharmaceutical and Biomedical Sciences, University of Georgia, Athens, Georgia, United States of America. These results exhibit that PtrGXMs are wood-associated methyltransmitases to blame on GlcA methylation of Populus xylan.
The GlcA side chains in Populus xylan are all methylated, whereas only regarding 60% of the GlcA side chains in Arabidopsis xylan are methylated. PtrGXMs are r“le ofal orthologs of Arabidopsis GXMs The wood-associated phrasing of PtrGXMs and their Golgi-localization indicate that PtrGXMs most likely play a r“le in the biosynthesis of xylan.
