Query author contributions in Reactome

Reactome depends on collaboration between our curation team and outside experts to assemble and peer-review its pathway modules. The integration of ORCID within Reactome enables us to meet a key challenge with authoring, curating and reviewing biological information by incentivizing and crediting the external experts that contribute their expertise and time to the Reactome curation process. More information is available at ORCID and Reactome.

If you have an ORCID ID that is not listed on this page, please forward this information to us and we will update your Reactome pathway records.

textSubstitution of xylan by GlcA is known to require two enzymes in Arabidopsis stems, GUX1 (glucuronic acid substitution of xylan 1 and GUX2). GUX1 is responsible for most of the GlcA substitution, whilst GUX2 contributes a minor proportion of thesesubstitutions. Mutation of either Glux1 or Glux2 or both does not affect Xylan backbone indicating that Glux1 and Glux2 does not provide glycotransferase activity for the synthesis of the ?-(1,4)-linked xylose backbone.
