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.

textCytosolic homogentisate 1,2-dioxygenase (HGD) catalyzes the reaction of homogentisate and molecular oxygen to form 4-maleylacetoacetate. HGD is a homohexamer, with each monomer binding one Fe(2+) ion as a catalytic cofactor (Titus et al., 2000; Veldhuizen et al., 2005). HGD activity is defective in alkaptonuria patients who excrete excess homogentisate and its oxidized form alkapton in the urine, with further metabolic complications (MIM:203500; Fernandez-Canon et al. 1996; reviewed in Zatkova et al., 2020).
