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.

textLeukotriene A4 hydrolase (LTA4H) is a monomeric, soluble enzyme that uses a Zn2+ cofactor to catalyse the hydrolysis of the allylic epoxide leukotriene A4 (LTA4) (McGee & Fitzpatrick 1985). LTA4H may also be able to catalyse the hydrolysis of 17R(6)-epoxy-docosahexaenoic acid (17R(16)-epoxy-DHA) to 10(R),17(R)-dihydroxydocosa-4Z,7Z,11E,13E,15Z,19Z-hexaenoic acid (aspirin-triggered (neuro)protectin D1, AT-(N)PD1) (Serhan et al. 2011). In human cells, AT-(N)PD1 decreased PMN migration as well as enhancing efferocytosis of apoptotic human PMN by macrophages, indicating AT-(N)PD1 as a potent anti-inflammatory proresolving molecule (Serhan et al. 2011).
