retinal metabolic process retinal isomerization https://github.com/geneontology/go-ontology/issues/23669 This process term replaces 'retinal isomerase' because the Enzyme Commission has determined that the reaction is known to be catalyzed by a pathway involving multiple steps, catalyzed by EC:1.1.1.300, EC:2.3.1.135, EC:3.1.1.64, and EC:1.1.1.315. hjd The reactions involved in isomerization of all trans to all cis retnal. biological_process GO:0106434 2022-09-28T16:44:26Z
