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.

commentFUNCTION Converts unsaturated trans-2-enoyl-CoA species ((2E)-enoyl-CoA) to the corresponding (3S)-3hydroxyacyl-CoA species through addition of a water molecule to the double bond (PubMed:25125611, PubMed:26251176). Catalyzes the hydration of medium- and short-chained fatty enoyl-CoA thioesters from 4 carbons long (C4) up to C16 (PubMed:26251176). Has high substrate specificity for crotonyl-CoA ((2E)-butenoyl-CoA) and moderate specificity for acryloyl-CoA, 3-methylcrotonyl-CoA (3-methyl-(2E)-butenoyl-CoA) and methacrylyl-CoA ((2E)-2-methylpropenoyl-CoA) (PubMed:26251176). Can bind tiglyl-CoA (2-methylcrotonoyl-CoA), but hydrates only a small amount of this substrate (PubMed:26251176). Plays a key role in the beta-oxidation spiral of short- and medium-chain fatty acid oxidation (PubMed:25125611, PubMed:26251176). At a lower rate than the hydratase reaction, catalyzes the isomerase reaction of trans-3-enoyl-CoA species (such as (3E)-hexenoyl-CoA) to trans-2-enoyl-CoA species (such as (2E)-hexenoyl-CoA), which are subsequently hydrated to 3(S)-3-hydroxyacyl-CoA species (such as (3S)-hydroxyhexanoyl-CoA) (By similarity).CATALYTIC ACTIVITY a (3S)-3-hydroxyacyl-CoA = a (2E)-enoyl-CoA + H2OCATALYTIC ACTIVITY a (3E)-enoyl-CoA = a 4-saturated (2E)-enoyl-CoACATALYTIC ACTIVITY (3E)-hexenoyl-CoA = (2E)-hexenoyl-CoACATALYTIC ACTIVITY (3S)-3-hydroxybutanoyl-CoA = (2E)-butenoyl-CoA + H2OCATALYTIC ACTIVITY 3-hydroxyisovaleryl-CoA = 3-methylbut-2-enoyl-CoA + H2OCATALYTIC ACTIVITY 3-hydroxypropanoyl-CoA = acryloyl-CoA + H2OCATALYTIC ACTIVITY 3-hydroxybutanoyl-CoA = (2E)-butenoyl-CoA + H2OCATALYTIC ACTIVITY 2-methylpropenoyl-CoA + H2O = (S)-3-hydroxyisobutanoyl-CoACATALYTIC ACTIVITY (3S)-hydroxyhexanoyl-CoA = (2E)-hexenoyl-CoA + H2OCATALYTIC ACTIVITY (3S)-hydroxydecanoyl-CoA = (2E)-decenoyl-CoA + H2OBIOPHYSICOCHEMICAL PROPERTIES Lipid metabolism; fatty acid beta-oxidation.SUBUNIT Homohexamer; dimer of trimers.INTERACTION Liver, fibroblast, muscle. Barely detectable in spleen and kidney.DISEASE The disease is caused by variants affecting the gene represented in this entry.SIMILARITY Belongs to the enoyl-CoA hydratase/isomerase family.
