Definition of ech

• Curated proteins or TIGRFams with EC 4.2.1.150
• Ignore hits to Q97MS7 when looking for 'other' hits (short-chain-enoyl-CoA hydratase (EC 4.2.1.150))
• Curated sequence BPHYT_RS17335: trans-2,3-dehydroadipyl-CoA hydratase (EC 4.2.1.17)
• Curated sequence GFF2389: Enoyl-CoA hydratase [valine degradation] (EC 4.2.1.17)
• Ignore hits to items matching 4.2.1.17 when looking for 'other' hits
• Comment: Psest_2437 (GFF2389) is the enoyl-CoA hydrotase for both isoleucine and valine degradation, which implies that (S)-3-hydroxybutanoyl-CoA is a substrate. Q97MS7 is misannotated in BRENDA. BPHYT_RS17335 was misannotated as paaF; it is very similar to the ech H16_A3307, which is a different explanation for its role in phenylacetate utilization. Short-chain enoyl-CoA hydratases are sometimes given EC 4.2.1.17 instead, so those are ignored.
