FunFam 114852: Probable carboxylesterase 1

There are 4 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Carboxylesterase. [EC: 3.1.1.1]
A carboxylic ester + H(2)O = an alcohol + a carboxylate.
  • Wide specificity; also hydrolyzes vitamin A esters.
  • The enzymes from microsomes also catalyze the reactions of EC 3.1.1.2, EC 3.1.1.5, EC 3.1.1.6, EC 3.1.1.23, EC 3.1.1.28, EC 3.1.2.2, EC 3.5.1.4, and EC 3.5.1.13.
  • Formerly EC 3.1.1.12.

2-hydroxyisoflavanone dehydratase. [EC: 4.2.1.105]
(1) 2,4',7-trihydroxyisoflavanone = daidzein + H(2)O. (2) 2,4',5,7-tetrahydroxyisoflavanone = genistein + H(2)O.
  • Catalyzes the final step in the formation of the isoflavonoid skeleton.
  • The reaction also occurs spontaneously.
 3 A0A0R0LP27 Q5NUF3 Q5NUF4
Tuliposide A-converting enzyme. [EC: 4.2.99.22]
6-tuliposide A = tulipalin A + D-glucose.
  • Isolated from the plant Tulipa gesneriana (tulip).
  • The reaction is an intramolecular transesterification producing the lactone.
  • The enzyme also has a weak activity with 6-tuliposide B and 6-O- benzoyl-D-glucose.
 2 I4DST8 I4DST9
Triacylglycerol lipase. [EC: 3.1.1.3]
Triacylglycerol + H(2)O = diacylglycerol + a carboxylate.
  • The pancreatic enzyme acts only on an ester-water interface; the outer ester links are preferentially hydrolyzed.
