FunFam 5: Adenylate isopentenyltransferase 4

There are 1 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
Adenylate dimethylallyltransferase (ADP/ATP-dependent). [EC: 2.5.1.112]
(1) Dimethylallyl diphosphate + ADP = diphosphate + N6-(dimethylallyl)adenosine diphosphate. (2) Dimethylallyl diphosphate + ATP = diphosphate + N6-(dimethylallyl)adenosine triphosphate.
  • Involved in the biosynthesis of cytokinins in plants.
  • The IPT4 isoform from the plant Arabidopsis thaliana is specific for ADP and ATP.
  • Other isoforms, such as IPT1 from Arabidopsis thaliana and the enzyme from the common hop, Humulus lupulus, also have a lower activity with AMP (cf. EC 2.5.1.27).
  • Formerly EC 2.5.1.n4.
