FunFam 630559: Fis family transcriptional regulator

There are 6 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
Nucleoside-triphosphate phosphatase. [EC: 3.6.1.15]
NTP + H(2)O = NDP + phosphate.
  • The enzyme is found in eukaryotes and thermophilic bacteria, but appears to be absent from mesophilic bacteria.
  • Also hydrolyzes nucleoside diphosphates, thiamine diphosphate and FAD.
  • The enzyme from the plant Pisum sativum (garden pea) is regulated by calmodulin.

(S)-limonene 6-monooxygenase. [EC: 1.14.13.48]
(-)-(S)-limonene + NADPH + O(2) = (-)-trans-carveol + NADP(+) + H(2)O.
  • High specificity, but NADH can act instead of NADPH, although more slowly.

(S)-limonene 7-monooxygenase. [EC: 1.14.13.49]
(-)-(S)-limonene + NADPH + O(2) = (-)-perillyl alcohol + NADP(+) + H(2)O.
  • High specificity, but NADH can act instead of NADPH, although more slowly.

Carveol dehydrogenase. [EC: 1.1.1.243]
(-)-trans-carveol + NADP(+) = (-)-carvone + NADPH.
    		 2 A0A0F0CK81 A0A1C5ZPY8
    Perillyl-alcohol dehydrogenase. [EC: 1.1.1.144]
    Perillyl alcohol + NAD(+) = perillyl aldehyde + NADH.
    • Oxidizes a number of primary alcohols with the alcohol group allylic to an endocyclic double bond and a 6-membered ring, either aromatic or hydroaromatic.
    		 2 A0A0F0CK81 A0A1C5ZPY8
    Acetone carboxylase. [EC: 6.4.1.6]
    Acetone + CO(2) + ATP + 2 H(2)O = acetoacetate + AMP + 2 phosphate.
    • The enzyme from Xanthobacter sp. strain Py2 also carboxylates butan- 2-one to 3-oxopentanoate.
