FunFam 630086: 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
(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.

Histidine kinase. [EC: 2.7.13.3]
ATP + protein L-histidine = ADP + protein N-phospho-L-histidine.
  • This entry has been included to accommodate those protein-histidine kinases for which the phosphorylation site has not been established (i.e. either the pros- or tele-nitrogen of histidine).
  • A number of histones can act as acceptor.
 5 A0A172XKA3 A0A1A5V8U4 A0A1L6CED6 E1UKF5 G4EU16
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.
 4 A0A085H8B1 A0A1B7JJA0 M5R778 M5RE36
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.
 3 A0A0B5WZP4 A0A0J1FBA5 A0A0J1FH36
(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.
 3 A0A0H4NV21 A0A0J1FBA5 A0A0J1FH36
Carveol dehydrogenase. [EC: 1.1.1.243]
(-)-trans-carveol + NADP(+) = (-)-carvone + NADPH.
