FunFam 17189: Leukotoxin translocation ATP-binding protein LktB

There are 3 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
Peptide-transporting ATPase. [EC: 3.6.3.43]
ATP + H(2)O + peptide(In) = ADP + phosphate + peptide(Out).
  • A family of enzymes that exports alpha-hemolysin, cyclolysin, colicin V and siderophores from Gram-negative bacteria, and bacteriocin, subtilin, competence factor and pediocin from Gram-positive bacteria.

Adenosinetriphosphatase. [EC: 3.6.1.3]
ATP + H(2)O = ADP + phosphate.
  • Many enzymes previously listed under this number are now listed separately as EC 3.6.1.32 to EC 3.6.1.39.
  • The remaining enzymes, not separately listed on the basis of some function coupled with hydrolyzes of ATP, include enzymes dependent on Ca(2+), Mg(2+), anions, H(+) or DNA.
  • Formerly EC 3.6.1.4.

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.
