FunFam 633147: ATP-dependent Clp protease ClpV

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
Endopeptidase Clp. [EC: 3.4.21.92]
Hydrolysis of proteins to small peptides in the presence of ATP and magnesium. Alpha-casein is the usual test substrate. In the absence of ATP, only oligopeptides shorter than five residues are hydrolyzed (such as succinyl-Leu-Tyr-|-NHMec; and Leu-Tyr-Leu-|-Tyr-Trp, in which cleavage of the -Tyr-|-Leu- and -Tyr-|-Trp bonds also occurs).
  • Belongs to peptidase family S14.

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.

Endopeptidase La. [EC: 3.4.21.53]
Hydrolysis of proteins in presence of ATP.
  • ATP hydrolysis is linked with peptide bond hydrolysis.
  • Vanadate inhibits both reactions.
  • A similar enzyme occurs in animal mitochondria.
  • Belongs to peptidase family S16.

Phospho-N-acetylmuramoyl-pentapeptide-transferase. [EC: 2.7.8.13]
UDP-Mur2Ac(oyl-L-Ala-gamma-D-Glu-L-Lys-D-Ala-D-Ala) + undecaprenyl phosphate = UMP + Mur2Ac(oyl-L-Ala-gamma-D-Glu-L-Lys-D-Ala-D-Ala)- diphosphoundecaprenol.
  • In Gram-negative and some Gram-positive organisms the L-lysine is replaced by meso-2,6-diaminoheptanedioate (meso-2,6-diaminopimelate, A2pm), which is combined with adjacent residues through its L-center.
  • The undecaprenol involved is ditrans,octacis-undecaprenol.
