UniProt functional annotation for O57728 | ||
|
|
|
|
|
|
||
| UniProt code: O57728. |
|
||
| Organism: | |
Pyrococcus horikoshii (strain ATCC 700860 / DSM 12428 / JCM 9974 / NBRC 100139 / OT-3). |
| Taxonomy: | |
Archaea; Euryarchaeota; Thermococci; Thermococcales; Thermococcaceae; Pyrococcus. |
|
||
|
||
| Function: | |
Produces ATP from ADP in the presence of a proton gradient across the membrane. The archaeal alpha chain is a catalytic subunit. |
|
||
| Catalytic activity: | |
Reaction=ATP + 4 H(+)(in) + H2O = ADP + 5 H(+)(out) + phosphate; Xref=Rhea:RHEA:57720, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616, ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; EC=7.1.2.2; |
| Ptm: | |
This protein undergoes a protein self splicing that involves a post-translational excision of the VDE intervening region (intein) followed by peptide ligation. {ECO:0000305}. |
| Miscellaneous: | |
The intein interrupts the ATP-binding site. |
| Similarity: | |
Belongs to the ATPase alpha/beta chains family. {ECO:0000305}. |
