UniProt functional annotation for Q2G036 | ||
|
|
|
|
|
|
||
| UniProt code: Q2G036. |
|
||
| Organism: | |
Staphylococcus aureus (strain NCTC 8325 / PS 47). |
| Taxonomy: | |
Bacteria; Firmicutes; Bacilli; Bacillales; Staphylococcaceae; Staphylococcus. |
|
||
|
||
| Function: | |
Cleaves peptides in various proteins in a process that requires ATP hydrolysis. Has a chymotrypsin-like activity. Plays a major role in the degradation of misfolded proteins. {ECO:0000255|HAMAP-Rule:MF_00444}. |
|
||
| Catalytic activity: | |
Reaction=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).; EC=3.4.21.92; Evidence={ECO:0000255|HAMAP-Rule:MF_00444}; |
| Subunit: | |
Fourteen ClpP subunits assemble into 2 heptameric rings which stack back to back to give a disk-like structure with a central cavity, resembling the structure of eukaryotic proteasomes. {ECO:0000255|HAMAP- Rule:MF_00444}. |
| Subcellular location: | |
Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00444}. |
| Similarity: | |
Belongs to the peptidase S14 family. {ECO:0000255|HAMAP- Rule:MF_00444}. |
