UniProt functional annotation for P28366 | ||
|
|
|
|
|
|
||
| UniProt code: P28366. |
|
||
| Organism: | |
Bacillus subtilis (strain 168). |
| Taxonomy: | |
Bacteria; Firmicutes; Bacilli; Bacillales; Bacillaceae; Bacillus. |
|
||
|
||
| Function: | |
Part of the Sec protein translocase complex. Interacts with the SecYEG preprotein conducting channel. Has a central role in coupling the hydrolysis of ATP to the transfer of proteins into and across the cell membrane, serving as an ATP-driven molecular motor driving the stepwise translocation of polypeptide chains across the membrane. {ECO:0000255|HAMAP-Rule:MF_01382}. |
|
||
| Catalytic activity: | |
Reaction=ATP + H(2)O + cellular protein(Side 1) = ADP + phosphate + cellular protein(Side 2).; EC=7.4.2.8; Evidence={ECO:0000255|HAMAP- Rule:MF_01382, ECO:0000305|PubMed:8440733}; |
| Cofactor: | |
Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000255|HAMAP-Rule:MF_01382}; Note=May bind 1 zinc ion per subunit. {ECO:0000255|HAMAP- Rule:MF_01382}; |
| Subunit: | |
Part of the essential Sec protein translocation apparatus which comprises SecA, SecYEG and auxiliary proteins SecDF. Other proteins may be involved. Monomer and many different homodimers can be isolated (PubMed:16989859), some of which are not formed in the presence of a synthetic signal peptide. A single SecA monomer interacts with SecY in the channel. {ECO:0000269|PubMed:16989859, ECO:0000269|PubMed:18923516}. |
| Subcellular location: | |
Cell membrane {ECO:0000255|HAMAP-Rule:MF_01382}; Peripheral membrane protein {ECO:0000255|HAMAP-Rule:MF_01382}; Cytoplasmic side {ECO:0000255|HAMAP-Rule:MF_01382}. Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01382}. Note=Distribution is 50-50. {ECO:0000255|HAMAP-Rule:MF_01382}. |
| Similarity: | |
Belongs to the SecA family. {ECO:0000255|HAMAP- Rule:MF_01382}. |
