Part of a complex composed of FtsB, FtsL and FtsQ.
Belongs to the universal ribosomal protein uS7 family.
One of the primary rRNA binding proteins, it binds directly to 16S rRNA where it nucleates assembly of the head domain of the 30S subunit. Is located at the subunit interface close to the decoding center, probably blocks exit of the E-site tRNA.
Part of the 30S ribosomal subunit. Contacts proteins S9 and S11.
Belongs to the universal ribosomal protein uS12 family.
Interacts with and stabilizes bases of the 16S rRNA that are involved in tRNA selection in the A site and with the mRNA backbone. Located at the interface of the 30S and 50S subunits, it traverses the body of the 30S subunit contacting proteins on the other side and probably holding the rRNA structure together. The combined cluster of proteins S8, S12 and S17 appears to hold together the shoulder and platform of the 30S subunit.
Part of the 30S ribosomal subunit. Contacts proteins S8 and S17. May interact with IF1 in the 30S initiation complex.
With S4 and S5 plays an important role in translational accuracy.
Belongs to the thioester dehydratase family. FabZ subfamily.
Involved in unsaturated fatty acids biosynthesis. Catalyzes the dehydration of short chain beta-hydroxyacyl-ACPs and long chain saturated and unsaturated beta-hydroxyacyl-ACPs.
Homodimer. Forms a membrane-associated complex with FtsX.
Part of the ABC transporter FtsEX involved in cellular division. Important for assembly or stability of the septal ring.
Belongs to the universal ribosomal protein uS5 family.
Located at the back of the 30S subunit body where it stabilizes the conformation of the head with respect to the body.
Part of the 30S ribosomal subunit. Contacts proteins S4 and S8.
The N-terminal domain interacts with the head of the 30S subunit; the C-terminal domain interacts with the body and contacts protein S4. The interaction surface between S4 and S5 is involved in control of translational fidelity.
With S4 and S12 plays an important role in translational accuracy.
Binds 1 iron-sulfur cluster per subunit.
Required for insertion of 4Fe-4S clusters for at least IspG.
Belongs to the RNA polymerase subunit omega family.
Promotes RNA polymerase assembly. Latches the N- and C-terminal regions of the beta' subunit thereby facilitating its interaction with the beta and alpha subunits.
The RNAP catalytic core consists of 2 alpha, 1 beta, 1 beta' and 1 omega subunit. When a sigma factor is associated with the core the holoenzyme is formed, which can initiate transcription.
Belongs to the acyl coenzyme A hydrolase family.
Belongs to the urease gamma subunit family.
Heterotrimer of UreA (gamma), UreB (beta) and UreC (alpha) subunits. Three heterotrimers associate to form the active enzyme.
Member of the two-component regulatory system NtrB/NtrC, which controls expression of the nitrogen-regulated (ntr) genes in response to nitrogen limitation. Phosphorylated NtrC binds directly to DNA and stimulates the formation of open promoter-sigma54-RNA polymerase complexes.
Belongs to the universal ribosomal protein uL18 family.
Part of the 50S ribosomal subunit; part of the 5S rRNA/L5/L18/L25 subcomplex. Contacts the 5S and 23S rRNAs.
This is one of the proteins that binds and probably mediates the attachment of the 5S RNA into the large ribosomal subunit, where it forms part of the central protuberance.
Prevents the cell division inhibition by proteins MinC and MinD at internal division sites while permitting inhibition at polar sites. This ensures cell division at the proper site by restricting the formation of a division septum at the midpoint of the long axis of the cell.
Bidirectionally degrades single-stranded DNA into large acid-insoluble oligonucleotides, which are then degraded further into small acid-soluble oligonucleotides.
Heterooligomer composed of large and small subunits.
Methylation of the membrane-bound methyl-accepting chemotaxis proteins (MCP) to form gamma-glutamyl methyl ester residues in MCP.
Belongs to the ferredoxin--NADP reductase type 1 family.
Binds 1 Mg(2+) ion per subunit. May bind a second metal ion at a regulatory site, or after substrate binding.
Endonuclease that specifically degrades the RNA of RNA-DNA hybrids.
