Belongs to the universal ribosomal protein uL3 family.
One of the primary rRNA binding proteins, it binds directly near the 3'-end of the 23S rRNA, where it nucleates assembly of the 50S subunit.
Part of the 50S ribosomal subunit. Forms a cluster with proteins L14 and L19.
Belongs to the prokaryotic ubiquitin-like protein family.
Is modified by deamidation of its C-terminal glutamine to glutamate by the deamidase Dop, a prerequisite to the subsequent pupylation process.
Protein modifier that is covalently attached to lysine residues of substrate proteins, thereby targeting them for proteasomal degradation. The tagging system is termed pupylation.
Strongly interacts with the proteasome-associated ATPase ARC through a hydrophobic interface; the interacting region of Pup lies in its C-terminal half. There is one Pup binding site per ARC hexamer ring.
The N-terminal unstructured half of Pup provides a signal required to initiate unfolding and degradation by the proteasome but is not needed for pupylation, while the C-terminal helical half of Pup interacts with ARC to target proteins to the proteasome.
Belongs to the universal ribosomal protein uL29 family.
The conversion to 3-oxoalanine (also known as C-formylglycine, FGly), of a serine or cysteine residue in prokaryotes and of a cysteine residue in eukaryotes, is critical for catalytic activity.
Belongs to the type-B carboxylesterase/lipase family.
Belongs to the complex I subunit 4L family.
NDH-1 is composed of 14 different subunits. Subunits NuoA, H, J, K, L, M, N constitute the membrane sector of the complex.
NDH-1 shuttles electrons from NADH, via FMN and iron-sulfur (Fe-S) centers, to quinones in the respiratory chain. The immediate electron acceptor for the enzyme in this species is believed to be a menaquinone. Couples the redox reaction to proton translocation (for every two electrons transferred, four hydrogen ions are translocated across the cytoplasmic membrane), and thus conserves the redox energy in a proton gradient.
Belongs to the universal ribosomal protein uS11 family.
Located on the platform of the 30S subunit, it bridges several disparate RNA helices of the 16S rRNA. Forms part of the Shine-Dalgarno cleft in the 70S ribosome.
Part of the 30S ribosomal subunit. Interacts with proteins S7 and S18. Binds to IF-3.
Belongs to the bacterial ribosomal protein bL34 family.
Belongs to the bacterial ribosomal protein bL33 family.
Acts as a transcriptional regulator. Probably redox-responsive. The apo- but not holo-form probably binds DNA.
Binds 1 [4Fe-4S] cluster per subunit. Following nitrosylation of the [4Fe-4S] cluster binds 1 [4Fe-8(NO)] cluster per subunit.
The Fe-S cluster can be nitrosylated by nitric oxide (NO).
Upon Fe-S cluster removal intramolecular disulfide bonds are formed.
Can catalyze the hydrolysis of ATP in the presence of single-stranded DNA, the ATP-dependent uptake of single-stranded DNA by duplex DNA, and the ATP-dependent hybridization of homologous single-stranded DNAs. It interacts with LexA causing its activation and leading to its autocatalytic cleavage.
F(1)F(0) ATP synthase produces ATP from ADP in the presence of a proton or sodium gradient. F-type ATPases consist of two structural domains, F(1) containing the extramembraneous catalytic core and F(0) containing the membrane proton channel, linked together by a central stalk and a peripheral stalk. During catalysis, ATP synthesis in the catalytic domain of F(1) is coupled via a rotary mechanism of the central stalk subunits to proton translocation.
Key component of the F(0) channel; it plays a direct role in translocation across the membrane. A homomeric c-ring of between 10-14 subunits forms the central stalk rotor element with the F(1) delta and epsilon subunits.
Belongs to the universal ribosomal protein uS10 family.
Involved in the binding of tRNA to the ribosomes.
Belongs to the non-flavoprotein flavin reductase family.
Component of the 30S ribosomal translation pre-initiation complex which assembles on the 30S ribosome in the order IF-2 and IF-3, IF-1 and N-formylmethionyl-tRNA(fMet); mRNA recruitment can occur at any time during PIC assembly.
One of the essential components for the initiation of protein synthesis. Stabilizes the binding of IF-2 and IF-3 on the 30S subunit to which N-formylmethionyl-tRNA(fMet) subsequently binds. Helps modulate mRNA selection, yielding the 30S pre-initiation complex (PIC). Upon addition of the 50S ribosomal subunit IF-1, IF-2 and IF-3 are released leaving the mature 70S translation initiation complex.
Belongs to the bacterial ribosomal protein bS18 family.
Binds as a heterodimer with protein S6 to the central domain of the 16S rRNA, where it helps stabilize the platform of the 30S subunit.
Part of the 30S ribosomal subunit. Forms a tight heterodimer with protein S6.
Belongs to the enoyl-CoA hydratase/isomerase family.
Belongs to the universal ribosomal protein uL16 family.
Binds 23S rRNA and is also seen to make contacts with the A and possibly P site tRNAs.
Belongs to the acyl-CoA dehydrogenase family.
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.
