Antenna complexes are light-harvesting systems, which transfer the excitation energy to the reaction centers.
Belongs to the antenna complex beta subunit family.
The core complex is formed by different alpha and beta chains, binding bacteriochlorophyll molecules, and arranged most probably in tetrameric structures disposed around the reaction center. The non-pigmented gamma chains may constitute additional components.
Belongs to the bacterial ribosomal protein bL36 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 binding-protein-dependent transport system permease family.
Heptamer of 7 subunits arranged in a ring. Interacts with the chaperonin GroEL.
Together with the chaperonin GroEL, plays an essential role in assisting protein folding. The GroEL-GroES system forms a nano-cage that allows encapsulation of the non-native substrate proteins and provides a physical environment optimized to promote and accelerate protein folding. GroES binds to the apical surface of the GroEL ring, thereby capping the opening of the GroEL channel.
Belongs to the HicA mRNA interferase family.
Belongs to the bacterial ribosomal protein bL35 family.
Functions as a ribosomal silencing factor. Interacts with ribosomal protein uL14 (rplN), blocking formation of intersubunit bridge B8. Prevents association of the 30S and 50S ribosomal subunits and the formation of functional ribosomes, thus repressing translation.
Interacts with ribosomal protein uL14 (rplN).
Belongs to the binding-protein-dependent transport system permease family. HisMQ subfamily.
Belongs to the reaction center PufL/M/PsbA/D family.
The reaction center is a membrane-bound complex that mediates the initial photochemical event in the electron transfer process of photosynthesis.
Ferredoxins are iron-sulfur proteins that transfer electrons in a wide variety of metabolic reactions.
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 CPA3 antiporters (TC 2.A.63) subunit E family.
Part of the ABC transporter complex UgpBAEC involved in sn-glycerol-3-phosphate (G3P) import. Probably responsible for the translocation of the substrate across the membrane.
The complex is composed of two ATP-binding proteins (UgpC), two transmembrane proteins (UgpA and UgpE) and a solute-binding protein (UgpB).
Belongs to the TRAP transporter large permease family.
Part of the tripartite ATP-independent periplasmic (TRAP) transport system.
The complex comprises the extracytoplasmic solute receptor protein and the two transmembrane proteins.
4'-phosphopantetheine is transferred from CoA to a specific serine of apo-ACP by AcpS. This modification is essential for activity because fatty acids are bound in thioester linkage to the sulfhydryl of the prosthetic group.
Belongs to the acyl carrier protein (ACP) family.
Carrier of the growing fatty acid chain in fatty acid biosynthesis.
Membrane-anchoring subunit of succinate dehydrogenase (SDH).
Part of an enzyme complex containing four subunits: a flavoprotein, an iron-sulfur protein, plus two membrane-anchoring proteins, SdhC and SdhD.
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 ubiquinone. 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.
Reaction center is composed of four bacteriochlorophylls, two bacteriopheophytins, two ubiquinones, one iron, and highly hydrophobic polypeptide chains.
Belongs to the complex I 23 kDa subunit family.
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 complex I subunit 1 family.
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 ubiquinone. 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. This subunit may bind ubiquinone.
Belongs to the bacterial solute-binding protein 3 family.
