STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

ccoQCbb3-type cytochrome oxidase, subunit ccoQ, 44% Identity to TrEMBL;Q8D9I3, Q7MKV5,Q9KS21. Has PF05545,Cbb3-type cytochrome oxidase component FixQ; IPR008621;This family consists of several Cbb3-type cytochrome oxidase components (FixQ/CcoQ). FixQ is found in nitrogen fixing bacteria. Since nitrogen fixation is an energy-consuming process, effective symbioses depend on operation of a respiratory chain with a high affinity for O2, closely coupled to ATP production. This requirement is fulfilled by a special three-subunit terminal oxidase (cytochrome terminal oxidase cbb3), which was firs [...] (57 aa)

azo3085
Conserved hypothetical membrane protein. Homology to CV2709 of Chromobacterium violaceum of 40% (trembl|Q7NUI9). Has PF04550;Phage holin family 2:Holins are a diverse family of proteins that cause bacterial membrane lysis during late-protein synthesis. It is thought that the temporal precision of holin-mediated lysis may occur through the buildup of a holin oligomer which causes the lysis. IPR007633;Phage_holin_2. TMHMM2 reporting 12 TMH's Present. no signal peptide; Conserved hypothetical protein.

ccoG
Putative iron-sulfur 4Fe-4S ferredoxin transmembrane protein. Homology to fixG of R. meliloti of 36% (FIXG_RHIME). Ferredoxins are iron-sulphur proteins that mediate electron transfer in a range of metabolic reactions; they fall into several subgroups according to the nature of their iron-sulphur cluster(s). One group,originally found in bacteria, has been termed ''bacterial-type'', in which the active centre is a 4Fe-4S cluster. 4Fe-4S ferredoxins may in turn be subdivided into further groups, based on their sequence properties. Most contain at least one conserved domain, including fo [...]

Conserved hypothetical membrane protein. Homology to ebA5136 Azoarcus sp. EbN1 of 51% (gnl|keqq|eba:ebA5136(KEGG)). Has PF05751, FixH;IPR008620; This family consists of several Rhizobium FixH like proteins. It has been suggested that suggested that the four proteins FixG, FixH, FixI, and FixS may participate in a membrane-bound complex coupling the FixI cation pump with a redox process catalysed by FixG.

ccoS
Conserved hypothetical cytochrome oxidase maturation protein. Homology to cco of P.Putida of 42% (gnl|keqq|ppu:PP4262(KEGG)). Pfam: Cytochrome oxidase maturation protein cbb3-type. Genes encoding a cytochrome cbb3 oxidase were initially designated fixNOQP (ccoNOQP),the ccoNOQP operon is always found close to a second gene cluster, known as fixGHIS (ccoGHIS) whose expression is necessary for the assembly of a functional cbb3 oxidase. On the basis of their derived amino acid sequences each of the four proteins encoded by the ccoGHIS operon are thought to be membrane-bound. It has been su [...]
