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:
some 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

ihfBIntegration host factor (ihf), dna-binding protein, beta subunit; One of the 2 subunits of integration host factor (IHF), a specific DNA-binding protein that functions in genetic recombination as well as in transcriptional and translational control. Has an essential role in conjugative DNA transfer (CDT), the unidirectional transfer of ssDNA plasmid from a donor to a recipient cell. It is the central mechanism by which antibiotic resistance and virulence factors are propagated in bacterial populations. Part of the relaxosome, which facilitates a site- and strand-specific cut in the ori [...] (94 aa)

ihfA
Integration host factor (ihf), dna-binding protein, alpha subunit; One of the 2 subunits of integration host factor (IHF), a specific DNA-binding protein that functions in genetic recombination as well as in transcriptional and translational control. Binds to hundreds of transcriptionally inactive, AT-rich DNA sites, approximately half its binding sites are in non-coding DNA, which only accounts for about 10% of the genome . Has an essential role in conjugative DNA transfer (CDT), the unidirectional transfer of ssDNA plasmid from a donor to a recipient cell. It is the central mechanism [...]

rpsA
Required for translation of most natural mRNAs except for leaderless mRNA Binds mRNA upstream of the Shine- Dalgarno (SD) sequence and helps it bind to the 30S ribosomal subunit; acts as an RNA chaperone to unfold structured mRNA on the ribosome but is not essential for mRNAs with strong SDs and little 5'-UTR structure, thus it may help fine-tune which mRNAs that are translated . Unwinds dsRNA by binding to transiently formed ssRNA regions; binds about 10 nucleotides . Has a preference for polypyrimidine tracts . Negatively autoregulates its own translation . In case of infection by ba [...]

cmk
Cytidylate kinase; ATP, dATP, and GTP are equally effective as phosphate donors. CMP and dCMP are the best phosphate acceptors

lpxK
Tetraacyldisaccharide 4'-kinase; Transfers the gamma-phosphate of ATP to the 4'-position of a tetraacyldisaccharide 1-phosphate intermediate (termed DS-1-P) to form tetraacyldisaccharide 1,4'-bis-phosphate (lipid IVA)

ygbF
CRISPR (clustered regularly interspaced short palindromic repeat), is an adaptive immune system that provides protection against mobile genetic elements (viruses, transposable elements and conjugative plasmids) . CRISPR clusters contain sequences complementary to antecedent mobile elements and target invading nucleic acids. CRISPR clusters are transcribed and processed into CRISPR RNA (crRNA). The Cas1-Cas2 complex is involved in CRISPR adaptation, the first stage of CRISPR immunity, being required for the addition/removal of CRISPR spacers at the leader end of the CRISPR locus . The C [...]

fis
Fis family transcriptional regulator, factor for inversion stimulation protein; Activates ribosomal RNA transcription, as well other genes. Plays a direct role in upstream activation of rRNA promoters. Binds to a recombinational enhancer sequence that is required to stimulate hin- mediated DNA inversion. Prevents initiation of DNA replication from oriC. Binds to hundreds of transcriptionally active and inactive AT- rich sites, approximately half its binding sites are in non-coding DNA, which only accounts for about 10% of the genome

gyrA
A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to maintain chromosomes in an underwound state This makes better substrates for topoisomerase IV (ParC and ParE) which is the main enzyme that unlinks newly replicated chromosomes in E.coli . Gyrase catalyzes the interconversion of other topological isomers of dsDNA rings, including catenanes . Relaxes negatively supercoiled DNA in an ATP-independent manner . E.coli gyrase has higher supercoiling activity than many other bacterial gyrases; at comparable concentrations [...]

serC
3-phosphoserine/phosphohydroxythreonine aminotransferase; Catalyzes the reversible conversion of 3- phosphohydroxypyruvate to phosphoserine and of 3-hydroxy-2-oxo-4- phosphonooxybutanoate to phosphohydroxythreonine. Is involved in both pyridoxine and serine biosynthesis
