STRING protein interaction network
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 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
protein homology

Gene Fusion
asnCTranscriptional activator of asnA; Activator of asnA transcription; autogenous regulator of its own transcription; and repressor of the expression of gidA at a post- transcriptional level. (152 aa)    
Predicted Functional Partners:
Transcriptional repressor of multiple antibiotic resistance; Repressor of the marRAB operon which is involved in the activation of both antibiotic resistance and oxidative stress genes. Binds to the marO operator/promoter site.
Putative DNA-binding transcriptional regulator; Plays a role in L-cysteine detoxification. Binds to the dlsT(yhaO)-yhaM operon promoter in the presence but not absence of L- cysteine; activates transcription from the dlsT(yhaO)-yhaM operon. No other DNA target was identified in strain K12 / BW25113. Thiosulfate does not activate its transcription function. Overexpression doubles hydrogen sulfide production in the presence of cysteine.
Asparagine synthetase A; May amidate Asp of the extracellular death factor precursor Asn-Asn-Trp-Asp-Asn to generate Asn-Asn-Trp-Asn-Asn.
FMN-binding protein MioC; Probable electron transporter required for biotin synthase activity.
D-gluconate inducible gluconate regulon transcriptional repressor; Negative regulator for the gluconate utilization system GNT- I, the gntUKR operon.
Arsenical resistance operon transcriptional repressor; Transcriptional repressor for the arsEFG operon. ArsE is a trans-acting regulatory protein which controls its own expression. The repressive effect of ArsE is alleviated by oxyions of +III oxidation state of arsenic, antimony, and bismuth, as well as arsenate (As(V)) (By similarity).
Hexuronate isomerase; Catalyzes the isomerization of 5-dehydro-4-deoxy-D- glucuronate to 3-deoxy-D-glycero-2,5-hexodiulosonate (By similarity). Plays a role in the catabolism of hexuronates under osmotic stress conditions, likely substituting for the regular hexuronate degrading enzyme UxaC whose expression is repressed in these conditions ; Belongs to the KduI family.
Ara regulon transcriptional activator; Transcription factor that regulates the expression of several genes involved in the transport and metabolism of L-arabinose. Functions both as a positive and a negative regulator. In the presence of arabinose, activates the expression of the araBAD, araE, araFGH and araJ promoters. In the absence of arabinose, negatively regulates the araBAD operon. Represses its own transcription. Acts by binding directly to DNA.
DNA topoisomerase IV, subunit A; Topoisomerase IV is essential for chromosome segregation; it is the principal protein responsible for decatenating newly replicated chromosomes. It relaxes supercoiled DNA. MukB stimulates the relaxation activity of topoisomerase IV and also has a modest effect on decatenation. Belongs to the type II topoisomerase GyrA/ParC subunit family. ParC type 1 subfamily.
PDDEXK superfamily protein.
