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

norRTranscriptional regulator; Required for the expression of anaerobic nitric oxide (NO) reductase; acts as a transcriptional activator for the norVW operon; Derived by automated computational analysis using gene prediction method: Protein Homology. (514 aa)    
Predicted Functional Partners:
rpoN
RNA polymerase factor sigma-54; Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is responsible for the expression of the nitrogen fixation genes. The open complex (sigma-54 and core RNA polymerase) serves as the receptor for receipt of the melting signal from the remotely bound activator protein NifA for the expression of the nitrogen fixation proteins.

norV
Nitric oxide reductase; Anaerobic nitric oxide reductase; uses NADH to detoxify nitric oxide (NO), protecting several 4Fe-4S NO-sensitive enzymes. Has at least 2 reductase partners, only one of which (NorW, flavorubredoxin reductase) has been identified. NO probably binds to the di-iron center; electrons enter from the NorW at rubredoxin and are transferred sequentially to the FMN center and the di-iron center. Also able to function as an aerobic oxygen reductase; In the N-terminal section; belongs to the zinc metallo- hydrolase group 3 family.

hmp
Dihydropteridine reductase; Is involved in NO detoxification in an aerobic process, termed nitric oxide dioxygenase (NOD) reaction that utilizes O(2) and NAD(P)H to convert NO to nitrate, which protects the bacterium from various noxious nitrogen compounds. Therefore, plays a central role in the inducible response to nitrosative stress; Belongs to the globin family. Two-domain flavohemoproteins subfamily.
     
 0.458
pspA
Phage shock protein; Involved in maintaining membrane potential under membrane stress conditions; also acts as a negative transcriptional regulator of the phage shock protein (psp) operon(pspABCDE) by regulating the transcriptional activator PspF; Derived by automated computational analysis using gene prediction method: Protein Homology.
     
 0.431
AKL38932.1
Transcriptional regulator; Represses the modABCD operon and activates the moaABCD and napFDAGHBC operons; Derived by automated computational analysis using gene prediction method: Protein Homology.
