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

CC_1741Nitrogen regulation protein NR(I); Identified by match to protein family HMM. (473 aa)    
Predicted Functional Partners:
CC_1740
Nitrogen regulation protein NR(II); Identified by match to protein family HMM.
 0.999
CC_3579
Transcriptional regulator, internal deletion; Similar to GB:M90471 SP:P28614 PID:141888; identified by sequence similarity; putative.

rpoN
RNA polymerase sigma-54 factor; 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. This sigma factor is required for the de novo biogenesis of both flagellum and stalk, and for polar morphogenesis and normal cell division. It may not be involved in nitrogen assimilation.
