STRINGSTRING
dps protein (Synechococcus elongatus PCC7942) - STRING interaction network
"dps" - DNA protection during starvation protein in Synechococcus elongatus PCC7942
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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

dpsDNA protection during starvation protein; Protects DNA from oxidative damage by sequestering intracellular Fe(2+) ion and storing it in the form of Fe(3+) oxyhydroxide mineral. One hydrogen peroxide oxidizes two Fe(2+) ions, which prevents hydroxyl radical production by the Fenton reaction (By similarity). Dps binds the chromosome non- specifically, forming a highly ordered and stable dps-DNA co- crystal within which chromosomal DNA is condensed and protected from diverse damages. Soluble dps might function in iron homeostasis under high iron concentration, while the dps-DNA complex mi [...] (176 aa)    
Predicted Functional Partners:
srpA
Catalase-related peroxidase; Has an organic peroxide-dependent peroxidase activity (365 aa)
 
   
  0.780
hemE
Uroporphyrinogen decarboxylase; Catalyzes the decarboxylation of four acetate groups of uroporphyrinogen-III to yield coproporphyrinogen-III (354 aa)
           
  0.714
irpA
Iron-regulated protein A; IrpA occurs under iron-deficient growth conditions in cyanobacterium Synechococcus and disappears in cells recovering from iron starvation. It seems to be involved in iron acquisition, uptake or storage (356 aa)
