STRINGSTRING
isiB protein (Synechococcus elongatus PCC7942) - STRING interaction network
"isiB" - Flavodoxin 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

isiBFlavodoxin; Low-potential electron donor to a number of redox enzymes (170 aa)    
Predicted Functional Partners:
isiA
Iron stress-induced chlorophyll-binding protein; Functions as an antenna for photosystem I (PSI) under iron-limiting conditions, when phycobilisomes disappear. Also functions as a dissipator of light energy, protecting cells from excessive light under iron-deficient conditions. Sequesters chlorophyll when cells are growing in iron-deficient conditions; it may bind up to 50% of the chlorophyll in iron-starved cells (342 aa)

psaC
Photosystem I iron-sulfur center; Apoprotein for the two 4Fe-4S centers FA and FB of photosystem I (PSI); essential for photochemical activity. FB is the terminal electron acceptor of PSI, donating electrons to ferredoxin. The C-terminus interacts with PsaA/B/D and helps assemble the protein into the PSI complex. Required for binding of PsaD and PsaE to PSI. PSI is a plastocyanin/cytochrome c6- ferredoxin oxidoreductase, converting photonic excitation into a charge separation, which transfers an electron from the donor P700 chlorophyll pair to the spectroscopically characterized accept [...] (81 aa)

petC
Cytochrome b6-f complex iron-sulfur subunit; Component of the cytochrome b6-f complex, which mediates electron transfer between photosystem II (PSII) and photosystem I (PSI), cyclic electron flow around PSI, and state transitions (179 aa)
           
  0.731
ABB58414.1
Pyruvate-flavodoxin oxidoreductase; Oxidoreductase required for the transfer of electrons from pyruvate to flavodoxin (1196 aa)
   
   
  0.691
ABB56768.1
annotation not available (103 aa)

hemE
Uroporphyrinogen decarboxylase; Catalyzes the decarboxylation of four acetate groups of uroporphyrinogen-III to yield coproporphyrinogen-III (354 aa)
