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

phsBHydrogen sulfide production iron-sulfur subunit; Component of the PhsABC thiosulfate reductase that catalyzes the reduction of thiosulfate to sulfite and hydrogen sulfide, with menaquinol as the sole electron donor. Proton motive force (PMF) is required to drive transmembrane electron transfer within the reductase. The PhsB subunit transfers electrons between PhsC and PhsA. (192 aa)    
Predicted Functional Partners:
phsC
Hydrogen sulfide production membrane anchoring protein; Component of the PhsABC thiosulfate reductase that catalyzes the reduction of thiosulfate to sulfite and hydrogen sulfide, with menaquinol as the sole electron donor. Proton motive force (PMF) is required to drive transmembrane electron transfer within the reductase. The PhsC subunit anchors the complex to the membrane and contains the site for menaquinol oxidation.

phsA
Hydrogen sulfide production membrane anchoring protein; Component of the PhsABC thiosulfate reductase that catalyzes the reduction of thiosulfate to sulfite and hydrogen sulfide, with menaquinol as the sole electron donor. Proton motive force (PMF) is required to drive transmembrane electron transfer within the reductase. The PhsA subunit contains the active site molybdenum-bis(molybdopterin guanine dinucleotide) (Mo-bis-MGD) cofactor.
 0.999
ttrA
Tetrathionate reductase complex, subunit A; Part of a membrane-bound tetrathionate reductase that catalyzes the reduction of tetrathionate to thiosulfate. TtrA is the catalytic subunit. During mice infection, the ability to use tetrathionate as an electron acceptor is a growth advantage for S.typhimurium over the competing microbiota in the lumen of the inflamed gut; Belongs to the prokaryotic molybdopterin-containing oxidoreductase family.
 
 0.986
asrA
Anaerobic sulfide reductase; Electron transfer protein for anaerobic sulfite reductase subunit A.
  
 
 0.949
asrC
Anaerobic sulfide reductase; This enzyme catalyzes the hydrogen sulfide production from sulfite. It is strictly anaerobic. It is regulated by electron acceptors rather than by cysteine; Belongs to the nitrite and sulfite reductase 4Fe-4S domain family.
  
 
 0.939
ttrC
Tetrathionate reductase complex, subunit C; Part of a membrane-bound tetrathionate reductase that catalyzes the reduction of tetrathionate to thiosulfate. TtrC probably anchors TtrA and TtrB to the periplasmic face of the cytoplasmic membrane. May transfer electrons from membrane quinol to TtrB. During mice infection, the ability to use tetrathionate as an electron acceptor is a growth advantage for S.typhimurium over the competing microbiota in the lumen of the inflamed gut. Belongs to the NrfD family.
  
 
 0.931
cysJ
Sulfite reductase, beta (flavoprotein) subunit; Component of the sulfite reductase complex that catalyzes the 6-electron reduction of sulfite to sulfide. This is one of several activities required for the biosynthesis of L-cysteine from sulfate. The flavoprotein component catalyzes the electron flow from NADPH -> FAD -> FMN to the hemoprotein component; Belongs to the NADPH-dependent sulphite reductase flavoprotein subunit CysJ family. In the C-terminal section; belongs to the flavoprotein pyridine nucleotide cytochrome reductase family.
    
 0.922
ttrB
Tetrathionate reductase complex, subunit B; Part of a membrane-bound tetrathionate reductase that catalyzes the reduction of tetrathionate to thiosulfate. TtrB is probably involved in transfer of electrons from TtrC to TtrA. During mice infection, the ability to use tetrathionate as an electron acceptor is a growth advantage for S.typhimurium over the competing microbiota in the lumen of the inflamed gut.

asrB
Anaerobic sulfide reductase; This enzyme catalyzes the hydrogen sulfide production from sulfite. It is strictly anaerobic. It is regulated by electron acceptors rather than by cysteine.
