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

MCA0225Rieske 2Fe-2S family protein; Identified by similarity to GP:1754625; match to protein family HMM PF00355. (108 aa)    
Predicted Functional Partners:
MCA0431
Flavodoxin domain protein; 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.

MCA0586
Rieske 2Fe-2S family protein; Identified by similarity to GP:1754625; match to protein family HMM PF00355.
  
  
 
0.911
MCA2059
Nitrite/sulfite reductase protein; Identified by match to protein family HMM PF01077; match to protein family HMM PF03460.
     
 0.905
cysH
Phosophoadenylyl-sulfate reductase; Reduction of activated sulfate into sulfite.
     
 0.902
sseA
Mercaptopyruvate sulfurtransferase; Identified by similarity to GP:6009981; match to protein family HMM PF00581.
    
  0.900
cysG
Siroheme synthase; Multifunctional enzyme that catalyzes the SAM-dependent methylations of uroporphyrinogen III at position C-2 and C-7 to form precorrin-2 via precorrin-1. Then it catalyzes the NAD-dependent ring dehydrogenation of precorrin-2 to yield sirohydrochlorin. Finally, it catalyzes the ferrochelation of sirohydrochlorin to yield siroheme.
