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

irgAIron-regulated outer membrane virulence protein, TonB receptor family; Involved in the initial step of iron uptake by binding ferric vibriobactin, an iron chelatin siderophore that allows V.cholerae to extract iron from the environment; Belongs to the TonB-dependent receptor family. (652 aa)    
Predicted Functional Partners:
tonB
tonB1 protein; Interacts with outer membrane receptor proteins that carry out high-affinity binding and energy dependent uptake into the periplasmic space of specific substrates. It could act to transduce energy from the cytoplasmic membrane to specific energy-requiring processes in the outer membrane, resulting in the release into the periplasm of ligands bound by these outer membrane proteins (By similarity).

VC_1544
tonB2 protein; Interacts with outer membrane receptor proteins that carry out high-affinity binding and energy dependent uptake into the periplasmic space of specific substrates. It could act to transduce energy from the cytoplasmic membrane to specific energy-requiring processes in the outer membrane, resulting in the release into the periplasm of ligands bound by these outer membrane proteins. Belongs to the TonB family.

viuA
Ferric vibriobactin receptor; Receptor for ferric vibriobactin; Belongs to the TonB-dependent receptor family.

VC_0414
Hypothetical protein; Identified by Glimmer2; putative.
   
 
 0.867
vibB
Vibriobactin-specific isochorismatase; Involved in the biosynthesis of the catechol siderophore vibriobactin. Vibriobactin is a chelating compound involved in transporting iron from the bacterial environment into the cell cytoplasm; Belongs to the isochorismatase family.
 
  
 0.859
irgB
Iron-regulated virulence regulatory protein IrgB; Transcription activation of the irgA gene. In the presence of sufficient iron, transcription of both irgA and irgB is negatively regulated by a fur-like protein. In low iron conditions, negative regulation of transcription is removed, and production of irgB leads to positive transcriptional activation of irgA (By similarity).

VC_0775
Vibriobactin synthesis protein, putative; Similar to GB:M60177 SP:P11454 GB:M17354 PID:145843 PID:551801; identified by sequence similarity; putative.

epd
D-erythrose 4-phosphate dehydrogenase; Catalyzes the NAD-dependent conversion of D-erythrose 4- phosphate to 4-phosphoerythronate.
     
 0.788
VC_A0576
Heme transport protein HutA; Similar to GB:L27149 PID:529727; identified by sequence similarity; putative.

VC_0200
iron(III) compound receptor; Similar to GB:D26562 SP:P06971 GB:M12486 PID:145949 PID:473809; identified by sequence similarity; putative.
