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

Rv0203Possible exported protein; Part of a heme-iron acquisition system. Acts by binding heme and delivering it to the membrane proteins MmpL3 and MmpL11. Can use free heme or heme from host hemoglobin. (136 aa)    
Predicted Functional Partners:
mmpL11
Probable conserved transmembrane transport protein MmpL11; Part of a heme-iron acquisition system. Receives heme from the heme-binding protein Rv0203 and transports it into the mycobacterial cell. Contributes to virulence. Belongs to the resistance-nodulation-cell division (RND) (TC 2.A.6) family. MmpL subfamily.
  
  
 0.875
mhuD
Possible heme degrading protein MhuD; Catalyzes the oxidative degradation of the heme macrocyclic porphyrin ring in the presence of a suitable electron donor such as ascorbate or NADPH--cytochrome P450 reductase, with subsequent release of free iron.
