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

ccmA
Heme exporter protein CcmA; Part of the ABC transporter complex CcmAB involved in the biogenesis of c-type cytochromes; once thought to export heme, this seems not to be the case, but its exact role is uncertain. Responsible for energy coupling to the transport system; Belongs to the ABC transporter superfamily. CcmA exporter (TC 3.A.1.107) family.
  
  
 
0.908
Pnap_1142
PFAM: periplasmic solute binding protein; KEGG: rfr:Rfer_2051 periplasmic solute binding protein; Belongs to the bacterial solute-binding protein 9 family.
 
  
 0.866
ccmC
Heme exporter protein CcmC; Required for the export of heme to the periplasm for the biogenesis of c-type cytochromes; Belongs to the CcmC/CycZ/HelC family.
  
 
  0.806
Pnap_0588
Heme exporter protein CcmB; Required for the export of heme to the periplasm for the biogenesis of c-type cytochromes; Belongs to the CcmB/CycW/HelB family.

ffh
Signal recognition particle subunit FFH/SRP54 (srp54); Involved in targeting and insertion of nascent membrane proteins into the cytoplasmic membrane. Binds to the hydrophobic signal sequence of the ribosome-nascent chain (RNC) as it emerges from the ribosomes. The SRP-RNC complex is then targeted to the cytoplasmic membrane where it interacts with the SRP receptor FtsY. Interaction with FtsY leads to the transfer of the RNC complex to the Sec translocase for insertion into the membrane, the hydrolysis of GTP by both Ffh and FtsY, and the dissociation of the SRP-FtsY complex into the i [...]

ftsY
Signal recognition particle-docking protein FtsY; Involved in targeting and insertion of nascent membrane proteins into the cytoplasmic membrane. Acts as a receptor for the complex formed by the signal recognition particle (SRP) and the ribosome-nascent chain (RNC). Interaction with SRP-RNC leads to the transfer of the RNC complex to the Sec translocase for insertion into the membrane, the hydrolysis of GTP by both Ffh and FtsY, and the dissociation of the SRP-FtsY complex into the individual components.

Pnap_1703
Signal transduction histidine kinase with CheB and CheR activity; Involved in chemotaxis. Part of a chemotaxis signal transduction system that modulates chemotaxis in response to various stimuli. Catalyzes the demethylation of specific methylglutamate residues introduced into the chemoreceptors (methyl-accepting chemotaxis proteins or MCP) by CheR. Also mediates the irreversible deamidation of specific glutamine residues to glutamic acid. Belongs to the CheB family.

hflX
GTP-binding protein HflX; GTPase that associates with the 50S ribosomal subunit and may have a role during protein synthesis or ribosome biogenesis. Belongs to the TRAFAC class OBG-HflX-like GTPase superfamily. HflX GTPase family.
