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

apaGapaG protein; Identified by similarity to SP:Q56017; match to protein family HMM PF04379. (126 aa)    
Predicted Functional Partners:
apaH
Bis(5'-nucleosyl)-tetraphosphatase, symmetrical; Hydrolyzes diadenosine 5',5'''-P1,P4-tetraphosphate to yield ADP; Belongs to the Ap4A hydrolase family.
  
  
 0.791
ksgA
Dimethyladenosine transferase; Specifically dimethylates two adjacent adenosines (A1518 and A1519) in the loop of a conserved hairpin near the 3'-end of 16S rRNA in the 30S particle. May play a critical role in biogenesis of 30S subunits.
  
  
 0.757
MCA0240
Conserved hypothetical protein; Identified by similarity to OMNI:NTL03PA00760; match to protein family HMM PF01571; Belongs to the GcvT family.
 
    0.702
clpP-1
ATP-dependent Clp protease, proteolytic subunit ClpP; Cleaves peptides in various proteins in a process that requires ATP hydrolysis. Has a chymotrypsin-like activity. Plays a major role in the degradation of misfolded proteins. Belongs to the peptidase S14 family.
