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

yaePUPF0253 family protein; Belongs to the UPF0253 family. (66 aa)    
Predicted Functional Partners:
rof
Modulator of Rho-dependent transcription termination; Suppresses temperature-sensitive mutations in essential genes by modulating rho-dependent transcription termination.

nadR
Trifunctional NAD biosynthesis/regulator protein NadR; This enzyme has three activities: DNA binding, nicotinamide mononucleotide (NMN) adenylyltransferase and ribosylnicotinamide (RN) kinase. The DNA-binding domain binds to the nadB operator sequence in an NAD- and ATP-dependent manner. As NAD levels increase within the cell, the affinity of NadR for the nadB operator regions of nadA, nadB, and pncB increases, repressing the transcription of these genes. The RN kinase activity catalyzes the phosphorylation of RN to form nicotinamide ribonucleotide. The NMN adenylyltransferase activity [...]

yaeQ
PDDEXK superfamily protein.
       0.515
arfB
Alternative stalled-ribosome rescue factor B; Rescues stalled ribosomes. Can hydrolyze peptidyl-tRNA on ribosomes stalled by both non-stop mRNAs and mRNAs that contain rare codon clusters or ribosomes stalled in the middle of mRNA. First identified as a complementary ribosome rescue system when the stalled ribosome cannot be rescued by the SsrA(tmRNA)- SmpB quality control system or the alternative ribosome-rescue factor A (arfA).
       0.515
fecC
Ferric citrate ABC transporter permease; Part of the binding-protein-dependent transport system for citrate-dependent Fe(3+). Probably responsible for the translocation of the substrate across the membrane.
