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

Score
putPSSS family major sodium/proline symporter; Catalyzes the sodium-dependent uptake of extracellular L- proline; Belongs to the sodium:solute symporter (SSF) (TC 2.A.21) family. (502 aa)    
Predicted Functional Partners:
putA
Plasma membrane proline dehydrogenase; Oxidizes proline to glutamate for use as a carbon and nitrogen source and also function as a transcriptional repressor of the put operon; In the C-terminal section; belongs to the aldehyde dehydrogenase family.
  
  
 0.999
pabB
P-aminobenzoate synthetase, component I; Part of a heterodimeric complex that catalyzes the two-step biosynthesis of 4-amino-4-deoxychorismate (ADC), a precursor of p- aminobenzoate (PABA) and tetrahydrofolate. In the first step, a glutamine amidotransferase (PabA) generates ammonia as a substrate that, along with chorismate, is used in the second step, catalyzed by aminodeoxychorismate synthase (PabB) to produce ADC (By similarity).
      
 0.899
trpB
Tryptophan synthase, beta protein; The beta subunit is responsible for the synthesis of L- tryptophan from indole and L-serine; Belongs to the TrpB family.
      
 0.898
proP
MFS family low-affinity proline transporter; Proton symporter that senses osmotic shifts and responds by importing osmolytes such as proline, glycine betaine, stachydrine, pipecolic acid, ectoine and taurine. It is both an osmosensor and an osmoregulator which is available to participate early in the bacterial osmoregulatory response (By similarity); Belongs to the major facilitator superfamily. Metabolite:H+ Symporter (MHS) family (TC 2.A.1.6) family.
   
  
 0.864
trpA
Tryptophan synthase, alpha protein; The alpha subunit is responsible for the aldol cleavage of indoleglycerol phosphate to indole and glyceraldehyde 3-phosphate.
      
 0.810
yaaJ
AGCS family; similar to E. coli inner membrane transport protein (AAC73118.1); Blastp hit to AAC73118.1 (476 aa), 76% identity in aa 1 - 476.
  
  
 0.766
STM1003
Putative transcriptional regulator, Lrp family; Similar to E. coli inner membrane transport protein (AAC73118.1); Blastp hit to AAC73118.1 (476 aa), 30% identity in aa 12 - 430.
  
  
 0.764
dinP
DNA polymerase IV; Poorly processive, error-prone DNA polymerase involved in untargeted mutagenesis. Copies undamaged DNA at stalled replication forks, which arise in vivo from mismatched or misaligned primer ends. These misaligned primers can be extended by PolIV. Exhibits no 3'-5' exonuclease (proofreading) activity. May be involved in translesional synthesis, in conjunction with the beta clamp from PolIII.
      
 0.700
polB
DNA polymerase II; 3'->5' exonuclease; similar to E. coli DNA polymerase II (AAC73171.1); Blastp hit to AAC73171.1 (783 aa), 89% identity in aa 1 - 783.
      
 0.698
proY
Putative APC family, proline transporter; Permease that is involved in the transport across the cytoplasmic membrane of proline; Belongs to the amino acid-polyamine-organocation (APC) superfamily. Amino acid transporter (AAT) (TC 2.A.3.1) family.
