STRING protein interaction network
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:
some 3D structure is known or predicted
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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
protein homology
Your Input:
Gene Fusion
dedDCell division protein DedD; Non-essential cell division protein that could be required for efficient cell constriction; Belongs to the DedD family (220 aa)    
Predicted Functional Partners:
Dihydrofolate synthase/folylpolyglutamate synthase; Functions in two distinct reactions of the de novo folate biosynthetic pathway. Catalyzes the addition of a glutamate residue to dihydropteroate (7,8-dihydropteroate or H2Pte) to form dihydrofolate (7,8-dihydrofolate monoglutamate or H2Pte-Glu). Also catalyzes successive additions of L-glutamate to tetrahydrofolate or 10-formyltetrahydrofolate or 5,10-methylenetetrahydrofolate, leading to folylpolyglutamate derivatives
Cell division protein FtsN; Essential cell division protein that activates septal peptidoglycan synthesis and constriction of the cell. Acts on both sides of the membrane, via interaction with FtsA in the cytoplasm and interaction with the FtsQBL complex in the periplasm. These interactions may induce a conformational switch in both FtsA and FtsQBL, leading to septal peptidoglycan synthesis by FtsI and associated synthases (Probable). Required for full FtsI activity. Required for recruitment of AmiC to the septal ring; Belongs to the FtsN family
Cell division protein DamX; Non-essential cell division protein; Belongs to the DamX family
Acetyl-coenzyme A carboxylase carboxyl transferase subunit beta; Component of the acetyl coenzyme A carboxylase (ACC) complex. Biotin carboxylase (BC) catalyzes the carboxylation of biotin on its carrier protein (BCCP) and then the CO(2) group is transferred by the transcarboxylase to acetyl-CoA to form malonyl- CoA; Belongs to the AccD/PCCB family
Endolytic peptidoglycan transglycosylase RlpA; Lytic transglycosylase with a strong preference for naked glycan strands that lack stem peptides; Belongs to the RlpA family
Colicin V production protein; Required for colicin V production from plasmid IncFI ColV3-K30
Cell division activator CedA; Activates the cell division inhibited by chromosomal DNA over-replication
tRNA pseudouridine synthase A; Formation of pseudouridine at positions 38, 39 and 40 in the anticodon stem and loop of transfer RNAs
Amidophosphoribosyltransferase; Catalyzes the formation of phosphoribosylamine from phosphoribosylpyrophosphate (PRPP) and glutamine. Can also use NH(3) in place of glutamine
Guanylate kinase; Essential for recycling GMP and indirectly, cGMP; Belongs to the guanylate kinase family
