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

feoCProbable [Fe-S]-dependent transcriptional repressor FeoC; May function as a transcriptional regulator that controls feoABC expression (78 aa)    
Predicted Functional Partners:
Fe(2+) transporter FeoB; Transporter of a GTP-driven Fe(2+) uptake system, probably couples GTP-binding to channel opening and Fe(2+) uptake. A guanine nucleotide-binding protein (G proteins) in which the guanine nucleotide binding site alternates between an active, GTP-bound state and an inactive, GDP-bound state. This protein has fast intrinsic GDP release, mediated by the G5 loop (about residues 149-158). Presumably GTP hydrolysis leads to conformational changes and channel closing. A GDP release mechanism involving a conformational change of the G5 loop (and thus the removal of the [...]
Fe(2+) transport protein A; Involved in Fe(2+) ion uptake. Does not stimulate the GTPase activity of the N-terminus of FeoB (residues 1-276)
Recombination-promoting nuclease RpnA; A low activity DNA endonuclease yielding 3'-hydroxyl ends, equally active on ss or dsDNA, not active on dsRNA. Shows no sequence specificity. Upon expression enhances RecA-independent DNA recombination 49-fold, concomitantly reducing viability by 88% and probably inducing DNA damage as measured by induction of the SOS repair response in RecA cells. RecA-independent DNA recombination leads to replacement of recipient genes with large segments of donor DNA rather than DNA addition to the donor strain; increased expression of RpnA leads to smaller re [...]
Diaminopropionate ammonia-lyase; Catalyzes the alpha,beta-elimination reaction of both L- and D-alpha,beta-diaminopropionate (DAP) to form pyruvate and ammonia. In vitro the D-isomer of serine is degraded to pyruvate, though very poorly; other amino acids (L-serine, D- and L- threonine, D- and L-beta-Cl-alanine) are not substrates. In vivo allows poor growth on L-DAP or a DL-DAP mixture but not on D-DAP alone, this may be due to a poor promoter. DL-DAP is toxic in the absence of this enzyme, it may inhibit enzymes involved in the synthesis of pyruvate and aspartate, as well as amino ac [...]
L-fucose isomerase; Converts the aldose L-fucose into the corresponding ketose L-fuculose. Is also able to convert D-arabinose into D- ribulose, but this isomerase has a higher affinity for fucose and fuculose than for arabinose and ribulose, respectively
Methylmalonyl-CoA mutase; Catalyzes the interconversion of succinyl-CoA and methylmalonyl-CoA. Could be part of a pathway that converts succinate to propionate
3-phenylpropionate-dihydrodiol/cinnamic acid-dihydrodiol dehydrogenase; Converts 3-phenylpropionate-dihydrodiol (PP-dihydrodiol) and cinnamic acid-dihydrodiol (CI-dihydrodiol) into 3-(2,3- dihydroxylphenyl)propanoic acid (DHPP) and 2,3-dihydroxicinnamic acid (DHCI), respectively; Belongs to the short-chain dehydrogenases/reductases (SDR) family
Aminomethyltransferase; The glycine cleavage system catalyzes the degradation of glycine
Uncharacterized HTH-type transcriptional regulator YbiH; Putative transcriptional regulator; Protein involved in transcription repressor activity and transcription
NADPH-dependent ferric-chelate reductase; Plays a role in iron homeostasis under excess nickel conditions; Belongs to the SIP oxidoreductase family
