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:
some 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

roxA50S ribosomal protein L16 arginine hydroxylase; Growth-regulating oxygenase that catalyzes the hydroxylation of 50S ribosomal protein L16 on 'Arg-81' (373 aa)    
Predicted Functional Partners:
rplP
Large subunit ribosomal protein l16; This protein binds directly to 23S ribosomal RNA and is located at the A site of the peptidyltransferase center. It contacts the A and P site tRNAs . It has an essential role in subunit assembly, which is not well understood

dsbB
Oxidoreductase that catalyzes reoxidation of dsba protein disulfide isomerase i; Required for disulfide bond formation in some periplasmic proteins such as PhoA or OmpA. Acts by oxidizing the DsbA protein. PhoP-regulated transcription is redox-sensitive, being activated when the periplasm becomes more reducing (deletion of dsbA/dsbB, treatment with dithiothreitol). MgrB acts between DsbA/DsbB and PhoP/PhoQ in this pathway

hflD
High frequency lysogenization protein; Negative regulator of phage lambda lysogenization. Contributes to the degradation of the phage regulatory protein CII. Acts probably by holding CII on the membrane surface, away from the target promoters, but close to the FtsH protease
  
  
 0.829
tfaE
E14 prophage; putative tail fiber assembly protein TfaE; Prophage tail fiber assembly protein homolog TfaE; Phage or Prophage Related

mnmA
Trna(gln,lys,glu) u34 2-thiouridylase; Catalyzes the 2-thiolation of uridine at the wobble position (U34) of tRNA(Lys), tRNA(Glu) and tRNA(Gln), leading to the formation of s(2)U34, the first step of tRNA-mnm(5)s(2)U34 synthesis. Sulfur is provided by IscS, via a sulfur-relay system. Binds ATP and its substrate tRNAs

ybiX
Fe(ii)-dependent oxygenase superfamily protein; PKHD-type hydroxylase YbiX; Putative enzyme

phoP
Response regulator in two-component regulatory system with phoq; Member of the two-component regulatory system PhoP/PhoQ involved in adaptation to low Mg(2+) environments and the control of acid resistance genes. In low periplasmic Mg(2+), PhoQ phosphorylates PhoP, resulting in the expression of PhoP-activated genes (PAG) and repression of PhoP-repressed genes (PRG). In high periplasmic Mg(2+), PhoQ dephosphorylates phospho-PhoP, resulting in the repression of PAG and may lead to expression of some PRG (By similarity). Mediates magnesium influx to the cytosol by activation of MgtA. Pro [...]

phoQ
Sensory histidine kinase in two-component regulatory system with phop; Member of the two-component regulatory system PhoP/PhoQ involved in adaptation to low Mg(2+) environments and the control of acid resistance genes. In low periplasmic Mg(2+), PhoQ functions as a membrane-associated protein kinase that undergoes autophosphorylation and subsequently transfers the phosphate to PhoP, resulting in the expression of PhoP-activated genes (PAG) and repression of PhoP- repressed genes (PRG). In high periplasmic Mg(2+), acts as a protein phosphatase that dephosphorylates phospho-PhoP, resulti [...]
