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

ybeXMagnesium and cobalt transporter; Plays a role in the transport of magnesium and cobalt ions (292 aa)    
Predicted Functional Partners:
ybeY
Probable rrna maturation factor; Single strand-specific metallo-endoribonuclease involved in late-stage 70S ribosome quality control and in maturation of the 3' terminus of the 16S rRNA. Acts together with the RNase R to eliminate defective 70S ribosomes, but not properly matured 70S ribosomes or individual subunits, by a process mediated specifically by the 30S ribosomal subunit. Involved in the processing of 16S, 23S and 5S rRNAs, with a particularly strong effect on maturation at both the 5'- and 3'- ends of 16S rRNA as well as maturation of the 5'-end of 23S and 5S rRNAs

ybeZ
Phosphate starvation-inducible protein phoh and related proteins; Belongs to the PhoH family

lnt
Apolipoprotein n-acyltransferase; Catalyzes the phospholipid dependent N-acylation of the N- terminal cysteine of apolipoprotein, the last step in lipoprotein maturation Utilizes a two-step reaction via a ping-pong mechanism . Lnt undergoes covalent modification in the presence of phospholipids, resulting in a thioester acyl-enzyme intermediate. It then transfers the acyl chain to the amine group of the N-terminal diacylglyceryl-modified cysteine of apolipoprotein, leading to the formation of mature triacylated lipoprotein . In vitro, can utilize the phospholipids phosphatidylethanolam [...]

dnaJ
Chaperone hsp40, dnak co-chaperone; Interacts with DnaK and GrpE to disassemble a protein complex at the origins of replication of phage lambda and several plasmids. Participates actively in the response to hyperosmotic and heat shock by preventing the aggregation of stress-denatured proteins and by disaggregating proteins, also in an autonomous, DnaK-independent fashion. Unfolded proteins bind initially to DnaJ; upon interaction with the DnaJ-bound protein, DnaK hydrolyzes its bound ATP, resulting in the formation of a stable complex. GrpE releases ADP from DnaK; ATP binding to DnaK t [...]

gyrB
DNA gyrase negatively supercoils closed circular double- stranded DNA in an ATP-dependent manner to maintain chromosomes in an underwound state This makes better substrates for topoisomerase 4 (ParC and ParE) which is the main enzyme that unlinks newly replicated chromosomes in E.coli . Gyrase catalyzes the interconversion of other topological isomers of double-stranded DNA rings, including catenanes . Relaxes negatively supercoiled DNA in an ATP-independent manner . E.coli gyrase has higher supercoiling activity than other characterized bacterial gyrases; at comparable concentrations [...]

miaB
TRNA-2-methylthio-N6-dimethylallyladenosine synthase; Catalyzes the methylthiolation of N6-(dimethylallyl)adenosine (i(6)A), leading to the formation of 2-methylthio-N6- (dimethylallyl)adenosine (ms(2)i(6)A) at position 37 in tRNAs that read codons beginning with uridine
       0.560
dnaK
Chaperone hsp70, with co-chaperone dnaj; Plays an essential role in the initiation of phage lambda DNA replication, where it acts in an ATP-dependent fashion with the DnaJ protein to release lambda O and P proteins from the preprimosomal complex. DnaK is also involved in chromosomal DNA replication, possibly through an analogous interaction with the DnaA protein. Also participates actively in the response to hyperosmotic shock

gyrA
A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to maintain chromosomes in an underwound state This makes better substrates for topoisomerase IV (ParC and ParE) which is the main enzyme that unlinks newly replicated chromosomes in E.coli . Gyrase catalyzes the interconversion of other topological isomers of dsDNA rings, including catenanes . Relaxes negatively supercoiled DNA in an ATP-independent manner . E.coli gyrase has higher supercoiling activity than many other bacterial gyrases; at comparable concentrations [...]
