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

rluD23S rRNA pseudouridine(1911,1915,1917) synthase; Responsible for synthesis of pseudouridine from uracil at positions 1911, 1915 and 1917 in 23S ribosomal RNA. Isomerization occurs as a late step during the assembly of the large ribosomal subunit. (326 aa)    
Predicted Functional Partners:
obgE
GTPase involved in cell partioning and DNA repair; An abundant, essential GTPase which binds GTP, GDP and ppGpp with moderate affinity. Has high guanosine nucleotide exchange rate constants for GTP and GDP, and a relatively low GTP hydrolysis rate stimulated by the 50S ribosomal subunit. It is estimated there are 34000 molecules in log-phase cells and 5600 molecules in stationary- phase cells. Required for chromosome segregation. Plays a role in the stringent response, perhaps by sequestering 50S ribosomal subunits and decreasing protein synthesis , and a non-essential role in the late [...]

yfiH
UPF0124 family protein; Multicopper oxidase with polyphenol oxidase activity. Is able to oxidize syringaldazine and 2,2'-azino-bis(3-ethylbenzthiazoline-6- sulfonic acid) (ABTS) in vitro. The physiological substrate and role of YfiH is not known.

rsfS
Ribosomal silencing factor; Functions as a ribosomal silencing factor. Addition to isolated ribosomal subunits partially inhibits their association, preventing translation. Interacts with ribosomal protein L14 (rplN), blocking formation of intersubunit bridge B8, preventing association of the 30S and 50S ribosomal subunits and the formation of functional ribosomes, thus repressing translation.

yjgA
Ribosome-associated UPF0307 family protein; Putative alpha helix protein; Protein involved in ATP-binding cassette (ABC) transporter activity.
   
 
 0.958
rplU
50S ribosomal subunit protein L21; This protein binds to 23S rRNA in the presence of protein L20.
 
   0.928
rplQ
50S ribosomal subunit protein L17; Requires L15 for assembly into the 50S subunit.
   
 
 0.905
rplM
50S ribosomal subunit protein L13; This protein is one of the early assembly proteins of the 50S ribosomal subunit, although it is not seen to bind rRNA by itself. It is important during the early stages of 50S assembly.
 
   0.898
rplC
50S ribosomal subunit protein L3; One of two assembly initiator proteins, it binds directly near the 3'-end of the 23S rRNA, where it nucleates assembly of the 50S subunit.
 
 
 
 0.894
rplK
50S ribosomal subunit protein L11; Forms part of the ribosomal stalk which helps the ribosome interact with GTP-bound translation factors; Belongs to the universal ribosomal protein uL11 family.
   
 
 0.888
rplO
50S ribosomal subunit protein L15; This protein binds the 5S rRNA. It is required for the late stages of subunit assembly, and is essential for 5S rRNA assembly onto the ribosome; Belongs to the universal ribosomal protein uL15 family.
