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

relAPutative GTP pyrophosphokinase; In eubacteria ppGpp (guanosine 3'-diphosphate 5-' diphosphate) is a mediator of the stringent response that coordinates a variety of cellular activities in response to changes in nutritional abundance. This enzyme catalyzes the formation of pppGpp which is then hydrolyzed to form ppGpp (By similarity). (787 aa)    
Predicted Functional Partners:
pykA
Pyruvate kinase; Highly similar to many pyruvate kinases (EC 2.7.1.40) including: Mycobacterium tuberculosis RV1617 SW:KPYK_MYCTU (O06134) (472 aa); Fasta score E(): 0, 90.7% identity in 472 aa overlap and Corynebacterium glutamicum SW:KPYK_CORGL (Q46078) (475 aa); Fasta score E(): 0, 71.8% identity in 468 aa overlap. Contains Pfam match to entry PF00224 PK, Pyruvate kinase. Contains PS00110 Pyruvate kinase active site signature.

gmk
Putative guanylate kinase; Essential for recycling GMP and indirectly, cGMP.
  
 
 0.913
rplF
50S ribosomal protein L6; This protein binds to the 23S rRNA, and is important in its secondary structure. It is located near the subunit interface in the base of the L7/L12 stalk, and near the tRNA binding site of the peptidyltransferase center; Belongs to the universal ribosomal protein uL6 family.

ML0258
Hypothetical protein; Similar to M. tuberculosis Rv1026, hypothetical protein, TR:P96374 (EMBL:AL123456) (319 aa); Fasta score E(): 0, 77.6% identity in 321 aa overlap. Similar to many bacterial hypothetical proteins and shows weak similarity to N-terminal half of Escherichia coli ppx, exopolyphosphatase, SW:PPX_ECOLI (P29014) (512 aa); Fasta score E(): 6.8e-07, 25.3% identity in 297 aa overlap; Shows weak similarity to ML2434.
  
 
 0.909
rplM
50S ribosomal 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.
   
 
 0.909
ndk
Nucleoside diphosphate kinase; Major role in the synthesis of nucleoside triphosphates other than ATP. The ATP gamma phosphate is transferred to the NDP beta phosphate via a ping-pong mechanism, using a phosphorylated active-site intermediate; Belongs to the NDK family.
    
 0.909
ML2434
Conserved hypothetical protein; Degradation of inorganic polyphosphates (polyP). Releases orthophosphate processively from the ends of the polyP chain.
  
 
 0.909
ML0201
Putative membrane protein; Similar to M. tuberculosis Rv3645, probable transmembrane protein, TR:O06362 (EMBL:AL123456) (549 aa); Fasta score E(): 0, 85.3% identity in 530 aa overlap and to several other putative membrane proteins from M. tuberculosis. Shares regions of similarity with adenylate cyclases e.g. Anabaena sp. (strain PCC 7120) cyaA, adenylate cyclase, TR:P94180 (EMBL:D89622) (735 aa); Fasta score E(): 1.5e-16, 33.3% identity in 228 aa overlap. Previously sequenced as TR:O69547 (EMBL:AL023093) (530 aa); Fasta score E(): 0, 99.8% identity in 530 aa overlap. Contains hydropho [...]
