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

defProbable polypeptide deformylase Def (PDF) (formylmethionine deformylase); Removes the formyl group from the N-terminal Met of newly synthesized proteins. Requires at least a dipeptide for an efficient rate of reaction. N-terminal L-methionine is a prerequisite for activity but the enzyme has broad specificity at other positions (By similarity); Belongs to the polypeptide deformylase family. (197 aa)    
Predicted Functional Partners:
Rv0428c
GCN5-related N-acetyltransferase; Rv0428c, (MTCY22G10.25c), len: 302 aa. Probable acetyltransferase. Contains GNAT (Gcn5-related N-acetyltransferase) domain in C-terminal part. See Vetting et al. 2005.

xthA
Probable exodeoxyribonuclease III protein XthA (exonuclease III) (EXO III) (AP endonuclease VI); Rv0427c, (MTCY22G10.24c), len: 291 aa. Probable xthA (alternate gene name: xth), exodeoxyribonuclease III protein (see citation below), similar to others e.g. EX3_ECOLI|P09030 exodeoxyribonuclease III from Escherichia Coli strain K12 (268 aa), FASTA scores: opt: 360, E(): 1.2e-17, (29.3% identity in 270 aa overlap); etc. Belongs to the AP/EXOA family of DNA repair enzymes.
  
  
 0.952
mapB
Methionine aminopeptidase MapB (map) (peptidase M); Removes the N-terminal methionine from nascent proteins. The N-terminal methionine is often cleaved when the second residue in the primary sequence is small and uncharged (Met-Ala-, Cys, Gly, Pro, Ser, Thr, or Val). Requires deformylation of the N(alpha)-formylated initiator methionine before it can be hydrolyzed.
 
 
 0.947
tig
Probable trigger factor (TF) protein Tig; Involved in protein export. Acts as a chaperone by maintaining the newly synthesized protein in an open conformation. Functions as a peptidyl-prolyl cis-trans isomerase (By similarity). Belongs to the FKBP-type PPIase family. Tig subfamily.
 
 
 0.934
rplU
50S ribosomal protein L21 RplU; This protein binds to 23S rRNA in the presence of protein L20; Belongs to the bacterial ribosomal protein bL21 family.
 
 
 0.927
fmt
Probable methionyl-tRNA formyltransferase Fmt; Attaches a formyl group to the free amino group of methionyl- tRNA(fMet). The formyl group appears to play a dual role in the initiator identity of N-formylmethionyl-tRNA by promoting its recognition by IF2 and preventing the misappropriation of this tRNA by the elongation apparatus; Belongs to the Fmt family.
 
 
 0.926
rplV
50S ribosomal protein L22 RplV; This protein binds specifically to 23S rRNA; its binding is stimulated by other ribosomal proteins, e.g. L4, L17, and L20. It is important during the early stages of 50S assembly. It makes multiple contacts with different domains of the 23S rRNA in the assembled 50S subunit and ribosome (By similarity).
   
 
 0.924
rpsT
30S ribosomal protein S20 RpsT; Binds directly to 16S ribosomal RNA; Belongs to the bacterial ribosomal protein bS20 family.
  
 
 0.924
rplI
50S ribosomal protein L9 RplI; Binds to the 23S rRNA.

rplQ
Rv3456c, (MTCY13E12.09c), len: 180 aa. rplQ, 50S ribosomal protein L17, equivalent to Q9X797|RL17_MYCLE|ML1956|MLCB1222.26c 50S ribosomal protein L17 from Mycobacterium leprae (170 aa), FASTA scores: opt: 874, E(): 9.5e-45, (81.85% identity in 171 aa overlap). Also highly similar to other e.g. O86775|RL17_STRCO|SC6G4.08 from Streptomyces coelicolor (168 aa), FASTA scores: opt: 609, E(): 3.7e-29, (60.0% identity in 170 aa overlap); BAB47931|MLR0326 from Rhizobium loti (Mesorhizobium loti) (143 aa), FASTA scores: opt: 404, E(): 3.7e-17, (49.65% identity in 139 aa overlap); Q9Z9H5|RL17_TH [...]
