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

gcpProbable O-sialoglycoprotein endopeptidase Gcp (glycoprotease); Required for the formation of a threonylcarbamoyl group on adenosine at position 37 (t(6)A37) in tRNAs that read codons beginning with adenine. Is involved in the transfer of the threonylcarbamoyl moiety of threonylcarbamoyl-AMP (TC-AMP) to the N6 group of A37, together with TsaE and TsaB. TsaD likely plays a direct catalytic role in this reaction. (344 aa)    
Predicted Functional Partners:
Rv3421c
Rv3421c, (MTCY78.08), len: 211 aa. Conserved hypothetical protein, equivalent to Q49857|YY21_MYCLE|ML0378|B229_C1_170 hypothetical 38.0 KDA protein from Mycobacterium leprae (359 aa), FASTA scores: opt: 1000, E(): 1.8e-50, (75.6% identity in 205 aa overlap). Also similar to other hypothetical bacterial proteins e.g. O86791|SC6G4.28 from Streptomyces coelicolor (217 aa), FASTA scores: opt: 453, E(): 3.3e-19, (48.1% identity in 212 aa overlap); Q9AC10|CC0059 (glycoprotease family protein) from Caulobacter crescentus (211 aa), FASTA scores: opt: 248, E(): 2e-07, (34.3% identity in 210 aa [...]

tsaE
Conserved hypothetical protein; Required for the formation of a threonylcarbamoyl group on adenosine at position 37 (t(6)A37) in tRNAs that read codons beginning with adenine. Is involved in the transfer of the threonylcarbamoyl moiety of threonylcarbamoyl-AMP (TC-AMP) to the N6 group of A37, together with TsaD and TsaB. TsaE seems to play an indirect role in the t(6)A biosynthesis pathway, possibly in regulating the core enzymatic function of TsaD (By similarity).

rimI
N-alpha-acetyltransferase RimI; N-alpha-acetyltransferase that specifically mediates the acetylation of N-terminal residues. Able to mediate acetylation of a wide variety of N-terminal residues, with preference for hydrophobic N- termini. Acetylates GroS/GroES and GroEL1. Able to acetylate the ribosomal protein S18, but it is unclear whether it acetylates its N- terminal alanine residue; Belongs to the acetyltransferase family. RimI subfamily.

ureG
Urease accessory protein UreG; Facilitates the functional incorporation of the urease nickel metallocenter. This process requires GTP hydrolysis, probably effectuated by UreG.
  
  
 0.931
alr
Alanine racemase Alr; Catalyzes the interconversion of L-alanine and D-alanine. D- alanine plays a key role in peptidoglycan cross-linking.
  
  
 0.916
ksgA
Ribosomal RNA small subunit methyltransferase A; Specifically dimethylates two adjacent adenosines (A1518 and A1519) in the loop of a conserved hairpin near the 3'-end of 16S rRNA in the 30S particle. May play a critical role in biogenesis of 30S subunits.

groES
10 kDa chaperonin GroES (protein CPN10) (protein GroES) (BCG-a heat shock protein) (10 kDa antigen); Binds to Cpn60 in the presence of Mg-ATP and suppresses the ATPase activity of the latter; Belongs to the GroES chaperonin family.

pheT
Rv1650, (MTCY06H11.15), len: 831 aa. Probable pheT,Phenylalanyl-tRNA synthetase beta chain, similar to several e.g. SYFB_ECOLI|P07395 from Escherichia coli (795 aa),FASTA scores: opt: 995, E(): 0, (31.8% identity in 847 aa overlap). Belongs to the phenylalanyl-tRNA synthetase beta chain family - subfamily 1.
  
  
 0.737
pheS
Rv1649, (MTCY06H11.14), len: 341 aa. Probable pheS,Phenylalanyl-tRNA synthetase alpha chain, similar to several e.g. SYFA_ECOLI|P08312 from Escherichia coli (327 aa), FASTA scores: opt: 978, E(): 0, (46.5% identity in 331 aa overlap). Homology suggests this start site, but there is a potential rbs upstream of a gtg 30 bp upstream; contains PS00179 Aminoacyl-transfer RNA synthetases class-II signature 1. Belongs to class-II aminoacyl-tRNA synthetase family. PHE-tRNA synthetase alpha chain subfamily 1.

infB
Probable translation initiation factor if-2 InfB; One of the essential components for the initiation of protein synthesis. Protects formylmethionyl-tRNA from spontaneous hydrolysis and promotes its binding to the 30S ribosomal subunits. Also involved in the hydrolysis of GTP during the formation of the 70S ribosomal complex (By similarity); Belongs to the TRAFAC class translation factor GTPase superfamily. Classic translation factor GTPase family. IF-2 subfamily.
