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

Score
aspCRv0337c, (MTCY279.04c), len: 429 aa. Probable aspC,aspartate aminotransferase (transaminase A), equivalent to CAC32019.1|AL583925 probable aspartate aminotransferase from Mycobacterium leprae (437 aa). Also highly similar to many e.g. Q48143|U32823 aspartate aminotransferase (404 aa), FASTA scores: opt: 1646, E(): 0, (57.2% identity in 404 aa overlap). Also some similarity to Rv3565|MTCY06G11.12 from Mycobacterium tuberculosis FASTA score: (27.2% identity in 383 aa overlap). Belongs to class-I of pyridoxal-phosphate-dependent aminotransferases. Cofactor: pyridoxal phosphate. (429 aa)    
Predicted Functional Partners:
gdh
Probable NAD-dependent glutamate dehydrogenase Gdh (NAD-Gdh) (NAD-dependent glutamic dehydrogenase); Catalyzes the reversible conversion of L-glutamate to 2- oxoglutarate.

ilvD
Rv0189c, (MTCI28.28c), len: 575 aa. Probable ilvD,dihydroxy-acid dehydratase, similar to many e.g. ILVD_LACLA|Q02139 dihydroxy-acid dehydratase (dad) from Lactococcus lactis (subsp. lactis) (Streptococcus lactis) (570 aa), FASTA scores: opt: 1605, E(): 0, (46.0% identity in 561 aa overlap). Also similar to ML2608|MLCL622.06c|O06069|ILVD_MYCLE dihydroxy-acid dehydratase from Mycobacterium leprae (564 aa). Contains PS00886 Dihydroxy-acid and 6-phosphogluconate dehydratases signature 1. Belongs to the ILVD / EDD family. Cofactor: binds 1 4FE-4S cluster (potential).
  
 
 0.927
ald
Secreted L-alanine dehydrogenase Ald (40 kDa antigen) (TB43); Catalyzes the reversible reductive amination of pyruvate to L-alanine. However, since the physiological environment of M.tuberculosis has a neutral pH, it can be assumed that the enzyme catalyzes exclusively the formation of L-alanine. May play a role in cell wall synthesis as L-alanine is an important constituent of the peptidoglycan layer; Belongs to the AlaDH/PNT family.
   
 
 0.927
leuA
2-isopropylmalate synthase LeuA (alpha-isopropylmalate synthase) (alpha-IPM synthetase) (IPMS); Catalyzes the condensation of the acetyl group of acetyl-CoA with 3-methyl-2-oxobutanoate (2-oxoisovalerate) to form 3-carboxy-3- hydroxy-4-methylpentanoate (2-isopropylmalate).
  
 
 0.914
argJ
Probable glutamate N-acetyltransferase ArgJ; Catalyzes two activities which are involved in the cyclic version of arginine biosynthesis: the synthesis of N-acetylglutamate from glutamate and acetyl-CoA as the acetyl donor, and of ornithine by transacetylation between N(2)-acetylornithine and glutamate.
  
 
 0.913
ilvE
Branched-chain amino acid transaminase IlvE; Catalyzes the reversible transfers of an amino group from glutamate to the alpha-ketoacid of the respective amino acid in the final step in the biosynthesis of branchedchain amino acids. The amino acids can be ranked in the following order with respect to their efficiency as amino donor: Leu > Ile > Val. Belongs to the class-IV pyridoxal-phosphate-dependent aminotransferase family.
  
 
 0.911
argA
Probable L-glutamate alpha-N-acetyltranferase ArgA (alpha-N-acetylglutamate synthase); Catalyzes the conversion of L-glutamate to alpha-N-acetyl-L- glutamate. L-glutamine is a significantly better substrate compared to L-glutamate; Belongs to the acetyltransferase family.
  
 
 0.906
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.
  
 
 0.905
alr
Alanine racemase Alr; Catalyzes the interconversion of L-alanine and D-alanine. D- alanine plays a key role in peptidoglycan cross-linking.
  
 
 0.865
icd1
Isocitrate dehydrogenase [NADP]; Rv3339c, (MTV016.39c), len: 409 aa. Probable icd1,isocitrate dehydrogenase NADP-dependent, highly similar to many e.g. Q9A5C8|CC2522 from Caulobacter crescentus (403 aa), FASTA scores: opt: 1972, E(): 4.6e-115, (72.45% identity in 403 aa overlap); AAF73472|ICD from Rhizobium meliloti (404 aa), FASTA scores: opt: 1968, E(): 8.1e-115,(73.2% identity in 403 aa overlap); P50215|IDH_SPHYA from Sphingomonas yanoikuyae (406 aa), FASTA scores: opt: 1964,E(): 1.4e-114, (71.45% identity in 403 aa overlap); etc. Contains PS00470 Isocitrate and isopropylmalate dehy [...]
