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

miaAtRNA dimethylallyltransferase; Catalyzes the transfer of a dimethylallyl group onto the adenine at position 37 in tRNAs that read codons beginning with uridine, leading to the formation of N6-(dimethylallyl)adenosine (i(6)A). (314 aa)    
Predicted Functional Partners:
log
Conserved hypothetical protein; Catalyzes the hydrolytic removal of ribose 5'-monophosphate from nitrogen N6-modified adenosines, the final step of bioactive cytokinin synthesis. Is involved in the synthesis of isopentenyladenine (iP) and 2-methylthio-iP (2MeS-iP), the most abundant cytokinins detected in M.tuberculosis lysates and supernatants. Is also able to convert trans-zeatin-riboside monophosphate (tZRMP) to trans-zeatin (tZ) in vitro; however, it may not be involved in the biosynthesis of this minor cytokinin in vivo. Accumulation of Rv1205 sensitizes M.tuberculosis to nitric o [...]

miaB
Conserved hypothetical alanine, arginine-rich protein; Catalyzes the methylthiolation of N6-(dimethylallyl)adenosine (i(6)A), leading to the formation of 2-methylthio-N6- (dimethylallyl)adenosine (ms(2)i(6)A) at position 37 in tRNAs that read codons beginning with uridine.
  
 0.939
hflX
Probable GTP-binding protein HflX; GTPase that associates with the 50S ribosomal subunit and may have a role during protein synthesis or ribosome biogenesis. Belongs to the TRAFAC class OBG-HflX-like GTPase superfamily. HflX GTPase family.

Rv2728c
Rv2728c, (MTCY154.08c), len: 231 aa. Conserved ala-rich protein, equivalent to Q49835|ML0994|B2235_C1_162 hypothetical protein from Mycobacterium leprae (232 aa),FASTA scores: opt: 1037, E(): 1.2e-54, (68.55% identity in 232 aa overlap). Also similar to O69964|SC4H2.09 from Streptomyces coelicolor (237 aa), FASTA scores: opt: 300,E(): 7.7e-11, (32.8% identity in 241 aa overlap); and some similarity with other proteins e.g. Q14234|ELN elastin from Homo sapiens (Human) (757 aa), FASTA scores: opt: 161, E(): 0.03, (30.6% identity in 242 aa overlap); P55488|Y4IE hypothetical 15.4 KDA prote [...]

dapF
Probable diaminopimelate epimerase DapF (DAP epimerase); Catalyzes the stereoinversion of LL-2,6-diaminoheptanedioate (L,L-DAP) to meso-diaminoheptanedioate (meso-DAP), a precursor of L- lysine and an essential component of the bacterial peptidoglycan.
  
    0.850
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.

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).
 
  
 0.691
whiB4
Probable transcriptional regulatory protein WhiB-like WhiB4; Redox-responsive transcriptional regulator that regulates a set of genes involved in protection against environmental stresses encountered during infection. The loss of the O(2) and NO-responsive 4Fe-4S cluster and subsequent redox modifications of Cys residue thiols (possibly by disulfide bond formation) may activate its role in gene regulation. The thiol-oxidized apo-form binds in a sequence non- specific manner to GC-rich DNA, probably in the minor groove. Represses transcription of a number of genes including itself. The [...]

rsmH
Conserved protein; Specifically methylates the N4 position of cytidine in position 1402 (C1402) of 16S rRNA; Belongs to the methyltransferase superfamily. RsmH family.
 
 
 0.656
pafA
Proteasome accessory factor a PafA; Catalyzes the covalent attachment of the prokaryotic ubiquitin-like protein modifier Pup to the proteasomal substrate proteins, thereby targeting them for proteasomal degradation. This tagging system is termed pupylation. The ligation reaction involves the side-chain carboxylate of the C-terminal glutamate of Pup and the side- chain amino group of a substrate lysine. PafA is required to confer resistance against the lethal effects of reactive nitrogen intermediates (RNI), antimicrobial molecules produced by activated macrophages and other cell types.
