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

PE_PGRS35PE-PGRS family protein PE_PGRS35; Rv1983, (MTCY39.36c), len: 558 aa. PE_PGRS35, Member of the Mycobacterium tuberculosis PE family, PGRS subfamily of gly-rich proteins (see Brennan & Delogu 2002). Similar to other PE proteins e.g. Rv0977, etc. Contains PS00141 Eukaryotic and viral aspartyl proteases active site. (558 aa)    
Predicted Functional Partners:
vapC36
Possible toxin VapC36. Contains PIN domain; Toxic component of a type II toxin-antitoxin (TA) system. An RNase. Its cognate antitoxin is VapB36 (By similarity). Belongs to the PINc/VapC protein family.
     
 0.637
vapB36
Possible antitoxin VapB36; Possibly the antitoxin component of a type II toxin-antitoxin (TA) system. Its cognate toxin is VapC36.
       0.535
Rv1987
Possible chitinase; Rv1987, (MTCY39.32c), len: 142 aa. Possible chitinase, similar to several e.g. P36909|CHIT_STRLI chitinase c precursor (619 aa) FASTA scores, opt: 324, E(): 1.2e-14, (39.5% identity in 129 aa overlap).
      
 0.510
nrdF1
Ribonucleoside-diphosphate reductase subunit beta nrdF1; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides (By similarity). Two genes for this protein are present in M.tuberculosis; this is thought to not be the active form. When coexpressed in E.coli with nrdE the 2 proteins do not complement a temperature-sensitive E.coli mutant, whereas the other gene (nrdF2) does complement; Belongs to the ribonucleoside diphosphate reductase small chain family.
     
 0.493
Rv1978
Conserved protein; Rv1978, (MTV051.16), len: 282 aa. Conserved protein,similar to several hypothetical proteins and methyltransferases e.g. X86780|SHGCPIR.15 methyltransferase from S. hygroscopicus (211 aa), FASTA scores: opt: 151,E(): 0.0072, (30.6% identity in 121 aa overlap).
      
 0.439
erm(37)
Rv1988, (MTCY39.31c), len: 179 aa. Probable erm(37),23S rRNA methyltransferase, similar to ERME_SACER|P07287 rrna adenine n-6-methyltransferase (370 aa), FASTA scores: opt: 259, E(): 2e-11, (35.1% identity in 171 aa overlap); contains PS00092 N-6 Adenine-specific DNA methylases signature. Also similar to Mycobacterium tuberculosis Rv1010 ksgA 16S rRNA dimethyltransferase. This region is a possible MT-complex-specific genomic island (See Becq et al., 2007); Belongs to the class I-like SAM-binding methyltransferase superfamily. rRNA adenine N(6)-methyltransferase family.
     
 0.438
Rv1979c
Possible conserved permease; Probable amino-acid or metabolite transport protein. Belongs to the amino acid-polyamine-organocation (APC) superfamily.
