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

pcnAPoly(A) polymerase PcnA; Rv3907c, (MTCY15F10.04), len: 480 aa. Probable pcnA,polynucleotide polymerase, equivalent to Q9CCY1|PCNA|ML2697 PCNA protein from Mycobacterium leprae (486 aa), FASTA scores: opt: 2713, E(): 4.3e-160, (84.1% identity in 478 aa overlap); and Q59534|PCNB POLYA polymerase from Mycobacterium leprae (411 aa) FASTA scores: opt: 2077, E(): 7.1e-121, (82.55% identity in 373 aa overlap). Also highly similar to many e.g. Q9X8T2|SCH24.18 putative RNA nucleotidyltransferase from Streptomyces coelicolor (483 aa), FASTA scores: opt: 1856, E(): 3.7e-107, (61.55% identity in 4 [...] (480 aa)    
Predicted Functional Partners:
Rv3906c
Rv3906c, (MTCY15F10.05), len: 169 aa. Conserved hypothetical protein, strongly related to Q50578|AT9S (sod related in Escherichia coli) from Mycobacterium tuberculosis strain aoyama B (155 aa), but apparently different as flanking sequences differ and shorter 43 aa,FASTA scores: opt: 548, E(): 1.3e-26, (79.4% identity in 102 aa overlap). Selfmarch results suggest that Rv3906c is not related to any other hypothetical protein from Mycobacterium tuberculosis strain H37Rv except itself. Shows also similarity with Q9VFR2|CG9297 hypothetical protein from Drosophila melanogaster (Fruit fly) ( [...]

gpsI
Polyribonucleotide nucleotidyltransferase; Involved in mRNA degradation. Catalyzes the phosphorolysis of single-stranded polyribonucleotides processively in the 3'- to 5'- direction.
 
 
 0.826
dapB
Dihydrodipicolinate reductase DapB (DHPR); Catalyzes the conversion of 4-hydroxy-tetrahydrodipicolinate (HTPA) to tetrahydrodipicolinate (Probable). Can use both NADH and NADPH as a reductant, with NADH being 6-fold as effective as NADPH.

orn
Oligoribonuclease Orn; 3'-to-5' exoribonuclease specific for small oligoribonucleotides; Belongs to the oligoribonuclease family.
 
  
 0.736
rphA
Probable ribonuclease RphA (RNase PH) (tRNA nucleotidyltransferase); Phosphorolytic 3'-5' exoribonuclease that plays an important role in tRNA 3'-end maturation. Removes nucleotide residues following the 3'-CCA terminus of tRNAs; can also add nucleotides to the ends of RNA molecules by using nucleoside diphosphates as substrates, but this may not be physiologically important. Probably plays a role in initiation of 16S rRNA degradation (leading to ribosome degradation) during starvation.
   
  
 0.696
mutT4
Possible mutator protein MutT4; May be involved in the GO system responsible for removing an oxidatively damaged form of guanine (7,8-dihydro-8-oxoguanine, 8-oxo- dGTP) from DNA and the nucleotide pool (By similarity). In vitro has dATPase rather than 8-oxo-dGTPase activity.

Rv3909
Conserved protein; Rv3909, (MTCY15F10.02c), len: 802 aa. Conserved protein, equivalent to Q9CCY0|ML2699 putative secreted protein from Mycobacterium leprae (797 aa) FASTA scores: opt: 3777, E(): 8.8e-206, (72.35% identity in 803 aa overlap). Note that the N-terminal end is highly similar to Q50196|L222-ORF7 (286 aa), FASTA scores: opt: 1213, E(): 2.7e-61, (71.75% identity in 255 aa overlap); and the C-terminal end is highly similar to Q50197|L222-ORF8 also from Mycobacterium leprae (512 aa) FASTA scores: opt: 2375,E(): 9.9e-127, (71.8% identity in 518 aa overlap). Shows some similarity [...]

mviN
Probable conserved transmembrane protein; Essential for cell growth and peptidoglycan synthesis. In the N-terminal section; belongs to the MurJ/MviN family.

Rv1685c
Rv1685c, (MTCI125.07c), len: 207 aa. Conserved hypothetical protein, some similarity to other Mycobacterium tuberculosis hypothetical regulatory proteins e.g. Q10774|Rv1556|YF56_MYCTU (202 aa), FASTA scores: opt: 111, E(): 1.7e-05, (24.1% identity in 195 aa overlap); and P95215|Rv0258c|MTCY06A4.02c (151 aa) FASTA scores: (32.9% identity in 140 aa overlap); also similar to Q9X8G9|SCE7.13C|AL049819 putative Streptomyces coelicolor transcriptional regulator (204 aa), FASTA scores: opt: 480,E(): 6.4e-25, (40.4% identity in 203 aa overlap).

mazF6
Toxin MazF6; Toxic component of a type II toxin-antitoxin (TA) system. Upon expression in E.coli and in M.smegmatis partially inhibits cell growth and colony formation; its toxic effect is neutralized by coexpression with cognate antitoxin MazE6. Acts as an mRNA interferase on ssRNA, cleaving between the second and third bases in the sequences CUCCU and UUCCU. Further experiments demonstrate that it digests between the first and second bases of UCCUU, yielding a 5'- hydroxyl end; digests M.tuberculosis mRNA (in coding as well as the 5'- and 3'-UTR regions) and 23S rRNA, digests E.coli [...]
