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

nrdRProbable transcriptional regulatory protein NrdR; Negatively regulates transcription of bacterial ribonucleotide reductase nrd genes and operons by binding to NrdR- boxes; Belongs to the NrdR family. (154 aa)    
Predicted Functional Partners:
lexA
Repressor LexA; Represses a number of genes involved in the response to DNA damage (SOS response), including recA and lexA. Has been shown to bind to the 14 bp palindromic sequence 5'-CGAACNNNNGTTCG-3'. In the presence of single-stranded DNA, RecA interacts with LexA causing an autocatalytic cleavage which disrupts the DNA-binding part of LexA, leading to derepression of the SOS regulon and eventually DNA repair.

cobN
Rv2062c, (MTCY49.01c, MTV019.03), len: 1194 aa. cobN, cobalamin biosynthesis protein, similar to many.
      
 0.778
chiZ
Possible conserved membrane protein; Cell wall hydrolase that modulates cell division process. Probably acts by modulating FtsZ ring assembly. Murein hydrolase activity is targeted to sites of nascent peptidoglycan (PG) synthesis. Overproduction compromises midcell localization of FtsZ rings, but has no effect on the intracellular levels of FtsZ.

recD
RecBCD enzyme subunit RecD; A helicase/nuclease that prepares dsDNA breaks (DSB) for recombinational DNA repair. Binds to DSBs and unwinds DNA via a highly rapid and processive ATP-dependent bidirectional helicase activity. Unwinds dsDNA until it encounters a Chi (crossover hotspot instigator) sequence from the 3' direction. Cuts ssDNA a few nucleotides 3' to the Chi site. The properties and activities of the enzyme are changed at Chi. The Chi-altered holoenzyme produces a long 3'-ssDNA overhang and facilitates RecA-binding to the ssDNA for homologous DNA recombination and repair. Holo [...]

ribG
Diaminohydroxyphosphoribosylaminopyrimidine deaminase; Converts 2,5-diamino-6-(ribosylamino)-4(3h)-pyrimidinone 5'- phosphate into 5-amino-6-(ribosylamino)-2,4(1h,3h)-pyrimidinedione 5'- phosphate; In the C-terminal section; belongs to the HTP reductase family.

Rv2717c
Conserved protein; May play a role in the intracellular transport of hydrophobic ligands.
  
    0.724
Rv3242c
Conserved hypothetical protein; Rv3242c, (MTCY20B11.17c), len: 213 aa. Conserved hypothetical protein, highly similar in N-terminus to Q9CCI9|ML0776 hypothetical protein from Mycobacterium leprae (85 aa), FASTA scores: opt: 324, E(): 1.7e-13,(78.1% identity in 64 aa overlap). Also similar to Q9RUJ7|DR1389 putative competence protein COMF from Deinococcus radiodurans (219 aa), FASTA scores: opt: 223,E(): 6.3e-07, (35.8% identity in 215 aa overlap); BAB50338|MLL3453 hypothetical protein from Rhizobium loti (Mesorhizobium loti) (240 aa), FASTA scores: opt: 218, E(): 1.4e-06, (28.5% identi [...]

nrdF2
Ribonucleoside-diphosphate reductase subunit beta nrdF2; Provides the precursors necessary for DNA synthesis. Catalyzes the biosynthesis of deoxyribonucleotides from the corresponding ribonucleotides. Two genes for this protein are present in M.tuberculosis; this is the active form. When coexpressed in E.coli with nrdE the 2 proteins complement a temperature-sensitive E.coli mutant; Belongs to the ribonucleoside diphosphate reductase small chain family.

Rv1556
Rv1556, (MTCY48.09c), len: 202 aa. Possible regulatory protein, similar to X86780|SHGCPIR2|g987088 orfY, regulator of antibiotic transport complexes from Streptomyces hygroscopicus (204 aa), FASTA score: opt: 251,E(): 1.7e-10, (33.8% identity in 201 aa overlap) and others.

cobL
Precorrin-6Y C(5,15)-methyltransferase (decarboxylating) CobL; Catalyzes the methylation of both C-5 and C-15 in precorrin- 6Y to form precorrin-8X.
