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

dinPDNA polymerase IV 2; Poorly processive, error-prone DNA polymerase involved in untargeted mutagenesis. Copies undamaged DNA at stalled replication forks, which arise in vivo from mismatched or misaligned primer ends. These misaligned primers can be extended by PolIV. Exhibits no 3'-5' exonuclease (proofreading) activity. May be involved in translesional synthesis, in conjunction with the beta clamp from PolIII (By similarity). (346 aa)    
Predicted Functional Partners:
dnaN
DNA polymerase III (beta chain) DnaN (DNA nucleotidyltransferase); Confers DNA tethering and processivity to DNA polymerases and other proteins. Acts as a clamp, forming a ring around DNA (a reaction catalyzed by the clamp-loading complex) which diffuses in an ATP- independent manner freely and bidirectionally along dsDNA. Initially characterized for its ability to contact the catalytic subunit of DNA polymerase III (Pol III), a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria; Pol III exhibits 3'-5' exonuclease proofreading activity. The beta ch [...]

Rv3055
Rv3055, (MTCY22D7.26c), len: 204 aa. Possible transcriptional regulatory protein, similar to Q9RD23|SCM1.20c putative TetR-family transcriptional regulator from Streptomyces coelicolor (234 aa), FASTA scores: opt: 471, E(): 4.6e-23, (44.9% identity in 187 aa overlap); and with low similarity to other e.g. Q9ADK8|2SCK31.12 putative TetR-family transcriptional regulator from Streptomyces coelicolor (198 aa), FASTA scores: opt: 208, 2.5e-06, (32.9% identity in 155 aa overlap); Q9ADD9|SCBAC20F6.11c putative TetR-family transcriptional from Streptomyces coelicolor (199 aa),FASTA scores: opt [...]

recA
RecA protein (recombinase A) [contains: endonuclease PI-MTUI (MTU RecA intein)]; Can catalyze the hydrolysis of ATP in the presence of single- stranded DNA, the ATP-dependent uptake of single-stranded DNA by duplex DNA, and the ATP-dependent hybridization of homologous single-stranded DNAs. It interacts with LexA causing its activation and leading to its autocatalytic cleavage.

lppK
Rv2116, (MTCY261.12), len: 189 aa. LppK, conserved lipoprotein, similar to many. Contains N-terminal signal sequence and PS00013 Prokaryotic membrane lipoprotein lipid attachment site. Some similarity to Rv2376c. A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004).

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.

ligC
DNA ligase C; DNA ligase that seals nicks in double-stranded DNA during DNA replication, DNA recombination and DNA repair; Belongs to the ATP-dependent DNA ligase family.
  
 
 0.820
polA
Probable DNA polymerase I PolA; In addition to polymerase activity, this DNA polymerase exhibits 3'-5' and 5'-3' exonuclease activity; Belongs to the DNA polymerase type-A family.

alkA
Probable bifunctional transcriptional activator/DNA repair enzyme AlkA; Is involved in the adaptive response to alkylation damage in DNA caused by alkylating agents. Repairs the Sp diastereomer of DNA methylphosphotriester lesions by a direct and irreversible transfer of the methyl group to one of its own cysteine residues. Also catalyzes the hydrolysis of the deoxyribose N-glycosidic bond to excise 3- methyladenine, 3-methylguanine, 7-methylguanine, O2-methylthymine, and O2-methylcytosine from the damaged DNA polymer formed by alkylation lesions (By similarity); In the C-terminal sect [...]
