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

polAProbable 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. (904 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 [...]

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).
  
 0.995
Rv1277
Rv1277, (MTCY50.05c), len: 417 aa. Conserved hypothetical protein, some similarity to 3914967|O68033|SBCD_RHOCA exonuclease SBCD homolog from Rhodobacter capsulatus (405 aa). May be sbcD protein (see Mizrahi & Andersen 1998).
  
 0.989
Rv2529
Hypothetical protein; Rv2529, (MTCY159.27c), len: 463 aa. Hypothetical unknown protein. Note that C-terminal part is similar to short region of Q53609|MTS1_STRAL|SALIM modification methylase SALI from Streptomyces albus G (587 aa), FASTA scores: opt: 170, E(): 0.016, (59.45% identity in 37 aa overlap).

topA
DNA topoisomerase 1; Releases the supercoiling and torsional tension of DNA, which is introduced during the DNA replication and transcription, by transiently cleaving and rejoining one strand of the DNA duplex. Introduces a single-strand break via transesterification at a target site in duplex DNA. The scissile phosphodiester is attacked by the catalytic tyrosine of the enzyme, resulting in the formation of a DNA-(5'-phosphotyrosyl)-enzyme intermediate and the expulsion of a 3'-OH DNA strand. The free DNA strand then undergoes passage around the unbroken strand, thus removing DNA super [...]

dinG
Probable ATP-dependent helicase DinG; Probable helicase involved in DNA repair and perhaps also replication; Belongs to the helicase family. DinG subfamily.
  
 0.955
Rv1278
Hypothetical protein; Rv1278, (MTCY50.04c), len: 875 aa. Hypothetical unknown protein, possible coiled-coil regions, contains PS00017 ATP/GTP-binding site motif A. A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004).
  
 0.952
ligD
Multifunctional non-homologous end joining DNA repair protein LigD; With Ku forms a non-homologous end joining (NHEJ) repair enzyme which repairs DNA double-strand breaks (DSB) with reduced fidelity. Recognizes, processes and reseals DSBs, including repairs on incompatible DSB which require 3'-resection, gap filling and ligation. Anneals the 3' overhanging strands from opposing breaks to form a gapped intermediate, which then can be extended in trans by using the termini as primers for extension of the annealed break. Binds to the recessed 5'-phosphate moiety of the downstream DNA stra [...]

dnaB
Probable replicative DNA helicase DnaB; Participates in initiation and elongation during chromosome replication; it exhibits DNA-dependent ATPase activity; Belongs to the helicase family. DnaB subfamily.
