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

dnaE1Probable DNA polymerase III (alpha chain) DnaE1 (DNA nucleotidyltransferase); DNA polymerase III is a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria. This DNA polymerase also exhibits 3' to 5' exonuclease activity. The alpha chain is the DNA polymerase (By similarity); Belongs to the DNA polymerase type-C family. DnaE subfamily. (1184 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 [...]

Rv2413c
Rv2413c, (MTCY253.07), len: 316 aa. Conserved hypothetical protein, highly similar to O33133|MLCL536.07c|ML0603|Q49756|G466975|B1937_F2_36 hypothetical 39.1 KDA protein from Mycobacterium leprae (389 aa), FASTA scores: opt: 1683, E(): 1.8e-88, (83.9% identity in 316 aa overlap). ML0603 is a putative lipoprotein with an N-terminal signal sequence and appropriately positioned prokaryotic lipoprotein lipid attachment site that is not present in Rv2413c as this seems to be 73 aa shorter. Also some similarity with various proteins from other organisms e.g. Q9RDM2|SCC123.02c putative DNA-bin [...]

Rv3644c
Possible DNA polymerase; Rv3644c, (MTCY15C10.08), len: 401 aa. Possible DNA polymerase, equivalent to O69546|MLCB2548.29c|ML0202 hypothetical 42.7 KDA protein from Mycobacterium leprae (405 aa), FASTA scores: opt: 2180, E(): 6.1e-116, (84.4% identity in 404 aa overlap). Similar (in totality or in first 200 aa) to DNA polymerases III, delta' or gamma subunit, e.g. Q9X906|SCH5.03c putative DNA polymerase from Streptomyces coelicolor (401 aa), FASTA scores: opt: 1022,E(): 1.5e-50, (47.05% identity in 404 aa overlap); Q9RRS5|DR2410 DNA polymerase III, tau/gamma subunit from Deinococcus rad [...]

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.
