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

dnaAChromosomal replication initiator protein DnaA; Plays an important role in the initiation and regulation of chromosomal replication. Binds to the origin of replication; it binds specifically double-stranded DNA at a 9 bp consensus (dnaA box): 5'- TTATC[CA]A[CA]A-3'. DnaA binds to ATP and to acidic phospholipids (By similarity). Binds its own promoter. (507 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 [...]

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.
  
 
 0.959
recF
DNA replication and repair protein RecF (single-strand DNA binding protein); The RecF protein is involved in DNA metabolism; it is required for DNA replication and normal SOS inducibility. RecF binds preferentially to single-stranded, linear DNA. It also seems to bind ATP (By similarity).

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).

rpmH
Rv3924c, (MTV028.15), len: 47 aa. rpmH, 50s ribosomal protein l34 (see citations below), equivalent to many mycobacterial 50S ribosomal protein L34 e.g. P46386|RL34_MYCLE|RPMH|ML2713 from Mycobacterium leprae (47 aa), FASTA scores: opt: 287, E(): 8.5e-17, (91.5% identity in 47 aa overlap); and Q9L7L8|RL34_MYCPA|RPMH from Mycobacterium paratuberculosis (47 aa), FASTA scores: opt: 281, E(): 2.6e-16, (89.35% identity in 47 aa overlap). Also highly similar to other ribosomal proteins e.g. P27901|RL34_STRCO|RPMH|STH24.02 from Streptomyces coelicolor (45 aa), FASTA scores: opt: 234, E(): 1.4 [...]

ftsZ
Cell division protein FtsZ; Essential cell division protein that forms a contractile ring structure (Z ring) at the future cell division site. The regulation of the ring assembly controls the timing and the location of cell division. One of the functions of the FtsZ ring is to recruit other cell division proteins to the septum to produce a new cell wall between the dividing cells. Binds GTP and shows GTPase activity.

gyrB
DNA gyrase subunit B; A type II topoisomerase that negatively supercoils closed circular double-stranded (ds) DNA in an ATP-dependent manner to maintain chromosomes in an underwound state, while in the absence of ATP it relaxes supercoiled dsDNA. . Also catalyzes the interconversion of other topological isomers of dsDNA rings, including catenanes. Gyrase from M.tuberculosis has higher decatenation than supercoiling activity compared to E.coli; as M.tuberculosis only has 1 type II topoisomerase, gyrase has to fulfill the decatenation function of topoisomerase IV as well. At comparable c [...]
 
  
 0.841
rnpA
Ribonuclease P protein component RnpA (RNaseP protein) (RNase P protein) (protein C5); RNaseP catalyzes the removal of the 5'-leader sequence from pre-tRNA to produce the mature 5'-terminus. It can also cleave other RNA substrates such as 4.5S RNA. The protein component plays an auxiliary but essential role in vivo by binding to the 5'-leader sequence and broadening the substrate specificity of the ribozyme. Belongs to the RnpA family.
  
  
 0.834
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.
