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

Rv2228c
Multifunctional protein. Has RNASE H,alpha-ribazole phosphatase, and acid phosphatase activities; Endonuclease that displays both RNase H activity with a hybrid RNA/DNA substrate as well as double-stranded RNase activity. As the only authenticated RNase HI in M.tuberculosis, probably plays an important role in the physiology of this organism, being likely involved in bacterial replication.
  
 
 0.954
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.
 
 
 0.913
rplS
50S ribosomal protein L19 RplS; This protein is located at the 30S-50S ribosomal subunit interface and may play a role in the structure and function of the aminoacyl-tRNA binding site.
 
  
 0.868
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 [...]

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).

coaE
Probable dephospho-CoA kinase CoaE (dephosphocoenzyme a kinase); Catalyzes the phosphorylation of the 3'-hydroxyl group of dephosphocoenzyme A to form coenzyme A. Can also use dATP, with lower efficiency, but cannot use GTP, dGTP or CTP ; In the C-terminal section; belongs to the UPF0157 (GrpB) family.

thyA
Probable thymidylate synthase ThyA (ts) (TSASE); Catalyzes the reductive methylation of 2'-deoxyuridine-5'- monophosphate (dUMP) to 2'-deoxythymidine-5'-monophosphate (dTMP) while utilizing 5,10-methylenetetrahydrofolate (mTHF) as the methyl donor and reductant in the reaction, yielding dihydrofolate (DHF) as a by- product. This enzymatic reaction provides an intracellular de novo source of dTMP, an essential precursor for DNA biosynthesis. Belongs to the thymidylate synthase family. Bacterial-type ThyA subfamily.
