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

priSDNA primase, putative; Catalytic subunit of DNA primase, an RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication. The small subunit contains the primase catalytic core and has DNA synthesis activity on its own. Binding to the large subunit stabilizes and modulates the activity, increasing the rate of DNA synthesis while decreasing the length of the DNA fragments, and conferring RNA synthesis capability. The DNA polymerase activity may enable DNA primase to also catalyze primer extension after primer synthesis. May [...] (330 aa)    
Predicted Functional Partners:
priL
Conserved hypothetical protein; Regulatory subunit of DNA primase, an RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication. Stabilizes and modulates the activity of the small subunit, increasing the rate of DNA synthesis, and conferring RNA synthesis capability. The DNA polymerase activity may enable DNA primase to also catalyze primer extension after primer synthesis. May also play a role in DNA repair. Possesses a template- independent 3'-terminal nucleotidyl transferase activity.

pcnA-2
Proliferating cell nuclear antigen homolog (PCNA) (pcnA-2); One of the sliding clamp subunits that acts as a moving platform for DNA processing. Responsible for tethering the catalytic subunit of DNA polymerase to DNA during high-speed replication. Heterotrimer stimulates the Holliday junction resolvase Hjc. DNA polymerase I, DNA ligase and the flap endonuclease may be constitutively associated with the PCNA heterotrimer forming a scanning complex able to couple DNA synthesis and Okazaki fragment maturation.

PriX
Conserved hypothetical protein.
    
 
 0.984
dnaG
Bacterial-like DNA primase (dnaG); RNA polymerase that catalyzes the synthesis of short RNA molecules used as primers for DNA polymerase during DNA replication. Can use NTPs but not dNTPs. Binds DNA. Also part of the exosome, which is a complex involved in RNA degradation. Acts as a poly(A)-binding protein that enhances the interaction between heteropolymeric, adenine- rich transcripts and the exosome. Belongs to the archaeal DnaG primase family.

dpo3
DNA polymerase III (DNA polymerase B3) (pfu polymerase). (dpo3); Replication and Repair.
   
 0.963
dpo1
DNA polymerase I (DNA polymerase B1) (dpo1); This polymerase possesses two enzymatic activities: DNA synthesis (polymerase) and an exonucleolytic activity that degrades single-stranded DNA in the 3'- to 5'-direction. DNA polymerase I, DNA ligase and the flap endonuclease may be constitutively associated with the PCNA heterotrimer forming a scanning complex able to couple DNA synthesis and Okazaki fragment maturation.
  
 0.962
MCM
Minichromosome maintenance protein MCM; Presumptive replicative helicase. Has ATPase and DNA helicase activities. The latter preferentially melts 5'-tailed oligonucleotides and is stimulated by the SSB protein (single-stranded DNA binding protein). The active ATPase sites in the MCM ring are formed through the interaction surfaces of two neighboring subunits such that a critical structure of a conserved arginine finger motif is provided in trans relative to the ATP-binding site of the Walker A box of the adjacent subunit. The helicase function is proposed to use a partially sequential [...]

rnhB
Ribonuclease HII (rnhB); Endonuclease that specifically degrades the RNA of RNA-DNA hybrids; Belongs to the RNase HII family.
  
  
 0.961
rfc
Activator 1, replication factor C, small subunit (rfc); Part of the RFC clamp loader complex which loads the PCNA sliding clamp onto DNA. The complex possesses DNA-dependent ATPase activity; Belongs to the activator 1 small subunits family. RfcS subfamily.

nop10
Conserved hypothetical protein; Involved in ribosome biogenesis; more specifically in 18S rRNA pseudouridylation and in cleavage of pre-rRNA.
