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

PH0622686aa long hypothetical DNA topoisomerase I; 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 [...] (686 aa)

PH1893
361aa long hypothetical protein; Similar to PIR:F64444 percent identity:33.486 in 240aa.
 
 0.914
PH0929
879aa long hypothetical purine NTPase; Part of the Rad50/Mre11 complex, which is involved in the early steps of DNA double-strand break (DSB) repair. The complex may facilitate opening of the processed DNA ends to aid in the recruitment of HerA and NurA. Rad50 controls the balance between DNA end bridging and DNA resection via ATP-dependent structural rearrangements of the Rad50/Mre11 complex; Belongs to the SMC family. RAD50 subfamily.

PH0930
413aa long hypothetical protein; Part of the Rad50/Mre11 complex, which is involved in the early steps of DNA double-strand break (DSB) repair. The complex may facilitate opening of the processed DNA ends to aid in the recruitment of HerA and NurA. Mre11 binds to DSB ends and has both double-stranded 3'-5' exonuclease activity and single-stranded endonuclease activity. Belongs to the MRE11/RAD32 family.

PH0965
967aa long hypothetical leucyl-tRNA synthetase; Similar to PIR:A64379 percent identity: 53.987 in 980aa; owl:F21M12 percent identity: 36.017 in 737aa; Swiss_Prot:Q09996 percent identity: 34.910 in 766aa. motif=aminoacyl-transfer RNA synthetases class-I signature.

PHS055
90aa long hypothetical DNA excision repair protein; Similar to PIR:H64487 percent identity:53.488 in 86aa; GENPEPT:U74491 percent identity:29.577 in 71aa; Swiss_Prot:P07903 percent identity:30.986 in 71aa.

PH1415
343aa long hypothetical 5' nuclease; Structure-specific nuclease with 5'-flap endonuclease and 5'- 3' exonuclease activities involved in DNA replication and repair. During DNA replication, cleaves the 5'-overhanging flap structure that is generated by displacement synthesis when DNA polymerase encounters the 5'-end of a downstream Okazaki fragment. Binds the unpaired 3'-DNA end and kinks the DNA to facilitate 5' cleavage specificity. Cleaves one nucleotide into the double-stranded DNA from the junction in flap DNA, leaving a nick for ligation. Also involved in the base excision repair [...]

PH1637
261aa long hypothetical DNA-directed RNA polymerase subunit D; DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Belongs to the archaeal RpoD/eukaryotic RPB3 RNA polymerase subunit family.

PH1896
650aa long hypothetical ATP-dependent RNA helicase; Similar to PIR:H64487 percent identity: 42.424 in 695aa.
  
 
 0.715
PH1694
445aa long hypothetical signal recognition particle protein; Involved in targeting and insertion of nascent membrane proteins into the cytoplasmic membrane. Binds to the hydrophobic signal sequence of the ribosome-nascent chain (RNC) as it emerges from the ribosomes. The SRP-RNC complex is then targeted to the cytoplasmic membrane where it interacts with the SRP receptor FtsY. Belongs to the GTP-binding SRP family. SRP54 subfamily.
