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.

Score
Psyc_2003Possible DNA helicase; Low score to superfamily I DNA and RNA helicases, COG0210. (499 aa)    
Predicted Functional Partners:
recA
Recombinase A; 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; Belongs to the RecA family.
  
 
 0.674
dnaN
DNA polymerase III, beta subunit; 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 chain is required for initiation of [...]

Psyc_0714
Hypothetical protein.
 
     0.655
Psyc_0119
Conserved hypothetical protein.
  
     0.637
topA
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, thus removing DNA supe [...]

Psyc_1611
Possible DNA helicase: AAA ATPase.
 
 
 0.624
polA
DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 5'-3' exonuclease activity; Belongs to the DNA polymerase type-A family.
 
 
 0.621
mutL
DNA mismatch repair protein MutL; The mutL protein binds to mutS, which recognizes and binds to mismatches in DNA duplexes. The mutS-mutL-DNA complex stimulates mutH to cleave the unmethylated DNA strand at the GATC sequence; Contains following domains: DNA mismatch repair protein:ATP-binding region, ATPase-like.
  
 
 0.612
dus
tRNA-U20a,U20b-dihydrouridine synthase; Catalyzes the synthesis of 5,6-dihydrouridine (D), a modified base found in the D-loop of most tRNAs, via the reduction of the C5-C6 double bond in target uridines. Specifically modifies U16 in tRNAs. Belongs to the Dus family. DusC subfamily.
  
 
 0.605
Psyc_0906
Hypothetical protein; Contains an ATP binding domain; Signal predicted by SignalP 2.0 HMM (Signal peptide probabilty 1.000) with cleavage site probability 0.998 at residue 22.
