"recA" - Recombinase A in Synechocystis sp. PCC6803
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:
some 3D structure is known or predicted
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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
protein homology
Your Input:
Gene Fusion
recARecombinase 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 (354 aa)    
Predicted Functional Partners:
UmuC protein (116 aa)
DNA polymerase I; In addition to polymerase activity, this DNA polymerase exhibits 3’ to 5’ and 5’ to 3’ exonuclease activity (986 aa)
SOS function regulatory protein LexA; A probable transcription regulator, probably involved in carbon metabolism (PubMed-15225304). Binds and probably regulates expression of bidirectional hydrogenase (hoxEFUHY), probably activates its transcription (PubMed-16102913, PubMed-16238629). A possible regulator of redox-responsive genes. Binds 2 direct repeats of the DNA with sequence 5’-CTA-N(9)-CTA-3’ in the upstream region of both its own gene (includes the transcription start site) and crhR (includes the initiation codon) in a sequence-specific manner; does not bind crhR RNA (PubMed-1855 [...] (203 aa)
ATP-dependent DNA helicase RecQ; DNA helicase (478 aa)
Hypothetical protein; SbcCD cleaves DNA hairpin structures. These structures can inhibit DNA replication and are intermediates in certain DNA recombination reactions. The complex acts as a 3’->5’ double strand exonuclease that can open hairpins. It also has a 5’ single-strand endonuclease activity (416 aa)
DNA mismatch repair protein; This protein is involved in the repair of mismatches in DNA. It is required for dam-dependent methyl-directed DNA mismatch repair. May act as a "molecular matchmaker", a protein that promotes the formation of a stable complex between two or more DNA-binding proteins in an ATP-dependent manner without itself being part of a final effector complex (By similarity) (563 aa)
DNA helicase II (793 aa)
Holliday junction DNA helicase; The RuvA-RuvB complex in the presence of ATP renatures cruciform structure in supercoiled DNA with palindromic sequence, indicating that it may promote strand exchange reactions in homologous recombination. RuvAB is a helicase that mediates the Holliday junction migration by localized denaturation and reannealing (361 aa)
DNA recombinase; Critical role in recombination and DNA repair. Helps process Holliday junction intermediates to mature products by catalyzing branch migration. Has a DNA unwinding activity characteristic of a DNA helicase with a 3’- to 5’- polarity. Unwinds branched duplex DNA (Y-DNA) (By similarity) (831 aa)
DNA polymerase III beta subunit; DNA polymerase III is a complex, multichain enzyme responsible for most of the replicative synthesis in bacteria. This DNA polymerase also exhibits 3’ to 5’ exonuclease activity. The beta chain is required for initiation of replication once it is clamped onto DNA, it slides freely (bidirectional and ATP- independent) along duplex DNA (By similarity) (391 aa)
