RecB |
Protein FULL name:
exonuclease V (RecBCD complex), beta subunit [Escherichia coli str. K-12 substr. MG1655].
RecB (Escherichia coli strain K-12 substr. MG1655) is product of expression of recB gene.
RecB is involved in:
HRR in Escherichia coli strain K-12 substr. MG1655
- RecBCD resect DNA in 5' to 3' direction in Escherichia coli strain K-12 substr. MG1655
- RecA joins and starts the filament formation in Escherichia coli strain K-12 substr. MG1655
Keywords:
FUNCTION: Required for efficient DNA repair; it catalyzes the unwinding of double-stranded DNA and the cleavage of single- stranded DNA and it stimulates local genetic recombination. All of these activities require concomitant hydrolysis of ATP.
CATALYTIC ACTIVITY: Exonucleolytic cleavage (in the presence of ATP) in either 5'- to 3'- or 3'- to 5'-direction to yield 5'- phosphooligonucleotides.
SUBUNIT: Consist of three subunits; recB, recC and recD.
SIMILARITY: Belongs to the helicase family. UvrD subfamily.
SIMILARITY: Contains 1 uvrD-like helicase ATP-binding domain.
SIMILARITY: Contains 1 uvrD-like helicase C-terminal domain.
