CC   -!- FUNCTION: Binds preferentially to single-stranded DNA and therefore,
CC       destabilizes double-stranded DNA. It is involved in DNA replication,
CC       repair and recombination. Binds ss-DNA as the replication fork advances
CC       and stimulates the replisome processivity and accuracy.
CC   -!- SUBUNIT: Homodimer in the absence of DNA, monomer when binding DNA.
CC       {ECO:0000250}.
CC   -!- MISCELLANEOUS: Interacts with the polymerase and the uvsX and uvsY
CC       proteins. {ECO:0000250}.
