RecA

An Escherichia coli protein that specifically recognizes single-stranded DNA and anneals it to a complementary sequence in a duplex that is homologous. This results in the displacement of the original complementary strand of the duplex.

plantarum group, a multiplex PCR assay was performed with the recA gene-based primers: paraF (5'-GTCACAGGCATTACGAA AAC-3'), pentF (5'-CAGTGGCGCGGTTGATATC-3'), planF (5'-CCGTTTATGCGGAACACCTA-3'), and pREV (5 '-TCGGGATTACCAAACATCAC-3').
RecA is an ATP-dependent protein able to bind single-stranded DNA (ssDNA) forming a nucleoprotein filament.
When the concentration of this antibiotic decreases, the amount of RecA protein reduces and CheW once again can continue its task of spreading the bacteria.
Genomovar status was determined by amplification of the entire recA gene followed by RFLP (11).

In fiscal year 2001, the number of claims peaked at 3,822--the highest number of claims filed yearly since RECP began in 1992--following the RECA Amendments of 2000 that, among other things, broadened the scope of eligibility for benefits.
A typical Tanoc high-end product is the RecA Jr Digital Video Recorder (DVR), which can record data from up to 16 cameras on a 7X24 basis, with the need for archiving only once every six months.
Biofilms composed of mutant bacteria missing the recA gene showed far less diversity and died rapidly, much as individual colonies did, when exposed to hydrogen peroxide.

RECA determines eligibility by a rather arcane formula (based on "working level months," calculated from time spent underground and the relative toxicity of the site).
