Ampicillin resistant gene

It is also sometimes used for the treatment of urinary tract infections, meningitis, and salmonella infections, but resistance to ampicillin is increasingly common The ampicillin resistance gene (ampr) codes for an enzyme (b-lactamase) that is secreted into the periplasmic space of the bacterium where it catalyzes

The ampicillin resistance gene (AmpR) is called a selectable marker gene and is incorporated into several plasmids that are commonly used in a wide range of

14 Jun 1978 the ampicillin resistance gene of pBR322, an Escherichia coli plasmid that tional design of penicillins thatare resistant to this penicillinase How is a cell made ampicillin resistant These genes in turn encode proteins, and when a bacteria picks up a gene from the environment it can start making The pGPS3 has a deletion from BglI to BglII that destroys the ampicillin resistance gene. The ampicillin resistance gene containing the stop codon was then

28 Jun 2012 We confirmed the role of four genes in ampicillin resistance by the generation of targeted mutants and further characterized these mutants The ampicillin resistance gene ampR (also known as blaTEM1) is derived from the bacterium Salmonella paratyphi and is used as a marker gene in the
