Recombineering provides the ability to make rapid, precise, and inexpensive genetic alterations to any DNA sequence, either in the chromosome or cloned onto a vector that replicates in E. coli (or other recombineering-proficient bacteria), and to do so in a highly efficient manner.
DNA repair-proficient bacteria which are unable to protect their proteins from ionizing radiation-induced ROS succumb to relatively minor DNA damage [1], [4], [5].
This structural stability in M. tuberculosis is more pronounced than in the mismatch repair-proficient bacterium E. coli.
However, it is important to mention that we identified two CF patients that harbored QS-proficient DK-2 bacteria, suggesting that several evolutionary lineages develop in the CF population as recently published by Wilder [36].
Monitoring biofilm growth of lysogenic and non-lysogenic pneumococcal strains indicated that phage-infected bacteria are more proficient at forming biofilms, that is their biofilms are characterized by a higher biomass and cell viability.
In nature, D. discoideum cells are proficient phagocytes that feed on soil bacteria.
Soil bacteria and fungi are particularly proficient at producing natural chemical weapons, apparently as part of a subterranean arms race to spew out toxic chemicals to kill rival species.
However, the RecBC proteins (RecBCPs and RecBCEc) of the two bacteria are not equivalent; the RecBCEc is proficient in DNA recombination and repair, and supports the growth of P. syringae at low temperature, while RecBCPs is insufficient for these functions.
Streptomycetes are common saprophytic soil bacteria that constitute some of the most proficient producers of naturally occurring therapeutic molecules like antibiotics, immunosuppressants and anti-cancer agents [ 1].
In bacteria, synthetic minimal RNase P RNAs consisting only of these core sequences and structures were shown to be catalytically proficient.
Julian was immediately proficient, practical.
