Based on the model, the total mutation count for the library containing 100 random plaques was estimated to be 55 mutations.
Another houses a personal library containing hundreds of volumes.
In addition to preservation of the wild species accessions, a comprehensive mutant population has been developed (Menda et al., 2004) (http://zamir.sgn.cornell.edu/mutants/), which is an isogenic tomato 'mutation library' containing a total of 13 000 M(2) families derived from treatment with EMS (ethyl methane sulfonate) and fast-neutron mutagenesis.
In order to determine whether the mutation changed the substrate specificity of the enzyme, we tested the P2 P4 sites in the V266E mutants using a positional scanning peptide library containing an aspartate residue fixed in the P1 position.
Next, we tried to confirm that the deletion mutations of selected genes are indeed responsible for the reduced biofilm formation by transforming with the plasmid clone of ASKA library containing each corresponding wild-type gene.
Twenty-four libresultedesulted after barcoding, with each library containing 21 isolates with different P1 barcodes.
Select the library containing the file you want to play.
We present evidence for piggyBac element remobilization in the latter parasites and therefore such parasites can be effective tools for generation of mutant parasite libraries containing random mutations.
Nearly all mutant clones in each library contained unique mutations, indicating that mutants in the library were generated at random.
The resulting library contained, on average, 2.2 amino acid mutations per protein, as determined by sequencing randomly selected acrB variants.
SP13 was the only serine protease in our Protobothrops library that showed this His → Arg mutation (Additional file 12: Figure S5, position 126); however, the Ovophis library contained eight transcripts with His → X substitutions (Additional file 12: Figure S5, position 101).
