| novel dna packaging recognition in the unusual bacteriophage n15. | phage lambda's cosb packaging recognition site is tripartite, consisting of 3 ters binding sites, called r sequences. ters binding to the critical r3 site positions the terl endonuclease for nicking cosn to generate cohesive ends. the n15 cos (cos(n15)) is closely related to cos(λ), but whereas the cosb(n15) subsite has r3, it lacks the r2 and r1 sites and the ihf binding site of cosb(λ). a bioinformatic study of n15-like phages indicates that cosb(n15) also has an accessory, remote rr2 site, wh ... | 2015 | 25956737 |
| rapid quantification of mutant fitness in diverse bacteria by sequencing randomly bar-coded transposons. | transposon mutagenesis with next-generation sequencing (tnseq) is a powerful approach to annotate gene function in bacteria, but existing protocols for tnseq require laborious preparation of every sample before sequencing. thus, the existing protocols are not amenable to the throughput necessary to identify phenotypes and functions for the majority of genes in diverse bacteria. here, we present a method, random bar code transposon-site sequencing (rb-tnseq), which increases the throughput of mut ... | 2015 | 25968644 |
