In vitro construction of deletion mutants of the bacteriocinogenic plasmid Clo DF13.

abstract：:Population-scale sequencing is increasingly uncovering large numbers of rare single-nucleotide variants (SNVs) in coding regions of the genome. The rarity of these variants makes it challenging to evaluate their deleteriousness with conventional phenotype-genotype associations. Protein structures provide a way of addr...
