Depositor Comments

Genotype = glyA
Precursor strain = BL21 CodonPlus (DE3)-RIL
Selective amino acid labeling (and/or requirement) = Gly

Each target gene was deleted from the chromosome of BL21 (DE3) E. coli strain using λ-Red recombination system.

Supplemental documents contain a list of PCR primers used for verification of each knocked-out gene as well as an image showing PCR results for this strain.
