pbpG Downstream Homology
Contents
Usage and Biology
The pbpG gene codes for a penicillin-binding protein that increases ADP1’s resistance to β-lactam antibiotics. Thus deleting the pbpG gene makes ADP1 more susceptible to ampicillin, carbenicillin, and other β-lactams. Additionally, the pbpG gene is non-essential for ADP1’s survival and serves as an ideal location for inserting genetic constructs.
Design
The pbpG upstream homology part comprises the 1019 base pair region directly upstream of the pbpG gene in ADP1. This part has bsaI and bsmbI restriction sites attached to the 3’ end which are designed to delete pbpG through a two-step process involving selection and counterselection.
BsaI Restriction Site
The bsaI site is designed to ligate to the 5’ end of the tdk/kan cassette (BBa_K4342000) creating the pbpG tdk/kan cassette composite part (BBa). This composite part permits the selection of transformants through kanamycin resistance.
Bsmbi Restriction Site
The bsmbI site is designed to ligate to the 5’ end of the pbpG downstream homology (BBa_K4342012) creating the ΔpbpG homologies composite part (BBa). This composite part permits the counterselection of transformants when plating on Azidothymidine (AZT).

This part was designed to ligate to the tdk/kan cassette and the ACIAD2049 Downstream Homology via bsaI and bsmbI digestions.
