Composite part for streptomycin resistance

This composite part confers resistance to streptomycin. The part contains the constitutive promoter BBa_J23119 from the Anderson collection, BBa_B0034 ribosome binding site, BBa_K125520 coding sequence conferring resistance to streptomycin and BBa_K2797001 terminator.

Usage and Biology

A range of antibiotic resistance genes are required for selection of transformants when inserting foreign DNA into a chassis organism. Newcastle iGEM 2018 focused on developing a new chassis organism capable of colonising plant roots. The selected organism, Pseudomonas sp. strain CT364 was found to be resistant to a range of commonly used antibiotics. Streptomycin was one of two antibiotics Pseudomonas sp. was found not to be resistant to. The team has deposited a new streptomycin resistance cassette.

Figure 3 E. coli strain DH5α carrying the streptomycin resistance part BBa_K2797002 plated on LB agar containing chloramphenicol (25 μg/ml). The part is in the pSB1C3 backbone conferring resistance to chloramphenicol.

Figure 4 E. coli DH5α with or without the BBa_K2797002 (SmRp) part in pSB1C3 were grown in LB broth containing streptomycin at varying concentrations. Cells were grown in 96-well plate format in 200 μl volumes at 37 C over 24 hours. (n=3 replicates, error bars are standard error of the mean).
