Design Notes

This part was intended for use in pET-28c(+) for initial analysis of protein expression, and in pUS250 for final expression of a polycistronic construct incorporating PsiD, PsiK, and PsiM. To achieve this, the part was ordered in a gBlock containing BsaI sites (complementary to a BsaI site in the PsiK gBlock and to a BsaI site in the backbone of pUS250) for Golden Gate cloning, and with EcoRI and HindIII sites to enable traditional restriction cloning into pUS250. As there is a ribosomal binding site in the pET-28c(+) backbone, but not in pUS250, a RBS sequence was added to the gBlock upstream of the EcoRI site, so that it would not incorporate into pET-28c(+). The RBS sequence used was the consensus Shine-Dalgarno sequence.
