L1c-PsaD-bleRscp-YFP-RbcS2

This vector is a part of the Chlamy-HUB-Collection. This part is composed of the PsaD promoter, a bleomycin resistance with self cleaving peptide scp, a B2-B2 linker, a YFP mVenus marker, and the Rbcs2 terminator. This Level 1 construct is designed for comparison of locus dependent expression through fluorescence intensity measuerments.

The bleomycin resistance leads to a higher expression of the enzyme, due to its working mechanism. For every two bleomycin molecules, the bleomycin resistance gene must be expressed once. The resistance works in a ratio of 1:2 to the antibiotic (Hayes et al., 1990). By having the resistance in the same open reading frame, the enzyme is also expressed, leading to a higher expression of the enzyme (Lumbreras et al. 1998).
