L1c-PsaDintron-bleRscp-ARS-MHETase-SP20-RbcS2

This vector is a part of the Chlamy-HUB-Collection. This part is composed of the PsaD promoter with an expression enhancing intron PsaDintron, the bleomycin resistance with self cleaving peptide scp, the secretion signal ARS, the MHETase enzyme, kindly provided by the TU Kaiserslautern 2019 team, the secretion enhancing SP20 glycomodule, and the Rbcs2 terminator. The part can be used to express and secrete the MHETase enzyme in C. reinhardtii. 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).
