WebMicrobial Opsin Plasmids; Optical Switch Plasmids; Background. Optogenetics plasmids encode proteins that are controlled by light. Many of these plasmids encode for microbial opsins, which are membrane channels and pores derived from algae and archaebacteria, that can be opened and closed in response to light. http://neuroscience.openetext.utoronto.ca/chapter/3-2-molecular-toolbox-neural-circuits-the-basics/
