S. elongatus PCC7942 psbAI promoter

Our part is the Synechococcus elongatus promoter for gene psbAI. This promoter works on a constitutive way, althought its activity can be enhanced or decreased in the presence or absence of light (in nature it works regulated in a circadian cicle). This part is suitable for building light-induced devices.



BBa_K754000 UsageAndBiology Not understood The psbAI gene of the cyanobacterium Synechococcus elongatus PCC 7942 is one of three psbA genes that encode a critical photosystem II reaction center protein, D1. Regulation of the gene family in response to changes in the light environment is complex, occurs at transcriptional and posttranscriptional levels, and results in an interchange of two different forms of D1 in the membrane. Expression of psbAI is downregulated under high-intensity light (high light) in contrast to induction of the other two family members.
