TaqI Composite
This sequence codes for the restriction enzyme TaqI and also includes and RBS and double terminator which will result in a closed transcriptional unit once this construct is ligated downstream of a promoter.
Detail
This is a Type II restriction enzyme that recognises the sequence TCGA. Its activity can be blocked by dam methylation.
The working temperature is 65°C.
As part of the Imperial 2009 iGEM E.ncapsulator project, TaqI was used along with DpnII to cut up the genetic material within the cell, completing the cell death module.
Usage and Biology
The restriction enzyme TaqI, is isolated from the bacterium Thermus aquaticus. 1
It cuts at a site that is near to where early and late messenger RNA transcription starts in opposite directions. Furthermore, it is a 4 base cutter, leaving a 2 base overhang.
The cutting site is as shown:
