39C Temperature-Sensitive mScarlet-I pdt#3
Medium-weak 39C Temperature-Sensitive mScarlet-I pdt#3. Components: J23107 TPL + ptlpA b0034m mScarlet-I pdt#3
Mechanics
J23107, a medium-weak constitutive promoter, constitutively expresses TlpA39. Unlike the original TlpA, TlpA39 undergoes a conformational change at 39C and loses its ability to bind the downstream pTlpA. Therefore, TlpA39 halts its repression of pTlpA at temperatures above 39C, inducing the expression of the rapidly-maturing mScarlet-I. The mScarlet-I in this circuit has a pdt degradation tag, allowing for degradation by the mf-Lon protease. Specifically, this circuit contains pdt#3, the strongest degradation tag from part series K2333401-K2333406 or K2333401.
As an IFFL
In this circuit, heat activates a reporter, mScarlet-I. In a complete IFFL (incoherent feed forward loop), an input must activate both a reporter and its inhibitor. Therefore, this circuit requires mf-Lon (or a different inhibitor of mScarlet-I) to act as an IFFL.
