Browse Regulatory parts!
Regulatory parts are those which provide binding regions for RNA polymerase, the enzyme which performs the act of transcription (the conversion of DNA to RNA).
Some sub-categories of Regulatory parts are:
Constitutive parts
- constituitive: parts which allow for continual transcription of parts. Often these parts can be de-activated by the addition of ligand. The use of constituitive promoters can be desirable since they are less susceptible to cross-talk and can hypothetically take in PoPS input.
Examples of constitutive parts include
- Part:BBa_R0040 - the pTet promoter region, controlled by tetracycline or its analog [http://openwetware.org/wiki/ATc ATC]
- Part:BBa_R0010 - the pLac promoter region, controlled by the lactose protein or by [http://openwetware.org/wiki/IPTG IPTG]
Inducible parts
- ligand-activated: parts which are continually "off", but allow for activation through the addition of particular chemicals
Examples include:
- Part:BBa_R0080 - The araC promoter region, which can be activated by the addition of the sugar [http://openwetware.org/wiki/Arabinose arabinose]
- Part:BBa_I0500 - Another [http://openwetware.org/wiki/Arabinose arabinose] inducible promoter region
