J23117 : B0031 : cymR Repressor Protein [Weak cymR Generator]

2015-05-08T01:12:27Z
This part consists of BioBricks BBa_J23117 and BBa_K415203.
This is a copy of a moderately expressed cymR repressor under the control of a weak,
constitutive promoter. This is a modular component for circuit construction and a weak
cymR generator.

Note that a weak promoter was chosen in order to follow the construction design of Choi, et
al. in the 2010 paper, "A novel, versatile, and tightly regulated expression system for E. Coli
strains." Previous work by Choi and others in M. Extorquens indicated that overexpression
of cymR was potentially toxic to bacterial cells; although data concerning this toxicity is
unavailable, the researchers managed to develop a tightly expressed cymR switch by placing
cymR under the control of a weak, constitutive promoter for kanamycin resistance. As our
team was unable to clarify the origin of this sequence, we instead selected a weak, constitutive
promoter from the Anderson library.

cymR Repressor Protein

CymR was derived from the organism Pseudomonas Putida. The copy of cymR used in the construction of BBa_K415202 was generously donated by Noah Davidsohn.
The cymR repressor tightly and efficiently binds the cmt operator. In conjunction with part
BBa_K415200, this repressor may be used to create an inverter or similar logical circuitry. cymR
changes conformation upon induction with cumate (isopropylbenozate), and may be used in a
manner similar to the lacI/IPTG system.
The cymR repressor appears to bind the complementary cmt operator more efficiently than
lac repressor binds the lac operator, according to Choi, et al. in a recent (as of 2010) paper titled, "A novel, versatile, and tightly regulated expression system for E. Coli strains."

This repressor required site-directed mutagenesis of nucleotide 132 to a G in order to remove
a PstI cut site.

<P> <P>Varies from -6 to +1 region from original sequence to accomodate BioBricks suffix ("RBS-1" in figure 4-14 of thesis). <p>No secondary structures are formed in the given RBS region. Users should check for secondary structures induced in the RBS by upstream and downstream elements in the +50 to -50 region, as such structures will greatly affect the strength of the RBS. <P>
