BBa_K415206 1 BBa_K415206 J23117 : B0034 : cymR Repressor Protein 2010-08-19T11:00:00Z 2015-05-08T01:12:27Z This part is composed of BioBricks BBa_J23117 and BBa_K415204. This is a copy of a strongly expressed cymR repressor under the control of a weak, constitutive promoter. This is a modular component for circuit construction and a relatively strong cymR generator. true false _525_ 0 6719 9 Discontinued false 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. false Grant Robinson component2078452 1 BBa_K415202 component2078449 1 BBa_J23117 component2078451 1 BBa_B0034 annotation2078452 1 BBa_K415202 range2078452 1 62 673 annotation2078449 1 BBa_J23117 range2078449 1 1 35 annotation2078451 1 BBa_B0034 range2078451 1 44 55 BBa_K415202 1 BBa_K415202 cymR Repressor Protein 2010-08-19T11:00:00Z 2015-05-08T01:12:27Z 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." true false _525_ 0 6719 9 Discontinued false This repressor required site-directed mutagenesis of nucleotide 132 to a G in order to remove a PstI cut site. false Grant Robinson BBa_B0034 1 BBa_B0034 RBS (Elowitz 1999) -- defines RBS efficiency 2003-01-31T12:00:00Z 2015-08-31T04:07:20Z Released HQ 2013 RBS based on Elowitz repressilator. false true _1_ 0 24 7 In stock false Varies from -6 to +1 region from original sequence to accomodate BioBricks suffix. <p>No secondary structures are formed in the given RBS region.
