Lac operator library

Parts K079045 through K079048 are libraries intended to introduce standardization and modularity for operator sequences. Each of the 4 collections has a different repressor specificity (Lac, Tet, Lambda and LexA) and consists of 3 different members with distinct binding affinities. Since operators flanked by Biobrick ends are unpractical and costly to obtain, both by dna sinthesys and phosphorylated oligos, we designed a "Standard Collection Vector".

This layout allows to get multiple small sequences with a single synthesis process and specifically enable the extraction of one or a combination of operators using exclusively Biobrick prefix and suffix restriction enzymes. Digestion and religation of the collection vector with Xba and Pst yields a single Operators 1 and Operator 3 vectors respectively (Es: Lac2 and Lac Symmetric) avoiding the troubles and optimization related to the run and purification of very small bands on agarose gel.

A similar approach using EcoRI give rise to a multiple Operator Vector comprising Operator 1 and Operator 2 sequences, usable per se as a composite regulatory site or further restrictable with PstI to extract the single Operator 2 (Es: Lac1)

The Libraries have been syntetized by Geneart in their standard pGA18 and pMA synthesis vector, with both ColE1 high copy number origin of replication and Ampicillin resistance.

	LAC LIBRARY
	Lac1
	Lac2
	Lac SymL


	TET LIBRARY
	TeT O
	TetO-4C
	TetO-wt/4C5G


	LAMBDA LIBRARY
	Lambda OR1
	Lambda OR2
	Lambda OR3


	LEXA LIBRARY

	LexA 2

Right now we're ultimating the design and testing of an equally [http://2008.igem.org/Team:Bologna/Wetlab#Operator_site_cloning_in_standard_plasmids simple protocol] to transfer operator sequences in Biobrick Standard Assembly Vectors using standard cloning reagents and avoiding as much as possible experimentally fragile or optimization dependent steps.
