pKM1000

Description:	A Gateway™ destination vector for the production of recombinant proteins as fusions to the C-terminus of Thermatoga maritima maltodextrin-binding protein.
Origin:	A derivative of pET11c (Novagen)
Replicon:	ColE1
Antibotic Resistance:	Ampicillin
Promotor:	bacteriophage T7
Inducer:	IPTG (1 mM)
Notes:	The single cysteine in T. maritima MBP (residue 12) was changed to a serine by site-directed mutagenesis. Because it carries a gene (ccdB ) that encodes a lethal DNA gyrase poison, this vector must be propogated in an E. coli gyrA mutant such as DB3 or DB5 (Invitrogen), which is immune to the action of CcdB.
