M. tuberculosis Gyrase (HIS)
Mycobacterium tuberculosis gyrase is a bacterial type II topoisomerase which can introduce negative supercoils into DNA. It is a target antibacterial drugs and can be used for screening potential novel antibacterial compounds. It is prepared by overexpressing the subunits with C-terminal polyhistidine tags in E. coli and then purified by affinity chromatography.
It is supplied as an A2B2 complex at a concentration of 10 U/µl in Dilution Buffer. Store at -80 °C.
All enzyme is supplied with 5X concentrated Assay Buffer and Dilution Buffer which are also available separately. 1 U of gyrase will supercoil 0.5 µg relaxed pBR322 DNA in 30 minutes at 37 °C.
