Abstrakt: The codA gene of Corynebacterium glutamicum PCM 1945 coding for a creatinine deiminase (CDI) (EC 3.5.4.21) has been amplified and cloned. The recombinant strain of Escherichia coli that overproduces the (His) 6 -tagged inactive CDI of C. glutamicum as inclusion bodies has been constructed. After solubilization of inclusion bodies in the presence of 0.3% N-lauroylsarcosine, the enzyme was renaturated and purified by a single-step procedure using metal-affinity chromatography. The yield of the (His) 6 -tagged CDI is ~30 mg from 1 L culture. The purified enzyme is sufficiently stable under the conditions designed and possesses an activity of 10-20 U/mg. The main characteristics of the tagged enzyme remained similar to that of the natural enzyme.
