Crystallographic studies of Mycobacterium tuberculosis polyphosphate/ATP-NAD kinase complexed with NAD

J Biosci Bioeng. 2004;98(5):391-3. doi: 10.1016/S1389-1723(04)00302-0.

Abstract

NAD kinase from Mycobacterium tuberculosis (Ppnk) uses ATP or inorganic polyphosphate [poly(P)]. Ppnk overexpressed in Escherichia coli was purified and crystallized in the presence of NAD. Preliminary X-ray analysis of the resultant crystal indicate that the crystal belongs to hexagonal space group P6(2)22 and is holo-Ppnk complexed with NAD.
