Function
NCZS_STRCZ NCS has antibiotic activity (for Gram-positive bacteria) and antitumor activity (for certain mouse tumors). NCS binds non-covalently to a chromophore which is the cytotoxic and mutagenic component of the antibiotic. The chromophore binds to DNA as a weak intercalator and causes single- and double-strand breaks.
Publication Abstract from PubMed
The natural complex Neocarzinostatin comprises a labile chromophore noncovalently bound to an 11.2 kDa protein. We present the first high-resolution structure of a novel complex derived from the recombinant apoprotein bound to a non-natural synthetic chromophore. Fluorescence and nuclear magnetic resonance spectroscopy were used to probe the strength and location of binding. Binding occurred in a location similar to that observed for the chromophore in the natural Neocarzinostatin complex, but with a distinct orientation. These results provide structural evidence that the apoprotein can readily accommodate small druglike entities, other than the natural chromophore within its binding cleft. The clinical use of the natural complex described by others, together with the results reported here, suggests potential applications for small molecule binding by apo-Neocarzinostatin.
