MACROM
Crystallography, Structure and Function of Biological Macromolecules :
The MACROM group works in the area of understanding the three-dimensional structure of biomolecules by using single-crystal X-ray diffraction techniques to study the structure of DNA and its interactions with drugs, ions and proteins.
This group uses two complementary methodologies: crystallography and recombinant DNA techniques.
Crystallography studies require the molecules to be crystallized from extremely pure samples. The best crystals are selected using an optical microscope and are frozen with liquid nitrogen.
X-ray diffraction of these crystals is carried out in the ALBA synchrotron, keeping the crystlas under a continuous supply of liquid nitrogen. The diffraction obtained is processed with the aid of specific programs in order to determine the 3-D structure of the study sample. This method has been used to study a large number of synthetic oligonucleotides, which have provided valuable information on new forms of DNA (Hoogsteen, recombinant-like, superhelixes, etc.). Our research is readily applicable to areas such as pharmaceuticals, medicine and obtaining new materials and nanotechnology.
