Comparative analysis of the tubulin secondary structure

A. Yu. Niporko, Ya. B. Blum

The secondary structure of tubulin and FtsZ molecules from evolutionary distant organisms was analyzed. It was revealed that a majority of the secondary structure elements is common for all proteins investigated, but each protein has also unique structure elements. The time stability of molecules secondary structure is clearly different for the tubulin and FtsZ classes. In the case of tubulin we can speak about dynamic metastability of the secondary structure specific for these proteins.
