Publikováno v: Extremophiles. 13:1-10
The complete genome analysis of the archaeon Thermoplasma volcanium has revealed a gene assigned to encode the histone-like DNA-binding protein HU. Thermoplasma volcanium is a moderate thermophile growing around 60 degrees C and it is adaptable to ae

Ab initiodetermination of a crystal structure by means of the Schrödinger equation
Autor: G. Tsoucaris, Pavlos Tzamalis, Kostas Bethanis, A. Hountas
Publikováno v: Acta Crystallographica Section A Foundations of Crystallography. 58:265-269
It is shown that the use of the Schrödinger equation may lead to the ab initio determination of the positions of the nuclei in a crystal, given a limited number of diffracted-beam intensities. In particular, it is shown that an extremely simplified

New developments of the TWIN algorithm for phase extension and refinement in disordered supramolecular structures
Autor: A. Hountas, D. Mentzafos, Kostas Bethanis, Pavlos Tzamalis, Areti Kokkinou, G. Tsoucaris
Publikováno v: Acta crystallographica. Section A, Foundations of crystallography. 56(Pt 6)
A new development of the TWIN algorithm is described and used for phase extension/refinement in supramolecular complexes. A small number of phased reflections at low resolution are sufficient for the quasi-automated determination of all atomic coordi
