l-Histidinol dehydrogenase from Brucella suis (BsHDH) is an enzyme involved in the histidine biosynthesis pathway which is absent in mammals, thus representing a very interesting target for the development of anti-Brucella agents. In this paper we report the crystallographic structure of a mutated form of BsHDH both in its unbound form and in complex with a nanomolar inhibitor. These studies provide...
Carbonic anhydrases (CAs) catalyze with high efficiency the reversible hydration of carbon dioxide, an essential reaction for many biological processes, such as photosynthesis, respiration, renal tubular acidification, and bone resorption. Diatoms, which are one of the most common types of phytoplankton and are widespread in oceans, possess CAs fundamental for acquisition of inorganic carbon. Recently,...
The detoxification from peroxides in Sulfolobus solfataricus is performed by the Bacterioferritin comigratory proteins (Bcps), Bcp1 (Sso2071), Bcp2 (Sso2121), Bcp3 (Sso2255) and Bcp4 (Sso2613), antioxidant enzymes belonging to one of the subfamilies of the Peroxiredoxins. In this paper we report on the functional, structural and docking analyses of Bcp4, characterized by the CXXXXC motif in the active...
