Crystal structure of Heme Binding protein, an autotransporter hemoglobine protease from pathogenic Escherichia coli
Overview
The acquisition of iron is essential for the survival of pathogenic, bacteria, which have consequently evolved a wide variety of uptake systems, to extract iron and heme from host proteins such as hemoglobin. Hemoglobin, protease (Hbp) was discovered as a factor involved in the symbiosis of, pathogenic Escherichia coli and Bacteroides fragilis, which cause, intra-abdominal abscesses. Released from E. coli, this serine protease, autotransporter degrades hemoglobin and delivers heme to both bacterial, species. The crystal structure of the complete passenger domain of Hbp, (110 kDa) is presented, which is the first structure from this class of, serine proteases and the largest parallel beta-helical structure yet, solved.
