pneumococcal autolysins are enzymes involved in cell wall turnover and cellular division physiologically. they have been found to be involved in the pneumococcus pathogenesis. the aim of this study was to identify the autolytic activity of spr1754 as a novel protein of streptococcus pneumoniae . moreover, the binding of the recombinant protein to plasma proteins was also determined. the spr1754...

introduction: mcp (membrane cofactor protein or cd46) is a complement regulatory proteins (crps), which is present in most of body cell membranes (except erythrocytes), and also in most biologycal body fliuds. due to the important role of this protein in the complement system, specially in fertility, the aim of this study was to determine and isolate this protein in human seminal plasma. materi...

  Objective(s): Echis carinatus is one of the venomous snakes in Iran. The venom of Iranian Echis carinatus is a rich source of protein with various factors affecting the plasma protein and blood coagulation factor. Some of these proteins exhibit types of enzymatic activities. However, other items are proteins with no enzymatic activity.   Materials and Methods: In order to study the mechanism ...
