Abstract
A process is disclosed for recovering a cell wall protein, particularly a Fc-receptor, from streptococcal bacteria. In the process, streptococcal bacteria are treated with at least one proteolytic enzyme to solubilize the cell wall protein. A process is also disclosed for recovering Fc-receptor type III (protein G) having selective IgG-binding capability (i.e., no albumin-binding capability) from streptococcal bacteria by pretreating these bacteria with enzymes prior to said enzymatic solubilization.
