Discovery of pH-dependent 'switch' in interaction between pair of protein molecules

All biological processes are in some way pH-dependent. Human bodies and those of other organisms need to maintain specific and constant pH regulation in order to function. Changes in pH can have serious biological consequences—or serious benefits, as researchers at the Qingdao Institute of Bioenergy and Bioprocess Technology (QIBEBT), Chinese Academy of Sciences (CAS) found. The findings are published on Oct. 23 in the journal Science Advances. Cellulosomes are extracellular complexes consisting of multiple enzymes, which are associated with the cell's surface. Within the cellulosome...
