Biofilms are assemblages of bacteria embedded within a matrix of extracellular polymeric substances (EPS) attached to a substratum. The process of biofilm formation is a complex phenomenon regulated by the intracellular and intercellular si...
Structure and function of ClpXP, a AAA+ proteolytic machine powered by probabilistic ATP hydrolysis [0.03%]
ClpXP的结构与功能研究:一种由概率水解ATP驱动的AAA+蛋白酶体
