摘要
Increased levels of a 65-kDa stress protein (Msp65) were observed in group B Neisseria meningitidis grown under stationary-growth conditions. Electron microscopy showed two apposing rings of seven subunits, a structure typical of Escherichia coli GroEL. Msp65 was not found in either the periplasmic space or the outer membrane. Several important differences between the GroEL analogs of N. meningitidis and Neisseria gonorrhoeae are discussed.
