Degrees of O-acetylation and cross-linking of the peptidoglycan of Neisseria gonorrhoeae during growth.
The progress of incorporation of radioactive glucosamine into the O-acetylated and non-O-acetylated sub-units of the insoluble peptidoglycan of growing Neisseria gonorrhoeae was examined. More than 80% of the final degree of cross-linking was achieved within 3 min; the remainder of the process took much longer. Rapid O-acetylation occupied up to 10 min, at which time only about 65% of the maximum value had been reached. There was thus evidence for maturation of peptidoglycan both in regard to cross-linking and to O-acetylation.
