Isolation of <i>Escherichia coli</i> K-12 Mutants with Altered Levels of β- <i>N</i> -Acetylglucosaminidase

Abstract

Eight mutants with less than 25% of the wild-type level of beta-N-acetylglucosaminidase activity have been isolated from Escherichia coli K-12. Studies on these mutants suggest that less than 1% of the wild-type level of this enzyme may be adequate for the normal growth and division of E. coli cells.
