Abstract

The inducible -Lactamase from NCTC 8203 and the constitutive -lactamase from srrain 1822 S/H have been isolated and compared. These two enzymes are apparently perlriasmic since they are released by freezing and thawing. They resemble each other closely in their molecular weights, amino acid composition, isoelectric points and electrophoretic mobility as well as in their catalytic properties, and they may be identical. Neither enzyme contains a free thiol group.
