The bacteriolytic activity of native and covalently immobilized lysozyme against Gram‐positive and Gram‐negative bacteria is differentially affected by charged amino acids and glycine

open access: yesFEBS Open Bio, Volume 9, Issue 3, Page 510-518, March 2019., 2019
Certain amino acids increase the bacteriolytic activity of native lysozyme. The effect is significant in the case of Escherichia coli lysis and less pronounced in the case of Micrococcus luteus lysis. When lysozyme is immobilized, the stimulating effect exerted by the presence of amino acids decreases or disappears altogether.
