Protein Function antimicrobial activity; catalyses the hydrolysis of glycosidic bonds of mucopolysaccharides in bacterial cell walls; immune-regulatory activities, inactivation of certain viruses; antiinflammatory; antitumour
Biochemical Properties Optimum pH of 7.9 in 0.067 M phosphate buffer; require salts for activity; sodium citrate was the most potent activator of the enzyme activity; sedimentation coefficient 2S; isoelectric point to be around pH 9.5; more stable in a.IS M KC1-o.o2 :M sodium acetate buffer (pH 5.4) than in aqueous solution; labile at alkaline pH; Any treatment which "increases the acid character of the molecule decreases the enzyme's potency, and the treatments which increase its basic character increase its activity;
Significance in milk role of fighting infections in breastfeeding infants; natural antimicrobial agent;
