C-type lysozyme/alpha-lactalbumin family; Alpha-lactalbumin is the regulatory subunit of lactose synthase, changing the substrate specificity of galactosyltransferase from N-acetylglucosamine to glucose. C-type lysozymes are secreted bacteriolytic enzymes that cleave the peptidoglycan of bacterial cell walls. Structure is a multi-domain, mixed alpha and beta fold, containing four conserved disulfide bonds.

alpha lactalbumin; alpha-lactalbumin (lactose synthase B protein, LA) is a calcium-binding metalloprotein that is expressed exclusively in the mammary gland during lactation. LA is the regulatory subunit of the enzyme lactose synthase. The association of LA with the catalytic component of lactose synthase, galactosyltransferase, alters the acceptor substrate specificity of this glycosyltransferase, facilitating biosynthesis of lactose.

C-type lysozyme and alpha-lactalbumin; C-type lysozyme (chicken or conventional type, 1,4-beta-N-acetylmuramidase) and alpha-lactalbumin (lactose synthase B protein, LA). They have a close evolutionary relationship and similar tertiary structure, however, functionally they are quite different. Lysozymes have primarily bacteriolytic function; hydrolysis of peptidoglycans of prokaryotic cell walls and transglycosylation. LA is a calcium-binding metalloprotein that is expressed exclusively in the mammary gland during lactation. LA is the regulatory subunit of the enzyme lactose synthase. The association of LA with the catalytic component of lactose synthase, galactosyltransferase, alters the acceptor substrate specificity of this glycosyltransferase, facilitating biosynthesis of lactose. Some lysozymes have evolved into digestive enzymes, both in mammals and invertebrates.

C-type lysozyme; C-type lysozyme (chicken or conventional type; 1, 4-beta-N-acetylmuramidase). In humans, lysozyme is found in a wide variety of tissue types and body fluids. It has bacteriolytic properties through the hydolysis of beta-1,4, glyocosidic linkages between N-acetylmuramic acid and N-acetyl-D-glucosamine residues in a peptidoglycan, as well as between N-acetyl-D-glucosamine residues in chitodextrins. This family also includes digestive stomach lysozyme, which allow ruminants to digest bacteria in the foregut. The mammalian enzyme is related to lysozyme found hen egg-whites and related species.

C-type invertebrate lysozyme; C-type lysozyme proteins of invertebrates, including digestive lysozymes 1 and 2 from Musca domestica, which aid in the use of bacteria as a food source. These lysozymes have high expression in the gut and optimal lytic activity at a lower pH. Other lysozymes in this subfamily have immunological roles. e.g. Anopheles gambiae has eight lysozymes, most of which seem to have immunological roles, those some may function as digestive enzymes in larvae. C-type lysozyme (chicken or conventional type; 1, 4-beta-N-acetylmuramidase) has bacteriolytic properties through the hydolysis of beta-1,4, glyocosidic linkages between N-acetylmuramic acid and N-acetyl-D-glucosamine residues in a peptidoglycan, as well as between N-acetyl-D-glucosamine residues in chitodextrins.
