Function

[LYSC_CHICK] Lysozymes have primarily a bacteriolytic function; those in tissues and body fluids are associated with the monocyte-macrophage system and enhance the activity of immunoagents. Has bacteriolytic activity against M.luteus.^[1]

Publication Abstract from PubMed

Glycine amide (GlyAd), a typically amidated amino acid, is a versatile additive that suppresses protein aggregation during refolding, heat treatment, and crystallization. In spite of its effectiveness, the exact mechanism by which GlyAd suppresses protein aggregation remains to be elucidated. Here, we show the crystal structure of the GlyAd-lysozyme complex by high resolution X-ray crystallographic analysis at a 1.05A resolution. GlyAd bound to the lysozyme surface near aromatic residues and decreased the amount of bound waters and increased the mobility of protein. Arg and GlyAd molecules are different in binding sites and patterns from glycerol and related compounds, indicating that decreasing hydrophobic patches might be involved in suppression of protein aggregation.
