Cell Research

Invertebrate lysozyme (I - lyz or destabilase) exist in shrimp. The protein may have a function as a peptidoglycan break enzyme and as a peptide enzyme. Shrimp usually vibrio infection. , gram negative bacteria, as is known to all, c - lyz (similar to the chicken lysozyme) is active against these bacteria. In order to further understand renaturation of rules, we determine the sequences of genes and protein structure I - lyz modeling. In addition, I - lyz expression and c - lyz response lipopolysaccharide (LPS) was studied. Shrimp I - lyz gene is made up of two introns interrupt to standardize joint connection. Expression of shrimp I - lyz is transient cut injection followed by after LPS induced after 6 hours in hepatopancreas. By contrast, c - lyz is raised hepatopancreas 4 h post injection and trimmed in gill. L. vannamei I - lyz does not contain of lysozyme catalytic residues (glycohydrolase) is not isopeptidase activities; However, as is known to all, antibacterial activities not only rely on the enzyme activity of protein. Research invertebrates lysozyme will increase our understanding of the regulatory process defense mechanism.
