The serum exhibited lytic activity, but not the leukocyte extracts. The lytic substance in the serum was of approximately 14 kDa and the N-terminal amino acid sequence was YVYSK. cDNA cloning identified a C-type lysozyme (TsLysC) gene and two G-type lysozyme (TsLysG) cDNA clones of different lengths. The TsLysC gene encodes 149 amino acids residues, and the sequence derived from the N-terminal amino acid sequencing was displayed at position 17–21. TsLysG, on the other hand, contains two ORFs that are homologous to the N- and C-terminal regions of G-type lysozyme of other fish species. TsLysC mRNA levels were high in the liver. TsLysG mRNA level was significantly lower than TsLysC mRNA in the liver., 公開日: 2023-06-04, 18H03958}, title = {Chicken-type lysozyme is a major bacteriolytic enzyme in the blood of the banded houndshark Triakis scyllium}, volume = {134}, year = {2022} }
