Figure 4.

Sequence alignment of OstrinLysC with the chicken, duck, human, housefly and lepodipteran lysozymes. Gaps are indicated by “-”, eight conserved cysteines are indicated by “#”,“-” indicates two catalytic sites in case of lysozymes of B. mori and chicken, “?” indicates another catalytic site in case of chicken lysozyme, this site may be inhabited by the salt bridge between Asp 70 and Arg 96 in B. mori. The residues corresponding to the active site in the case of tasar silkworm lysozyme are denoted with “*”. A-F indicates substrate-binding sites in the case of chicken lysozyme. Residues forming secondary structures of lysozymes in B. mori and chicken are indicated in boxes. Two loops in the secondary structures are underlined.
