1.C.12.1.9
The cholesterol-dependent pore-forming cytoslysin, Pyolysin of 534 aas with one N-terminal TMS.  The pathology of Trueperella pyogenes and this pyolysin have been described and reviewed (Rzewuska et al. 2019). Liu et al. 2022 located and mutated two different highly conserved structural sites in the primary sequence of the protein that are critical for PLO structure and function.
