Name | Hypovirulence-associated virus (HAV) papain-like protease p29 domain |
| Function | The HAV papain-like protease p29 is a cysteine protease, which forms the peptidase family C7. A Cys and a His catalytic residue are essential for autocatalytic cleavage at a glycine dipeptide clevage site located at the C- terminus of the domain. |
| Scope(s) |

Comments
[?]
| FUNCTION | Papain-like protease p29 is a cysteine protease of the peptidase family C7 that contributes to hypovirulence-associated traits like the reduction in conidiation and laccase activity, but not to virulence attenuation. Acts as suppressor of RNA-mediated gene silencing, also known as post-transcriptional gene silencing (PTGS), a mechanism of viral defense that limits the accumulation of viral RNAs. Enhances viral dsRNA accumulation and virus transmission. Also involved in the reduction in orange pigmentation of the host, an effect independent of the intrinsic protease activity. |
