We are deeply saddened by the passing of Amos Bairoch (1957–2025), the creator of PROSITE. We wish to dedicate our latest paper, published shortly before his death, to him. He will always be a source of inspiration to us.
Our deepest condolences go out to his family and friends, and to all those who had the privilege of working with him. Rest in peace, Amos. Your work will live on long after you are gone.

Description

Pestiviruses [E1] are animal pathogens that are recognized as a separate genus of the family Flaviviridae. The pestiviral genome is a single-stranded RNA of positive polarity. It is translated into a large polyprotein, which is cotranslationally and posttranslationally processed by viral and cellular proteases. Pestivirus nonstructural protein 2 (NS2) is predicted to have a multidomain organization. The C-terminal-most domain of NS2 is a cysteine autoprotease responsible for NS2-3 cleavage. The catalytic triad is formed by His, Glu, and Cys. The pestivirus NS2 protease domain contains five Cys and one His organized in a linear fashion, suggesting the presence of a mononuclear ZnB site [1]. The pestivirus NS2 protease domain forms peptidase family C74 [E2].

The profile we developed covers the entire pestivirus NS2 protease domain.
