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

βflexiviridae are a family of plant viruses containing a single-stranded positive-sense RNA genome [E1]. The first open reading frame (ORF1) of βflexiviridae encodes a putative replication-associated protein that is autocatalytically processed by a peptidase family C23 domain [E2]. The peptidase family C23 domain is a papain-like proteinase domain with catalytic cysteine and histidine residues [1].

Some proteins known to contain a peptidase family C23 domain are listed below:

  • Blueberry scorch virus (BBScV) RNA replication protein.
  • Apple stem pitting virus (ASPV) RNA replication protein.
  • Potato virus M (PVM) RNA replication protein.

The profile we developed covers the entire peptidase family C23 domain.
