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

The PAW domain (present in PNGases and other worm proteins) is found as a single copy at the C-terminus of metazoan peptide:N-glycanase (PNGase) and in multiple copies in hypothetical Caenorhabditis elegans proteins peptide:N-glycanases (PNGases) [1]. The C-terminal PAW domain of PNGase binds to the mannose moieties of N-linked oligosaccharide chains [2].

The PAW domain is a slightly elongated molecule and displays a β-sandwich architecture, which is composed of two layers, containing nine and eight antiparallel β-strands, respectively, and three additional short helices (see <PDB:2G9G>) [2].

Some proteins known to contain a PAW domain are listed below:

  • Animal peptide:N-glycanase (PNGase) (EC 3.5.1.52), catalyzes the deglycosylation of several misfolded N-linked glycoproteins by cleaving the bulky glycan chain before the proteins are degraded by the proteasome.
  • Caenorhabditis elegans putative uncharacterized protein C17B7.5.

The profile we developed covers the entire PAW domain.
