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 SpoVT-AbrB domain is a DNA-binding domain found in a large protein superfamily [1,2], which includes:

  • Bacterial antibiotic resistance protein B (AbrB), a transition-state regulator.
  • Bacterial SpoVT, a late sporulation factor that modulates forespore- specific sigma G-dependent transcription.
  • Bacterial PrlF, an antitoxin component of a toxin-antitoxin (TA) module.
  • Bacterial transcription factors (antitoxins) of plasmid maintenance systems (VapB, MvpT, VppA ,VagC, PemI, MazE, ChpS).
  • Bacterial transcriptional regulator MraZ, involved in the expression of the division and cell wall (dcw) cluster. It contains two copies of the SpoVT- AbrB domain.
  • Bacterial endoribonuclease SymE.
  • Sulfolobus solfataricus repressor-like proteins SSo7c3 and SSo7c4.

The SpoVT-AbrB domain contains four β strands and one α helix and can be described as a pair of β hairpins linked by the α helix (see <PDB:1YSF>) [1,2].

The profile we developed covers the entire SpoVT-AbrB domain.
