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.
Amos Bairoch

Data class Domain;
Predictors PROSITE; PS52044; VLRF1
Name Vms1-like release factor 1 (VLRF1) domain
Function The ANKZF1/Vms1 Vms1-like release factor 1 (VLRF1) domain, which acts as a peptidyl-tRNA hydrolase, has a catalytic loop bearing a conserved glutamine. In addition to the glutamine in the active site, the VLRF1 domain also contains conserved vicinal arginines in the alpha-helix immediately following the active-site loop. The cleavage mechanism involves remodelling and cleavage of the ribose-phosphate backbone of the tRNA by a tyrosine and the GSQ motif.
Scope(s) Eukaryota
Example(s) Q80UU1;
