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 bacterial protein motA [1] is required for the rotation of the flagellar motor. This protein probably forms a transmembrane proton channel used to energize the flagellar rotary motor. The motA protein is an integral membrane protein that contains four transmembrane domains.
As as signature for the motA family of proteins, we selected a conserved region that corresponds to the fourth transmembrane region.
