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

Name Gammma-tocopherol O-methyltransferase (gTMT)
Function Tocopherol O-methyltransferase (EC 2.1.1.95) is an enzyme that transfers a methyl group from S-adenosyl-L-methionine (SAM) to gamma- tocopherol to form alpha-tocopherol and S-adenosyl-L-homocysteine. The cyanobacterial orthologue sll0418 (EC 2.1.1.295) methylates 2-methyl-6- phytyl-1,4-benzoquinone/2-methyl-6-solanyl-1,4-benzoquinone (MPBQ/MSBQ) to yield 2,3-dimethyl-5-phytylbenzoquinone/2,3-dimethyl/plastoquinol-9.
