    Functional analysis of CYP4B1 enzymes from apes and humans uncovers evolutionary hot spots for adaptations of the catalytical function. by Saskia Hüsken, Annika Röder, Johannes Ptok, Anne E Meyer, Mats Georg, Yannick Schwarz, Christian Roos, Kerstin Mätz-Rensing, Michael C Hutter, Doreen M Floss, Allan E Rettie, Marco Girhard, Helmut Hanenberg, Constanze Wiek

    Published 2025-06-01
    “…However, due to a single amino acid change (p.P427S) within the evolutionary conserved meander region no catalytic activity of the native human CYP4B1 has been identified so far. To identify at which point in human evolution the loss of CYP4B1 activity had occurred, we evaluated the activities of CYP4B1 orthologs from 14 primate genera against 4-ipomeanol and perilla ketone in human liver cells. …”
