permease in American English
(ˈpɜːrmiˌeis, -ˌeiz)
noun
Biochemistry
any of the proteins that mediate the transport of various molecules across biological membranes
Word origin
[‹ F perméase (1956), equiv. to permé(able) permeable + -ase-ase]-ase is a suffix used in the names of enzymes. Other words that use the affix -ase include: amylase, hyaluronidase, ligase, oxidase, peroxidase
