AaMco1 presents a predicted N-terminal transmembrane helix and lacks the COOH-terminal transmembrane domain common to ferroxidases 16020 -, 744437 1.16.3.1 plasma membrane Fet31 and Fet34, both localize to the yeast plasma membrane 5886 716270 1.16.3.1 plasma membrane Fet3p has 11 crystallographically mapped N-linked core glycan units. Assembly of four of these units is specifically required for localization of Fet3p to the plasma membrane. Fet3 protein lacking any one of these glycan units is found in an intracellular high-molecular mass species, overview 5886 716849 1.16.3.1 plasma membrane outer surface 5886 659524 1.16.3.1 thylakoid membrane possible localization of the protein at the thylakoid membranes due to presence of a long hydrophobic N-terminal tail 42651 714969
