Fet3p (original) (raw)

Fet3p is a multicopper oxidase (MCO)2 found in Saccharomyces cerevisiae with a structure consisting of three cupredoxin-like β-barrel domains and four copper ions located in three distinct metal sites (T1 in domain 3, T2, and the binuclear T3 at the interface between domains 1 and 3). Fet3p is a type I membrane protein with an orientation that places the amino-terminal oxidase domain in the exocellular space (Nexo) and the carboxyl terminus in the cytoplasm (Ccyt).
