UniProtKB - Q86GL4 (NOXB_DICDI)
Protein
Superoxide-generating NADPH oxidase heavy chain subunit B
Gene
noxB
Organism
Dictyostelium discoideum (Slime mold)
Status
Functioni
Critical component of the membrane-bound oxidase that generates superoxide. It is the terminal component of a respiratory chain that transfers single electrons from cytoplasmic NADPH across the plasma membrane to molecular oxygen on the exterior (By similarity).
