¹H, ¹³C and ¹⁵N resonance assignments for the full-length mammalian cytochrome b₅ in a membrane environment.

Microsomal cytochrome b5 plays a key role in the oxidation of a variety of exogenous and endogenous compounds, including drugs, fatty acids, cholesterol and steroid hormones. To better understand its functional properties in a membrane mimic environment, we carried out high-resolution solution NMR studies. Here we report resonance assignments for full-length rabbit cytochrome b5 embedded in dodecylphosphocholine micelles.
