Figure 2: Two views of the crystal structure of CD38 complexed with nanobodies related by 180° rotation around a vertical axis.
From: Immuno-targeting the multifunctional CD38 using nanobody

Three different nanobodies (shown in ribbon mode; orange: 375; cyan: 551; green: 1053) are composed with CD38 (shown in surface mode). The residues of the epitopes are colored both in the structure and in the listed sequence.
