The QR codes that link to the data to display Figures 1a–d, 2b, and 3a,b in the augment app in augmented reality had to be changed since the links were not working anymore on certain mobile devices. In this corrigendum, updated QR codes have been supplied that ensure a future-proof application. Figure 1. Examples of three-dimensional structural representations of protein molecules. (A) The active site of the epidermal growth factor receptor (EGFR) kinase domain bound covalently via Cys797 to a pyrazolopyrimidine inhibitor (PDB ID 5j9y; 2FO–FC map contoured at 1σ). (B) Small molecule inhibitor bound to the lipophilic binding pocket of the kinase p38α. Surrounding secondary structure elements (αEF/αF loop and helices 1L14 and 2L14) and amino acids (Trp197, Lys249, Ser251, and Asp294) involved in binding are shown. The 2FO–FC electron density is depicted as a mesh at 1σ (PDB ID 5n67). (C) The small GTPase Rab1b bound to guanosine-5′-[β,γ- imido]-triphosphate (GppNHp) and Mg2+ (green sphere) in the active site and covalently modified with adenosine-5′-monophosphate at Tyr77 (the important switch I (red), switch II (blue), and P-loop (magenta) are highlighted; PDB ID 3nkv). (D) Model of the transcription factor Nrf2 (cartoon) bound to the major groove of a short stretch of DNA (surface representation) highlighting important basic residues that are presumably involved in recognition of the nucleic acid and interaction with the negatively charged phosphate groups of the DNA (the model is based on PDB ID 1skn). Figure 2. Simple visualization of complex stereochemistry. The small molecule X-ray structure of morphine including five asymmetric carbon atoms (∗) shown as a two-dimensional figure (A) and the corresponding Ortep plot (CCDC identifier EFASAH15). (B) The view in 3D AR allows the reader to directly appreciate the complex stereochemistry of this molecule (carbon, gray; oxygen, red; nitrogen, blue; Cl–, green). Figure 3. Large molecular assemblies can also be visualized in augmented reality. (A) Cartoon representation of the pentameric toxin TcdA1 (PDB ID 4o9y) in two different orientations (the monomers are shown in orange, purple, gray, turquoise, and green and consist of ∼2500 amino acids each). Note the long channel within the pentamer of the protein that is used to funnel the toxin into infected cells. (B) The RNA-polymerase III open preinitiation complex (PDB ID 6eu0). The structure was obtained by cryoelectron microscopy and shows the polymerase bound to the partially unwound DNA and Mg2+ in the active site. The authors are sorry for any inconvenience caused.
