Fig. 4: Comparison between immature and mature HERV-K CA.
From: Molecular architecture and conservation of an immature human endogenous retrovirus

a Overlay of the immature HERV-K structure (NTD blue, CTD orange, h12 red) with mature HERV-K (gray, PDB: 6SSM), aligned to the NTD (left), CTD (middle), and NTD/CTD separately (right). b, c Arrangement of HERV-K immature (b) and mature (c) lattices. NTD is colored in blue/cyan, CTD in orange/red. d, e Detailed views of the dimer (top) and trimer (bottom) interface in the immature (d) and mature (e) lattices.
