3.6.1.59 | hanging-drop vapor-diffusion method at 20°C. Structures of DcpS in ligand-free form and in a complex with m7GDP. Examination of the crystallographic B-factors indicates that the N-terminal domain in apo-DcpS is inherently flexible, and in a dynamic state ready for substrate binding and product release | Homo sapiens |

3.6.1.59 | dimer | in contrast, and similar to the m7GpppG-DcpS complex, DcpS with bound m7GDP is an asymmetric dimer in which the closed state appears to be the substrate-bound complex, whereas the open state mimics the product-bound complex. apo-DcpS is a symmetric dimer | Homo sapiens |
