Intrafilament nucleotide exchange in a prokaryotic actin homolog
Polymerisation and disassembly govern the cellular functions of cytoskeletal proteins.
Polymerisation and disassembly govern the cellular functions of cytoskeletal proteins. In canonical nucleotide-dependent polymers such as actin and tubulin, nucleotide exchange occurs in soluble subunits but not within intact protofilaments. By contrast, the assembly dynamics…
