DESCRIPTION

Also known as CREN1_PYRCJ, cren-1. Forms the backbone of an actin-like archaeal cytoskeleton, which is involved in cell shape determination. Has ATPase activity. Shows highest activity towards ATP or GTP as nucleotide, and only residual activity on UTP, CTP and dNTPs. Monomer. The crenactin monomers polymerize into right-handed helical filaments, with 8 subunits per complete turn of the helix (PubMed:24531483, PubMed:24486010). Forms single-stranded filaments under high salt concentrations and double-stranded filaments under low salt concentrations (PubMed:26124094, PubMed:27852434). Interacts with arcadin-1 and arcadin-2 (PubMed:27852434).
