| + | Several archaeal mechanosensitive (MS) channels have been reported, including one from Thermoplasma volcanium designated MscTV. Here, we report the crystal structure of MscTV at 1.6-A resolution. Unexpectedly, MscTV was found to be a water-soluble protein exhibiting a winged helix-turn-helix (wHTH) motif, which is the signature of the MarR (multiple antibiotic resistance regulator) family of transcriptional regulators. A cell-based osmotic downshock functional assay demonstrated that MscTV was unable to protect a knockout strain of Escherichia coli from hypoosmotic shock, further indicating that it does not function as a MS channel. We propose this protein be renamed MLPTv for MarR-like protein from T. volcanium. | ||
