Structure of the Hypothetical Protein Ton1535 from Thermococcus Onnurineus Na1 Reveals Unique Structural Properties by a Left-Handed Helical Turn in Normal Alpha-Solenoid Protein. Proteins, 82:1072-, 2014 Cited by PubMed Abstract: The crystal structure of Ton1535, a hypothetical protein from Thermococcus onnurineus NA1, was determined at 2.3 Å resolution. With two antiparallel α-helices in a helix-turn-helix motif as a repeating unit, Ton1535 consists of right-handed coiled N- and C-terminal regions that are stacked together using helix bundles containing a left-handed helical turn. One left-handed helical turn in the right-handed coiled structure produces two unique structural properties. One is the presence of separated concave grooves rather than one continuous concave groove, and the other is the contribution of α-helices on the convex surfaces of the N-terminal region to the extended surface of the concave groove of the C-terminal region and vice versa.
