Original-Style Sequences 1.75

  • Explanation: A SCOP domain may include fragments from different PDB chains (see d1cph.1, for example). A genetic domain is a SCOP domain in which the fragments are concatenated in the order in which they appear in the original gene or sequence. In the original-style Astral SCOP sequence sets, there is a separate entry for each chain (the section of d1cph.1 in chain A: becomes e1cph.1a, and the part in chain B: becomes e1cph.1b). In the genetic domain sequence sets, there is a single entry, g1cph.1, in which the sequences for chains B: and A: appear in the correct order, separated by the letter 'X'.
    Genetic domain sequences are now the default.
