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-styleASTRAL 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.
