Sequence-based queries may include NC-IUB ambiguity codes. Internal loops and multibranched loops can be searched by separating the individual loop segments with a '-' character.



Single strand search:




For a query sequence of N bases, the input range is [0,N]. The default value of 0 will be used when ambiguity codes are present in the query sequence or the input is negative. Similarly, N will be used if the input is larger than the length of the query sequence.

Enter a 4-character pdb id. The search may be restricted to an individual chain, by attaching ':chain-id' (e.g., 2tra:A), with '%' matching any chain.
