A-minor

The A-minor motif is formed when an adenosine interacts with the minor-groove of a receptor base pair, which is usually a Watson-Crick base pair. The A-minor motif can be divided into 4 types based on the position of the inserted adenosine relative to the receptor base pair.

Currently NASSAM will only search for Type 0 and Type I A-minor motifs. The representations of other A-minor motifs are in progress.
