one- and three-letter codes

    The list of three-letter codes for amino acids includes
ASX  'ambiguous asparagine/aspartic-acid' but it is missing the
corresponding GLX 'ambiguous glutamine/glutamic acid'.

    The list of one-letter codes for amino acids is missing both
B which corresponds to ASX and Z which corresponds to GLX.

                           Sincerely,
                           Frances C. Bernstein
