Amino acid IUPAC code. See also https://www.bioinformatics.org/sms/iupac.html or https://en.wikipedia.org/wiki/International_Union_of_Pure_and_Applied_Chemistry.

Remarks:

• Question marks (?) are interpreted as unknowns (same as X). However, when a sequence is printed/exported, Xs will be used.
• Full stops (.) are interpreted as gaps (same as -). However, when a sequence is printed/exported, -s will be used
