Amino Acid Sequences of MAO A & MAO B Isoenzymes



The alignment of deduced amino acid sequences of human liver MAO A and B.

Amino acids are numbered on the left side.  Identical amino acids are indicated by asterisks.   Dashes mark spaces introduced for maximum alignment of identical residues.  Pink or blue shade denotes amino acids in each exon.  Identical or divergent amino acids at the 5’ or 3’ boundary of the introns are indicated by bold asterisks or filled circles, respectively.  (Adapted from Bach et al., 1988; Grimsby et al., 1991)
