Structure of rat monoamine oxidase A and its specific recognitions for substrates and inhibitors.
J.Ma, M.Yoshimura, E.Yamashita, A.Nakagawa, A.Ito, T.Tsukihara.
Monoamine oxidase (MAO), a mitochondrial outer membrane enzyme, catalyzes the degradation of neurotransmitters in the central nervous system and is the target for anti-depression drug design. Two subtypes of MAO, MAOA and MAOB, are similar in primary sequences but have unique substrate and inhibitor specificities. The structures of human MAOB complexed with various inhibitors were reported early. To understand the mechanisms of specific substrate and inhibitor recognitions of MAOA and MAOB, we have determined the crystal structure of rat MAOA complexed with the specific inhibitor, clorgyline, at 3.2A resolution. The comparison of the structures between MAOA and MAOB clearly explains the specificity of clorgyline for MAOA inhibition. The fitting of serotonin into the binding pockets of MAOs demonstrates that MAOB Tyr326 would block access of the 5-hydroxy group of serotonin into the enzyme. These results will lead to further understanding of the MAOA function and to new anti-depression drug design. This study also presents that MAOA has a transmembrane helix at the C-terminal region. This is the first crystal structure of membrane protein with an isolated transmembrane helix.

Figure 8.
Figure 8. Inhibitor and substrate-binding models in MAOA and MAOB. Figures were produced by same method as for Figure 7. MAOB residues are shown as semi-transparent. (a) Inhibitors of MAOB are superposed on clorgyline in the active center of MAOA. The colors used to discriminate the different inhibitors are red for clorgyline, cyan for pargyline (from 1GOS), green for 1,4-diphenyl-2-butene (from PDB code 1OJ9), blue for isatin (from PDB code 1OJA), purple for tranylcypromine (from PDB code 1OJB), and orange for N-(2-aminoethyl)-p-chlorobenzamide (from PDB code 1OJC). (b) 5-HT is built into the active center of MAOA and is shown as a ball-and-stick model.
Figure 9.
Figure 9. Postulated membrane-binding regions of MAOA. (a) Membrane-binding model of MAOA. The C-terminal structure of molecule D is calculated according to the molecule C to show a sound CD dimer structure of MAOA. The molecule D is shown in transparent mode. Positively charged residues that are postulated to interact with membrane surfaces in molecule C are shown in ball-and-stick model. The mitochondrial outer membrane surfaces are indicated by two continuous lines. (b) stereo view of the detailed structure of membrane-binding regions of molecule C of MAOA. The orientation is the same as that of (a). Tryptophan and tyrosine residues are labeled.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
