Cysteine 64-73 monoamine oxidase A Homo sapiens 29-54 8316221-1 1993 Nine cysteines are found in the deduced amino acid sequences of both human liver monoamine oxidase (MAO)-A and MAO-B. Cysteine 5-14 monoamine oxidase A Homo sapiens 81-106 8316221-2 1993 The role of these cysteine residues in MAO-A and -B catalytic activity was studied by site-directed mutagenesis, whereby each cysteine residue was converted to serine. Cysteine 18-26 monoamine oxidase A Homo sapiens 39-51 8316221-2 1993 The role of these cysteine residues in MAO-A and -B catalytic activity was studied by site-directed mutagenesis, whereby each cysteine residue was converted to serine. Cysteine 126-134 monoamine oxidase A Homo sapiens 39-51 8316221-6 1993 Substitution of MAO-A Cys-374 and -406 and MAO-B Cys-156, -365, and -397 with serine resulted in complete loss of MAO-A and -B catalytic activity. Cysteine 22-25 monoamine oxidase A Homo sapiens 16-21 8316221-6 1993 Substitution of MAO-A Cys-374 and -406 and MAO-B Cys-156, -365, and -397 with serine resulted in complete loss of MAO-A and -B catalytic activity. Cysteine 22-25 monoamine oxidase A Homo sapiens 114-126 8316221-6 1993 Substitution of MAO-A Cys-374 and -406 and MAO-B Cys-156, -365, and -397 with serine resulted in complete loss of MAO-A and -B catalytic activity. Cysteine 49-52 monoamine oxidase A Homo sapiens 114-126 8316221-9 1993 The loss of catalytic activity of MAO-A Ser-374 and MAO-B Ser-156 and -365 suggests that these cysteines are important for catalytic activity, but whether they are involved in forming the active site or are important for the appropriate conformation of MAO-A and -B remains to be studied. Cysteine 95-104 monoamine oxidase A Homo sapiens 34-39 8316221-9 1993 The loss of catalytic activity of MAO-A Ser-374 and MAO-B Ser-156 and -365 suggests that these cysteines are important for catalytic activity, but whether they are involved in forming the active site or are important for the appropriate conformation of MAO-A and -B remains to be studied. Cysteine 95-104 monoamine oxidase A Homo sapiens 253-265 3242595-10 1988 The ability of N-C alpha MBA to undergo attachment to a cysteine residue in both MAO A and MAO B may lead the way toward peptide mapping of the two isozymes in order to determine differences in their primary structures. Cysteine 56-64 monoamine oxidase A Homo sapiens 81-86 1886775-7 1991 Exon 12 (bearing the codon for cysteine, which carries the covalently bound FAD cofactor) and exon 13 are highly conserved between human MAOA and MAOB genes (92% at the amino acid level). Cysteine 31-39 monoamine oxidase A Homo sapiens 137-141 12777388-0 2003 Structural comparison of human monoamine oxidases A and B: mass spectrometry monitoring of cysteine reactivities. Cysteine 91-99 monoamine oxidase A Homo sapiens 31-57 12777388-3 2003 Human MAO A and MAO B each contain 9 cysteine residues (7 in conserved sequence locations). Cysteine 37-45 monoamine oxidase A Homo sapiens 6-11 10877844-1 2000 The FAD binding site of human liver monoamine oxidase A (MAO A) has been investigated by mutagenesis of the amino acid site of covalent FAD attachment (Cys-406) to an alanyl residue. Cysteine 152-155 monoamine oxidase A Homo sapiens 36-55 10877844-1 2000 The FAD binding site of human liver monoamine oxidase A (MAO A) has been investigated by mutagenesis of the amino acid site of covalent FAD attachment (Cys-406) to an alanyl residue. Cysteine 152-155 monoamine oxidase A Homo sapiens 57-62 10438531-9 1999 A flavin peptide was isolated from MAO A containing 7-nor-7-bromo-FAD and was demonstrated to be covalently attached to Cys-406 by an 8alpha-S-thioether linkage by sequence analysis and by matrix-assisted laser desorption ionization time of flight mass spectroscopy. Cysteine 120-123 monoamine oxidase A Homo sapiens 35-40 16127378-12 2005 Modification of multiple thiols results in inactivation but mutation of a single thiol, cysteine 374 in MAO A to alanine, decreased the catalytic potency (kcat/Km) by 30%.
